Hi All you you gurus.

1st let me say I nearly failed genetics in School and have since forgot everything.

Do you any of you know the parentage of Cat. Chia Lin the large purple Cat with a nice scent?

Or maybe a better question is? Which Cats did the largeness originate from? And which Cats Pass there scents along (dumb genetics question)?

Thanks,

Jim

BLC Chia Lin is a complex hybrid containing genetic material from 16 species and 14 of these are fragrant. However nearly half of it's genes are from Cattleya dowiana which is both fragrant and large flowered.

Hi all,

I live in the middle of "Cat Dowiana land" (in Costa Rica) I have many.. The ruffledness from Dowaina is fairly obvious, my Dowianas do not have much of a scent.

I guess this question leads me to many others. Like where did the get the strong colors from? From what I am reading , that is the trick. Anyone have any insight (perhaps a book, websites) on dominate genes? when 2 plants are breed one will pass the color, rougheled lip, big size. I am sure there is some science here somewhere.

For example sherry baby the chocolate Oncidium hybrid. when you cross that with another Onc will the color or scent pass? Many questions....

Thanks,

Hi all,

At the BOGA show on August 27th 2004, my wife purchased a flask from Ratcliffe Orchids.

The name shown was: Paphiopedilum Honey x Landmark 'Leader'.

She looked after them very well and the first one to flower is attached.

Subject: Cycnoches Peruvianum
Date: Tue, 24 Oct 2006 20:15

Hi all: I was hoping that someone could please help me with what to do with
this plant. It is a Cycnoches Peruvianum that I got last year at this time.
It was in bud when I got it but the bud blasted (from the leafless bulb at
the right). It never lost its leaves until after it had begun a new growth,
so I kept on watering it rather than resting it. That growth bloomed this
summer with a single female flower. At the same time it began the 3 new
growths visible in the photo. As you can see from the closeup, the leaves
are getting this crazy raised splotching. There are no obvious bugs on the
plant, but I did give it a douse with Orthene and later with insecticidal
soap. I know this plant SHOULD lose its leaves and go dormant until the
spring, but apparently it doesn't know this! It is looking like it will lose
the leaves on the large growth, but the new growths also have these raised
spots.
So the questions are: Should I stop watering it and risk losing the 3 new
growths, hoping that in the spring another few eyes will grow, or do I just
continue with decreased watering over the winter. It is under 400W HPS in a
south window, so it can get lots of light. The info I have read said they
like tons of water when in growth, hence the dilemma. If anyone could please
advise, I would be most grateful. Secondly, does anyone know what would
cause that weird bumping on the leaves?
Thanks in advance

I think that other orchids which I do know about ( unlike Cycnoches which I
have never grown until buying some at BOC this year) are supposed to drop
their leaves in the autumn and go into rest , but will be reluctant to do so
unless encouraged − e.g. by a temperature drop and a reduction / absence of
watering. Maybe a change of light too. What to do now ? Ah , there's the
rub. Me , I'd carry on watering , and try harder next year.

BTW , the Cyc. I bought, in bud, were potted in Perlite, given one watering
to settle the compost, and then hung up in the greenhouse and not watered .
Many spikes are developing !.

Well done to flower paphs in under 2 years from flask , something I have
managed just once before ( and that was with P.Papa Rohl , primary hybrids
between species and complex tend to be very vigorous)

I am sceptical of the label however . What you have is virtually the species
P.spicerianum. Probably it is that species , since the labellum is so
precisely right ( apart from everything else).

I know one of the parents very well , P.Honey , and raised a flask of 25 of
them which were extraordinarily consistent. But when I looked it up I
realised that although nominally a hybrid, the parents were at one time
considered to be varieties of the same species and very little different
from one another ( and nothing like spicerianum.)

I haven't been able to look up Landmark yet , as Wildcatt won't run on my
desk-top pc but only on an old lap-top which is currently not available,
but it sounds like a complex paph. As such it could have spicerianum in its
background, and whilst throwbacks do occur, you never ( in my experience)
get a throwback to something looking like a pure species from a complex
hybrid. It's like mixing a lot of colours together − you don't get a
rainbow, what you get is mud colour.

Not that your plant is any the worse for not being what it's supposed to be
, I am not suggesting that. Anyway , if there were more than one seedling
in the flask, it will be interesting to see what the others are like. If
they are all different , then, well, maybe this is the one in a billion
throwback. If they are all the same, then it's a simple case of a label
muddle.

Paph Landmark is P. glaucophyllum x P. sanderianum.
Rockys plant is definitely a very nice P. spicerianum. With that, it is a fine effort to get it to flower in two years. I know growers who cant flower it after five years. I think rocky or his wife need to have a ' heart to heart' discussion with Ratcliffes.
The cross that was supposed to be, would take a number of years more to flower.

I have the same problem, with both C. amazonica and discolor (but without
such good flowering!). They don't appear to like humidity. Siting them
directly in the current of a strong fan seems to help. Applies to the
conditions here, may not be suitable elsewhere.

Hi Tricia and Dennis,
I have a plant of this also and have managed to flower it this year. I don't
have the problem you appear to have. My plant is sprayed with water direct
from the hot water tap once or twice a day as I remember. It sits under two
60 watt tubes in an old laminar cabinet and with not a lot of humidity. The
medium is coconut chips.Did you both by any chance purchase from the same
source?

It is ( was ? ) my belief that these are cloud forest species . So why can't
they stand humidity ?
Maybe they don't like our bacteria ? This is a serious suggestion. Try a
monthly spray with Physan or another plant broad spectrum
disinfectant/bactericide/etc.

My Cyc came from Orchis − which I think is Joseph Wu ? The people who have
the meristems of the flambuoyant cattleyas at the main shows. ( But when you
get them home the roots are crammed into tiny plastic pots full of dry moss
- with nary a live root in sight. Still , they do seem to recover.).

I bought several, some of which are Cycnoches, and others are some
intergeneric hybrid with a different abbreviation . I haven't studied this -
waiting to see if they grow , before I get too excited. But the fact that
they have big cigar-like bulbs sprouting flower buds everywhere suggest that
they are excellent plants, and since they are totally deciduous ( my plants,
at any rate) I assume that they are going to grow a complete new set of
roots when a new growth starts in the spring.

New species ? it is the great thing about orchids, that when we start to get
a bit bored, there is always a new challenge ; I've gone onto Bulbophyllums,
and also Encyclias , lots to choose from amongst both of these.

I have been growing various Cyp. seedlings outside in pots which are now covered with a green carpet of moss.
What I want to know is (because of the amount of torrential rain we have been getting) should I now take them inside to dry out or should I chance leaving them out until the frost comes hoping that they will dry out naturally beforehand?

That's orchids for you! I got my discolor from Peter White last year and
the amazonica was bought at a Newbury Show a few years ago, but I can't
recall the vendor. I am growing (?!) them in a bark, sphagnum and foam mix
in clear pots. When there is no condensation visible I stand the pot in a
saucer of rainwater for a day or so, then drain it. They seem to like it so
far but that could change overnight...

I read the recent correspondence from our Club members regarding the various markings/ailments with soft leaved orchids with much interest.

As I have always said, Mother Nature does not give up her secrets very often, if seldom at all.

So it is down to us to try and work out why such things happen.

At the moment I have a Cycnoches in bud and the leaves look wonderful. My greenhouse is quite damp to very humid at night, so I do not think that too much humidity is the problem.

It does seem that orchids with soft leaves will almost always suffer at some time in their life. Let's face it, there is not much substance in these type of leaves, so that they may often show some ailments much quicker than others.

In the case of the leaf losing types I would think that it is quite natural. Especially as they grow and loose their leaves in the space of a few months.

I remember the Catasetums that I saw growing in Mexico earlier this year, and standing beside them one does tend to get a 'feel' for certain things.

A tough old Cattleya or Laelia or Dendrobium speciosum leaf will stand looking very good for some years.

Just a few thoughts.

And my final thought is about the leaves of Zygopetalums..........why do they so often turn black???? Maybe it is just nature after all.

Regards, Rocky.

This may just be a wild guess, but perhaps it is wrong to assume they
like constant humidity? I had similar problems when I kept my plants (no
Cochleanthes) in constant humidity − what I did to fix it (and it seems
to work) was invent the 'cloud chambers' that I have described a long
time ago on this list: basically a deep plastic tray with a tall perspex
'fence' around (open at the top!) and a cheap ultra-sound fogger.

The reasoning behind this is that many orchids look rather like
succulents in that they have a number of traits that protect against
water-loss: fat pseudobulbs, thick leaves (or deciduous ones), etc. And
succulents in general need to dry out − so I reckoned that maybe my
orchids need the same. Also, when you think about it, many cloud-forests
are not covered in mist all the time; rather they get a serious
'soaking' in morning and then the sun dries them out, which is exactly
what happens in my cloud-chamber contraption.

The problem is a combination of temperature and humidity. If the
temperature sinks below a certain limit then the humidity causes
black spots on leaves and flowers. I had the same problem with
my Phallies. The white flowers always had black spots. This year
I kept the minimum night temperature at 20 − 22ºC and all the
white flowers were unblemished. It works also with lower temperatures
if the humidity can be kept at very low levels. However
Zygopetalums is problem that has not been solved yet.

Hi all,

No doubt all of our European members will have noticed the phenomenal growth that is obtained by our 'Dutch Cousins' on all types of orchids. I refer to those that are clearly pumped up with some type of performance enhancing drugs...........part joking of course, but when we see a two or three small pseudobulbs followed by the next years growth which looks like a small coconut it does make one wonder what they do to achieve such a size.

Does anyone know how they achieve this?

Not that I want to buy any of this 'Super feed' as I want my orchids to grow naturally as possible.

The reason that I do ask this question is because so many newcomers to orchid growing are quite amazed, and as you all well know, the next few years growths to not perform so well.

Hello to all of our European fellow orchid lovers.

Because here in the U.K. we do not use the 'Euro', the prices that we have to pay for an orchid is that not easily and quickly exchanged into 'Euros' so that we can see what our European cousins are paying for exactly the same plant.

To give some examples:

A normal type of Vulystekeara shall we say £13 to £15.......................Eu 19.40

A 'Cambria' orchid £15.....................................Eu 22.40

A Phalaenopsis £13 to £18.......................Eu 26.80

A Vanda in flower in a glass vase. £40....................................Eu 59.70

I can't say that I know the answer, but I have a suspicion. One of the
things that are peculiar for plants is that many of them can function -
thrive, even − with 'too many' chromosomes. In short, the 'normal' state
is to have two sets of chromosomes: they are diploids. However,
sometimes you find plants with more sets, like three (triploids), four
(tetraploids), six (hexaploids) etc. Apparently our modern wheat is a
tetraploid of an older version called einkorn if I remember correctly.
Plants with too many chromosomes are often larger in all parts.

It is possible to mess up the cell divisions in a plant by applying a
substance called gibberellin (http://en.wikipedia.org/wiki/Gibberellin)
to a meristem; then you can take the meristem and grow it into new
plants. I strongly suspect that if you see plants that are unnaturally
large, this is what has gone on.

Hi all,

A have a couple of plants in bloom at the moment.

1. Cattleya Bob Elliot. As you can see from the photo it is quite nice. The only 'problem' which of course is how 'Mother Nature' made the plants. I guess it inherits the 'problem' from C. Mossiae, which always sees the dorsal sepal fall over backwards. Still, I do like this plant.

2. Laeliocattleya Mini Song. Not very pleased with this plant. The colours are not that good and I do not like the fact that the two petals overlap. I have just punched in the name to see what I could find on the Internet and had a good look at other 'Mini Song's'. Most are much better than mine. While I was looking I locked onto a very nice LC. Sierra Skies "Leone". Now that I do like. The web site is: www.colourful-orchids.com

I just wonder if my plants of 'Mini Song' will be any better next time it blooms?
