I have just ordered the collection from Sara. We shall see how we go! I
cleared an area of bench last week and thought that I might try some phal.
species − I was already hunting around the German websites so was delighted
to receive Burnham's offer.

I too have been getting interested in phal species, and have bought a dozen or so, but buying weenies, mainly from ebay − a lot of stuff i ave not seen on sale before. All have been tied or wired or glued to bark mounts. Amazingly enough, after a few months,all are alive, and most are starting roots.

That was the final nail today ; having a bad night, I sat down in front of the PC at 3 am, and discovered that it was in the middle of some updates, so I left it alone and went and used my iPad.
Today I had a problem in the post ( the Bank had 'lost” a Direct Debit instruction, not paid anything on one of my credit cards, and got a letter with a fine, and a statement of the interest being added.)..
After getting to the bottom of it on the phone, I composed a suitable letter to the Bank, and another to the credit card people explaining, and then tried to print... two hours later I discovered that the problem was that the WEP code had been deleted for the wireless link to the printer and found how to reset it , done so , and then – when I tried to open the saved letters – 'windows has a problem opening these files...”.
I did a system restore, on the basis that nothing would be lost , and when I tried again the files had disappeared, problems and all.
I went out to PC World to buy an iMac, but after a chat with a very helpful salesman, realised that the new model coming in December has a lot extra included for little extra cash , and whilst it was pointed out that I could buy it for the present model, I finally decided to wait a month or so.
Then, to complete the wasted day, spent time on the Apple web-site – 'pre-order your iMac”... and could not find how to do that.

I did bring a few plants in to photograph, earlier today, but have not had time to look at them. Maybe I can do it now, although we have family coming to stay for the week-end due any time now – step-son likes his nip – I think we’ll share a bottle before bedtime .

I too am tempted by the offer, especially as I used to grow both
schilleriana and stuartiana years ago, but I no longer have a 'warm'
greenhouse. I wonder if they would grow in the home or if species
phals are a bit more particular in their requirements that the
bog-standard hybrids?

I no longer have a hot house but am thinking of putting the small plants in
the base of a heated propagator in the intermediate. Probably use the lid at
night but take it off during the day to let the fan get at the plants.

As my collection of laelia anceps varieties was getting rather large, I
decided to convert the hot section to a specific climate zone. The adult
phalaenopses seem to be OK in the intermediate.

My sympathies, Geoff! I spent part of yesterday cursing my netbook. I don't
use it very often, mainly to record data from my greenhouse data
logger and to update the SkyScout, so when I do it decides that
MicroSoft Security Essentials is out of date and spends ages
updating. That I could just about cope with but more often than not
it will say Security Essentials is not responding or isn't installed!
Fiddle with it for half an hour and restart and suddenly it's decided
to connect and update which means I can't do anything until it's
finished. Grr. I thought it might help to fire it up more often e.g.
every other day, but it still took an age. To add insult to injury it
didn't recognize the data logger at first but luckily I removed it,
plugged it in again and finally got the desired response. It's just
so frustrating.

In your third para you mention WEP code. I hope you meant WPA or WPA2

Hi Geoff and Tricia,

Obviously, I wish neither of you bad luck in your computer experiences but, at least, take great comfort from the fact that such experiences make me feel more a member of the Jumped Ship Club than simply an inept operator fallen into the water.

My wife used to ask me why it was that "no one else has these problems" and I'm not sure that my answer, "because they come and ask me to solve 'em", ever convinced her. It is a fact though, that the problems of others are more interesting than one's own and often actually solvable. Sometimes, the blind leading the blind actually works.

Incidentally Tricia, Re; 'Back to the drawing board during the building of the cathedrals would have involved sanding the floor and scratching a new plan on it. The poor devils that had to do the hard graft didn't have sliced bread for their sandwiches though, did they? They were waiting for the best things to come I suppose. A bit like Geoff waiting until next month for his Apple to ripen.

Cheers (ps; I spent yesterday coughing and sneezing)

Sympathies Geoff − computing and modern finance are incredibly productive
until one little thing goes wrong, then it snowballs and no one wants to
know. Phone calls are long and expensive to 0845 numbers, you just have
to plug away and keep calm but you seem to be doing that OK. I am being
driven to distraction by my Virgin WiFi super hub, it only works for an
hour or so. I have had two engineers take over the machine for an hour
plus and it still doesnt work so I feel I am being driven to drink but
don't have a nice step son to sup with! The maddening thing is that when
it works it is superb.

Hi Geoff,
In 2004 (I think it was), Nikon conceded a Coolpix problem by heavily discounting to me a D100 DSLR (which was never a good seller anyway!). It was then considered as part of their 'professional' range. It was (and still is) a nice camera but for the problem of dust on the sensor and weight. About a year ago I bought a D5000 which doesn't seem to be troubled with dust and is lighter but, as a 'prosumer' job, it was selling for less than half the D100's discounted price. All we need to do is last 8 or nine years and the D800E will then be a relative 'cheapo'. I'll help you to carry it but where would you store the thousands of superior images? And just imagine the software to edit all those Megapixels!

By the way, my local Sainsburys sells a "professional' toothbrush; who buy one and what is the salary scale of their profession?

Hi John,

Hope the coughs sneezes go away soon :-)

As for computers I guess in my case it is partly lack of familiarity
with Windows. Some years ago I needed an alternative to RISC OS
(formerly Acorn until the company was asset-stripped) because RISC OS
was getting left behind and the Mac OS is much closer from a user's
point of view than Windows. I have the best of both worlds because I
still use virtual RISC OS on the iMac and find it easy to swap from
one to t'other. Windows continues to baffle me when it 'says' one
thing and 'does' another − I'm used to more consistency.

On the other hand, i have a "friend" − actually the only connection is that we were both on the same committee , but he is , it seems, secretly something of a fascist . He has added me to his mail list and sends me half a dozen mails every day: mostly humourous stories, but always with a racist or sexist twist. I find them offensive.
In Windows it is so easy to block them . All his mail goes straight to delete. But I have not found how to do that on the iPad. This is the other side of the Windows/Apple coin. If it is possible, I suspect that it won't be easy, whereas in Windows it is easy.

Tricia,
When you say "it 'says' one thing and 'does' another ", it is clear that you aren't keeping up with changes in the English language.
I have just received a BT telephone bill informing me that my previous bill is, as yet, partly unpaid. I was curious because I pay by direct debit but I am assured by their Indian colleagues that it is unpaid to the tune of minus £24. In other words, I owe BT minus £24 and so, for mathematical simplicity they will refund me plus £24 asap. After all they are communications specialists and so it must very clear really. I even have to stop my car by holding down the start button but my local 20mph road sign does read "The road ahead 20" . Obviously not the road behind then!

As for the specifics of computers, it is really amazing that forums like OT can be operated with such a diversity of hardware and software and used by humans, not all of whom understand most of the diversity of acronyms.

able to do it with your iMac, but bizarrely Apple didn't include this

Subject: CAM orchids (and communication with other orchid forums)
Date: Sun, 04 Nov 2012 14:20

I recently became caught up in the unpopular (for orchid collectors) scientific physiological topic of CAM plants discussed in the forum;
. Just to remind members of OT, CAM (or in full Crassulacian Acid Metabolism) is a 'trick' used by some 50% of orchids which try to minimise water (transpiration) loss during the heat of the day. Most members will know that there are micro pores (stomata) mainly on the undersides of leaves, through which CO2 enters and O2 and water vapour escape as essential parts of the photosynthesis process.

Some plants (Crassulas, some orchids and others) have evolved a strategy whereby they keep their stomatal pores closed (no gaseous exchange) during the day to avoid water loss. They open their stomata at night when photosynthesis is not possible (no sunlight). However, that is when they take in (through their stomata) CO2 which is then stored (in terms simple enough for me) in malic acid. During the heat and light of the day, photosynthesis can draw on the stored CO2 without significant water loss.

I have often wondered if CAM orchids are grouped in a way that supports their early evolution under arid conditions. It is apparent that some CAM orchids live in conditions where their special physiology is no longer required (ancestral inheritance?) and, so I understand, the CAM mechanism is more variable in its application than my simple illustration suggests. Also, the microclimates in some generally non-arid climates, can be quite dry (consider the humidity range of epiphytic orchids in tall forest trees).

There are a couple of questions I'd like to ask; 1- is there anyone 'out there' who can provide a more accurate analysis of the process for orchids, with relevance to the evolution of these plants? 2 − I am aware that commercial growers 'play about' with the concentration of CO2 in their greenhouses but I am not sure whether or not this is through an application of CAM principles or if it is simply a discovered/accidental advantage.

Lastly; just in case members of happen across this item, I should like you to know that I have tried, in vain, to communicate information about the same reference Oliver Sparrow gave that contains a (full?) list of CAM orchids. For a reason I don't understand, even one-line emails containing the reference 'bounce' back as containing more than the allowed number of lines. For this reason, and hopefully to encourage casual liaison between members of orchid discussions I offer reference to a paper listing many CAM orchids, it is available on the web in full and has many pages of Central American CAM species and, presumably, CAM is likely to exist at their generic level (?). It was cited by Oliver Sparrow but the fact that many CAM species are listed within it seems to have escaped readers of that forum. It is;

Hello all,

For those of you how don't know (yet), I have always grown my collection of orchids indoors. It is a bit of a struggle with Pleuros (being one of my three favourite genera groups), but Bulbos and Phals do excellent for me. I grow mainly species, and have had little problems keeping them indoors in my two bedroom flat. I even have two shcillerianas, one is only a young plant, coming up to flowering size (I bought it as a seedling a couple of years ago), and the other, 'pink butterfly' awarded clone, has flowered for me twice now. One flower first time, 5 flowers this year (again it is only a young plant, so I am looking forward to seeing what I can do with it in a couple more years).

I don't do anything special for them, They grow along with all my other plants, so I don't think you'd have any problems provided your other Phals are happy.

Francis

Subject: Re: CAM orchids
Date: Tue, 06 Nov 2012 10:45

My reading on the subject, entirely through surfing the net, has informed me of research on CAM in orchids done at mostly if not entirely Central or South American Universities, which unsurprisingly used Laelia or Oncidium species as the subject matter. It is my impression from this – never read as an actual statement, that this process is available as an option to many , maybe most, species in these two Alliances ( I think that is the correct term in Dressler's Phylogenetics).

It is obvious, on a little thought, that if you are in Bogota University and want to research something to do with orchids that you are likely to go to those alliances – it would be quite perverse to do it on say Bulbophyllum, or one of the Vandaea which are not available just outside your back door. Which is not to say it doesn’t happen in other taxonomic groups – but no one in the Far East seems to have published anything which Google could find for me on the subject.

I do not know what it is that makes CAM possible ; I assume a specific set of protein chains, which means a particular gene(s) ; but the more we know about the genome, the more it becomes clear that all sorts of genes are sitting there in the DNA but are inactive, because not switched on. And my knowledge of what causes switching, and whether it is in another part of the genome that the switches are located, is abysmal – if you are anywhere near ignorant as I am ( and remember that I am an auto-didact on all subjects) try this US source-.http://ghr.nlm.nih.gov/handbook/howgeneswork/geneonoff

Dawkins popular science books about genes makes it clear that once coming into existence, they can lurk through successive major phases of evolutionary development – so if CAM ever was an advantage, even to the proto-orchid, which , from the Kew DNA boys clade maps can be guessed to be a proto-lily too ( which also practice CAM) then it may well be in any and every orchid, just waiting for the appropriate environmental situation to switch it on.

As to your second question- CO2 enrichment is a pretty standard horticultural technique – see e.g. http://www.osti.gov/energycitations/product.biblio.jsp?osti_id6151633

As it happens I once discussed this with Ray Bilton in his glory days, before the hurricane at Lewes, and he told me that he had run a trial, but found it was simply uneconomic ; of course other people back to Fred Sander at St.Albans had used it too – I think it was a mixture of soot and lime or some-such, placed on the floors of the cattleya houses in his case . But I doubt if Fred Sander did a cost analysis, and fuel cost was not such a significant factor in those days. Quite probably the coke-fired boilers, often actually in the greenhouses ( there were no less than 54 'stoke-holes” at that nursery ! ) with leaky flues, did quite a bit of CO2 enrichment – and CO as well (!) without thinking of extra.,

As a matter of practical interest to orchid growers, the knowledge that their cattleyas do not actually need a high humidity in daylight hours when in the season of growth , since they can take in and lock up all the CO2 they need by the carboxyl route in night hours, may be some kind of relief.

Personally I do not take any measures to humidify my orchid house, since the water I use in ordinary cultivation is ample – I spray about 30 litres into the atmosphere on my hanging plants, bare root plants growing on mounts , etc every day, on average; and also my ground level is below the water table even in normal years, never mind year when my rain gauge does not have enough figures to show the total in mm, so switches to cm…

I have found that when I mention CAM , or attempt to produce a 'popular science” piece for my Orchid Society Journal, and get into differences between the three possible routes for photosynthesis , eyes glaze over ; which may be my lack of Dawkins style finesse, but I suspect is more a matter of pragmatics – 'so what”, or 'can we change it”, and a lack of thirst for knowledge for the sake of knowledge.

Cheers, John.

I see that you grow bowringiana hanging up, which I imagine it enjoys. Is it in a pot or on a block or raft ? They are lovely things this species, and there are some good clones in USA, some of which I am led to believe- have flowers which are much longer lasting than the basic species ones. I wish I could get one/some , since the short life is the one drawback of this lovely thing.

I like your paliolata that many flowers speaks of successive years of doing things right !.

As to turkheimii , I have at least two species of Pleuros which look exactly the same apart from flower colour. It must be a basic type or maybe just one species which gets a different name every time a different colour is found.

Thanks for posting

I did not answer your question in my first reply, but no, they will normally flower every year.

Just to add to the variations in culture/results with orchids my Thunia
gattonensis that has been growing in rockwool for two years flowered and
grew well this year. A young Thunia alba, also in rockwool, has grown to
good flowering size for next year.

Geoff,
My Cattleya bowringiana is in a black plastic basket designed for pond
plants and hangs in the roof of my greenhouse which it seems to like.

Hi Alex,
I read your Thunia concerns. I can tell you what I know about Thunia gattonensis and Thunia marshalliana. Gattonensis is the most beautiful of the two and grows rather better. They are terrestrial and deciduous. Now is the right time, in the UK to dry them out, but the falling of the leaves tell you exactly when to let it dry out. During the Spring each new cane will produce 1,2 or 3 new canes, so they multiply quickly. They need to sit completely dry throughout the winter and the old shrivelled canes can be cut off now or even left to dry further. Last year I hung my canes from the roof in a cool greenhouse but a friend of mine who grows them spectacularly just puts the dry Plant in a cold bedroom over winter. In the spring a new growth will appear at the bottom of each cane. Bring the canes back into a intermediate zone and let them develop to about an inch or an inch and a half in length. Don't pot them up yet or give them any water. They grow well in most terrestrial peaty type composts or in Rockwool cubes. In a few years you will have seven or eight canes. Once the new growths are at least 1 1/2 inches long,the canes can be arranged in a teepee fashion, tied at the top with the bottom of the canes just resting on the compost in an 8 to 10 inch diameter pot(around the circumference of the pot about 1/2 inch in from the edge of the pot). At this stage you can start watering and feeding them profusely. 750 micro Siemens feed concentration and at least every two days as the weather hots up. They like a very bright position and full afternoon Sun is OK. Be very careful not to get any water on the new shoots or they will rot or at least have bad leaves. They flower in about May time and the flowers last for about two weeks. A well grown Thunia gattonensis is stunning. Keep the feed regime going after flowering to fatten the canes.

I hope that this helps.
John Dennis

Well how odd that yours have not flowered either, orchids can be so
puzzling, I suppose it is just wait and see now, anyway thanks for the
info Geoff.

They are all very floriferous plants Bill. I like bowringiana, I should
get one as I believe they can do quite well as a house plant.

Indeed Bill. ; the only reason i went to rockwool cubes is because a member of my Society hpias a magnificent Thunia grown in it. In fact I think it was best species or even Grand Champion at Peterborough last year. Grown in a bucket sized pot with 15, 20 ? Maybe more flowering canes. I copied him, but it just does not work for me. Horses for courses.
So yes, they can grow well in rockwool cubes, I don't doubt it. But. Not for me.

Very detailed culture notes Dennis, thanks, I will keep this email. My
thunia is gattonensis and I got it as dry pencil thin stick in the club
raffle. I have essentially followed your regime and in 2010 had a strong
stem which died off and two good stems then grew giving me flowers in june
2011, now there are three and no flowers! It is puzzling and Bill Haldane
has just said his have bloomed , one being in rockwool which has not
worked for Geoff. Orchids are tricky things no doubt about it. Maybe it
is just the dull wet summer we have had. Thanks for instructions.
Regards, Alex

Lovely set, Bill − and great to see someone else grows P. palliolata.
Mine is currently flowering but nowhere near as prolifically as
yours. It is also far less compact so I'm wondering how you grow
yours in comparison.

Hi Tricia,
I must admit to having my P. paliolata for a number of years, but it
gets much the same treatment as my other Pleuros. Compost sphagnum,
perlite and a little medium bark, kept on the wet side in the cool end
of my greenhouse. As you will have found it is very easy to propagate
from leaf stem ends.

Hi Bill,

That sounds very similar to the conditions here. I suspect the only
difference will be light levels. Mine is currently in extreme shade
so I will try it in a lighter area.

Fingers crossed,
