Ted's paphs and phrags
I deleted the original message before I remembered to respond, so maybe
I won't get to everything. Question 1, what is the difference between paphs and phrags? Well, you can tell just by looking at the leaves. Or I can... I can't say offhand what is different, phrags are usually more conduplicate (folded in the middle) and the substance is different. Tend to have more shine too. The roots are generally different, with paphs having 'fuzzier' roots. This may be reflective of habitat, since many phrags prefer a moister environment. There is a big difference in the flowers, but the easiest one to see is if you cut open the ovary transversely (in the short direction). Paphs have a tripartite ovary, with the chambers non-distinct. In other words, one big kind of three pointy space in the middle. Phrags have three distinct chambers. At least I seem to remember that being one of the diagnostic features, a taxonomist or somebody who has done slipper flasking more recently than I will probably shoot me down. Question 2, can you clone paphs and phrags? Interestingly, the answer is yes. Or at least you can mericlone Phrag. Sedenii 'Blush' (published in Die Orchideen quite some time ago, and repeated by Oak Hill), and stem prop several different Paphs (anecdotally reported to me by a few different growers who I have no reason to disbelieve). I've personally cloned some Phrag Hanne Popow (starting from flasked material, but still...). Mericloning paphs is not very successful. The limiting factor for all slippers seems to be contamination, in that the meristems are hard to get free of fungus. It can be done, but not in a reliable fashion, and getting sufficient material to start often involves destroying most or all of the growing points on the desired plant. The growth media mericloning slippers hasn't been worked out, of course, given all of the other problems. So, given that mericloning very rarely works and is not unlikely to destroy the parent, it isn't really that popular an option. It is a stated 'Holy Grail' of the slipper community, but I suspect most people who actually make money selling and breeding slippers would just as soon keep the status quo. You can get more money for divisions if you can't make a lot of them. Question 3. There is no question 3... Question 4. Is there a difference besides the new world/ old world distinction. Well, yes. See (1). But the big difference is that they are group incompatible. You can't make Phragmipaphiums. There is one (I think only one) registered, but it probably isn't a true hybrid. You can't make Selenipaphiums, or Cypripaphiums either. Or at least not that I've heard. That alone argues that they are different, and substantially so. This may be (and I'm making s**t up here) due to the evolutionary distance - the American continents split off from the supercontinent a way long time ago, these plants have had plenty of time to drift apart. They are certainly related, I don't think anybody will argue with that, but the fact that they look similar is not really of any consequence. And they aren't that similar, really, not if you have seen a lot of each. Dendrobium phalaenopsis and Phalaenopsis amabile are similar to the unitiated too, but they aren't very closely related.

"Rob Halgren" wrote in message ... I deleted the original message before I remembered to respond, so maybe Thanks for this. The only thing you missed was the variability I have seen between successive flowers on the first inflorescence my only phrag has produced. Here is what I wrote: "WRT the one phrag I have, it is a first bloom seedling, presently on its second flower (i.e. the second flower on the first inflorescence it has ever produced), and it seems to me this flower is quite different from the first on the same inflorescence. The first had MUCH richer colours, pink and yellow, while the second seems to have the same colours but mostly washed out. Also, the laterial petals on the first (they are petals aren't they, and not the sepals?) were quite flat while on the second they are twisted like a cork screw. The top sepal on both was and is quite flat. Is such variability in the flowers normal for phrags in particular, or for lady's slippers in general?" You wrote: "And they aren't that similar, really, not if you have seen a lot of each." This is undoubtedly why I can't tell the difference yet, just looking at the leaves and flowers. I am nowhere near the stage where I want to be dissecting such pretty flowers. If they are as different as Dends are from phals, it is just a matter of time before I can tell the difference. But it seems to me that the flowers of phals and those of even the phal type dends are quite different, much more so than those of the lady's slipper genera. Maybe that is a false impression created by the lady's slipper cultivars that appeal to me. Cheers, Ted |

For besseae hybrids (especially) color is influenced by temperature. Colors are always brighter and more intense when flowers develop in cool temperatures. The flowers of the same plant of Hanne Popow (besseae x schlimii) bloomed in the summer and winter can be so different as to cause you to suspect the tags have been messed up. That might be what you are seeing. And the flower size and shape is also determined by the prevailing conditions when the bud develops. A little water stress one day, a stiff breeze the next, a cloud or two on the third... With sequentially flowering plants, the conditions can be different with each flower bud. With plants that bloom their inflorescences all at once, the flowers are more consistent. And I don't think it is wrong to suggest that for many orchids (not just phrags), the first flower is usually the largest, with flowers getting smaller (perceptibly or not) as you get towards the end of the inflorescence.

Maybe that is a false impression created by the lady's slipper cultivars that appeal to me. Dendrobium phalaenopsis is called that because the flowers are like Phalaenopsis. It is an extreme example. The plants themselves are very different. And the flowers are pretty different, but similar enough to cause confusion if you haven't seen a lot of orchids. Phrags and paphs are much more similar to each other (especially the vegetative parts), so there is no shame in not being able to tell them apart at a glance. When you have seen a few thousand of each you will get pretty good at it. I might make a mistake once in a while myself, just looking at plants. With a flowering plant it is much, much easier. Practice makes pretty good (not perfect!). Rob -- Rob's Rules: http://www.msu.edu/~halgren 1) There is always room for one more orchid 2) There is always room for two more orchids 2a.

Rather, he says, practice makes permanent, and only perfect practice makes perfect. Cheers, Ted |

That flower dropped off after several days in my house, and the second, current flower was produced under lights, with RH around 50% right now. I have no idea what is in it's background. The tag is hard to read, because of the thickness of the marker used to write it, but it looks like Phrag. Dan Wimber. Cheers, Ted |

I believe the vendor bloomed it out in his greenhouse, which is quite humid. That flower dropped off after several days in my house, and the second, current flower was produced under lights, with RH around 50% right now. That would explain a lot... That and the stress of moving from one place to the other probably doesn't help much. I have no idea what is in it's background. The tag is hard to read, because of the thickness of the marker used to write it, but it looks like Phrag. Dan Wimber. Don Wimber, actually. That is besseae x Eric Young. Eric Young is besseae x longifolium. So you have Phrag. besseae as a parent and a grandparent. That explains a lot of your color issues... Don Wimber is one of my favorite phrags. A great hybrid, and easy to grow and bloom. A weed, actually. Good choice. If you like it, you might also like (now i sound like Amazon.com!) Hanne Popow (besseae x schlimii), or Jason Fischer (Mem. Dick Clements x besseae - also two doses of besseae). Those are a couple other easy and very attractive ones.

Ted,
After Rob's explanation of the differences, when a flower is spent and falls off, should be a good time to disect it. I plan to when I next have the chance. Bob "Ted Byers" wrote in message ...

The Phrag flower will fall off looking as perfect as the day it opened. It will sit on the table and MOCK you for thinking it should last longer. So it will even be in good condition when you slice it up. I think I will try too. SuE http://orchids.legolas.org/gallery/albums.php |
