Dave, 

I have been given a flask with 3-4 seedlings of R. chocoensis from Ecuagenera, as well as some other seedlings from Marni Turkel who sowed the seeds herself. So, obviously, there have been several outcrosses or selfings that were succesfully germinated.

Due to contamination issues in the flasks, I now have only one, bushy seedling alive, growing fairly well (better since I positionned it in a warmer spot).

I can't exclude the possibility that those are from spontaneous pods, which may then prove to be a "greenhouse hybrid". Time and first blooming will tell.

Laurent

Hey Carol,

First, I will be in touch later on another item but are you sure that your plant is labeled Pleurothallis chocoensis; there is no Pleuro. species by that name and it probably is the Restrepia.

You are right; chocoensis is a pretty easy grower. My question was a bit loaded in that there are at least 3 AOS awards to chocoensis, with different clonal names - all of which are almost certainly the same clone. For a very long time, all the pieces of this species in people's collections were ostensibly divisions of the original collection. That is a peripheral judging issue but I was curious about whether seedlings have been produced. Laurent, are you certain that Ecuagenera has produced seedlings or  could it be they are selling divisions? I haven't checked with Pepe or Ivan.

As for the regia vs. scobina question, here at BBG we ostensibly have two regia from different sources and two or three scobina from Ecuagenera. In bloom they are all very similar in appearance at least superficially. I would have to say the J&L clone, which is more likely to be what is construed as regia, has a slightly wider synsepal. Right now I do not have the ability to take a closer look at the lips, etc. but will eventually- Laurent, thank you for your response.

Dave

I have a Pleuro chocoensis.  It came from Marni Turkel.  I don't know where she obtained it.  Mine is quite happy and grown easily.

I was given a lovely masdevallia measuriana.  I am unable to find information regarding this specie, although goggle provided a photography of the white flower.  I assume the plant has been renamed and would be grateful  for more information. .

There hasn't been any action on the list in a while so, perhaps someone can help with a couple of questions:

1 - Restrepia chocoensis was known from a single collection for a very long time and - as I understand it - self infertile; I know that a second plant  was purportedly found some time in the recent past. Does anyone know when the second plant was found; if there have been any successful outcrosses with the original, and if so are progeny now available?

2 - What are the morphological distinctions between Trisetella regia and scobina? I do not have access to the green books and am curious.

Hi Dave

here is my contribution to your questions:

Ecuagenera do have R. chocoensis from flasked seeds. whether they're from a succesful selfing, or from an outcross, is a question I can't answer.

The difference between T. scobina & regia lies in the number of calli/keels on the lip. One species has 3, while the other has 4. That's what I read in the Icones. I've both species, and will probably, someday, dissect one flower from each to check if my plants are correctly labelled. In the meantime, I've just harvested pods of scobina x regia. From their distribution maps, it seems they're quite recently isolated populations of a common ancestor.

3 vs. 4 calli?!? hmmm, what is the sample size? Flowers on plant, plants, same plant-different years/culture conditions? How tightly does that correlate with geography? I am extremely skeptical of taxa with very limited ranges/sample-sizes and rather limited differentiation. Recent separation of one person is infraspecific variability of another. I admit, I am a "lumper": unless it is clearly separate, it is the same. I am not afraid of naming species based on very few specimens, or even one: e.g., Depressizona axiosculpta Geiger, 2009, but then the differences must be in your face.

Also, that crosses are possible has two faces: either it is a recent separation, and there still is interfertility. However, evolutionary theory would predict strong separating mechanism (positive Darwinian selection) particularly in sympatric conditions or with secondary contact (positive reinforcement). If the latter view is taken, then the interfertility suggests conspecificity, unless one postulates strong pre-zygotic isolating mechanisms (changes in pollinators; different flowering seasons, ?), but that is a steep hill to climb. Also allopatry and range extension are two explanations of the same observation.

I've been looking at calli in Oberonia with SEM, and there is quite a bit of infraspecific variability. My 2c of rather pleurothallid-ignorant thoughts. I have not seen the green books, and just go off the "3 vs. 4" morsel. I don't want to fault Laurent-the-messenger for it, but I would suggest critical reading of anything that is published.

Best wishes

Daniel

I have no idea of what the sample size was when Luer dissected and described both species (he often based his work on single specimen), but I entirely agree that such closely looking "species", with suxh minor difference, being almost sympatric, could as well be regarded as one single, slightly variable, species! that's why I did cross my 2 plants, I hardly can consider both as different species.
