Trying to ID an Orchid Collection at Local College - Page 3 - Orchid Board

This may help with the remaining IDs. I've updated the list of the plants in the collection at the beginning of this thread - All marked with a + are labeled. I still need help with the rest.

epiphyte78. I do have a few plants with the wrinkled, smaller pseudobulbs. I'll have to check on the leaves, though they are long and thin.
I haven't seen any thorns on the smooth, clustered pseudobulbs, but then again, I haven't know to look for that. Of course, it could be that that is one of the ones that died or has simply disappeared over the years. Now that the list of plants that haven't been ID'd has shortened a bit, it is fairly obvious that a fair number of the plants on the original list just aren't around any more - we simply don't have that many plants. It's a pity, but it happens. We should have at least half, I think, depending on how many of what is left are duplicates.

You should be able to ID the Coelogyne, Dendrobiums, Ludisia and Lycaste by Googling for images of the plants...their foliage differs sufficiently from the other orchids on your list. A member of your local orchid society should be able to fairly easily point them out for you as well.

Thanks. I'll try that next Wed. when I go in for my weekly inspection/watering/etc.

Thanks epiphyte78. Due to your recommendations I now know that we no longer have Dendrobium kingiannum, Dendrobium loddigesii, Dendrobium oligophylum, or Lycaste ‘Brevispatha’ (L. candida). We do, however, have a Ludisia discolor. I recognized it instantly when I saw the pic - it was with the collection, but I hadn't realized it was a orchid. It isn't like any of the other orchids - pretty fragile in fact. There a four plants that look like they are Coelogynes and four others that are probably divisions of the Encyclia adenocaula, but I really want to wait until they flower before I make any final labels, just in case they are donations that weren't recorded. At least I can label them with the correct genus, though. Yay. Progress!
There is one other plant that I'm not sure if it is even an orchid that was mixed in with the collection. The greenhouse manager said he was told it was an orchid and the general shape looks right-it has small pseudo bulbs sprouting leaves, but the texture is more fleshy than I'm used to with orchids (but then again, there is the Ludisia discolor that is also different). It's blooming now, little tiny white/green bells-not the usual orchid blooms shape, but I was wrong about the Ludisia.... Do any of you have any ideas about this plant? (Thumb included for scale *grin*)

The photos of the plant and it's blooms are in my Gallery (click the camera!) with the titles Mystery.plant and Mystery.bloom. Sorry

That's too bad that you no longer have those Dendrobiums!

I believe the mystery plant is Ledebouria socialis...not an orchid but a fun plant nonetheless.

Yep - a Ledebouria socialis is right. Thanks. As you might guess, the labels in the rest of the greenhouse are just as limited if not downright non-existent as those for the orchids. Ah well. Thanks again epiphyte78.

As FYI, the C. Ruth M. Johnston x C. Brighton has been registered.

It is now C. Watauga according to RHS. I am looking for a photo of it too. It should be white with some yellow in the throat of the column based on the picture I found of one of it's parents.

Sorry to have been gone so long. Not much likes to bloom in 100 degree weather except some Phalaenopsis that already had lables.
shadytrake, thanks for the info on the C. Ruth M. Johnston x C. Brighton. Now I just have to find a picture because I have two similar Cattleyas, both white with heavily ruffled side petals and throat- one with a light yellow throat and the other with a darker, veined gold throat. The lighter one bloomed not long ago, but I was ditzy enough to accidentally delete the photo, so I need to wait for it to bloom again. Eeesh.
I have two new unID'd plants in the photo gallery. One is a labeled Dendrobium Unknown White and the other is Paphiopedium Unknown Small Pink. If anyone is still hanging around this thread, any help would be appreciated!
There is also a photo of a mutant bloom-never seen one with two throats before! It's labeled Phalaenopsis.Dtps. Sin-Yuan Golden Beauty.mutant bloom.
