Unusual Vandaceous Species NOID Cleisostoma?

[unhappykat]

Hello All,

I need a little help in finding the identification of this vandaceous species I acquired a while back. The closest genus placement I have come up with is Cleisostoma, but there are several other genera that it may easily fit into.

The mother plant that the division was taken from was 5 feet in length with leaves reaching 10+ inches. The foliage is dark maroon in color and the growth habit is sharply pendulous. The flowers are roughly 3/8 inch across individually and the mature clusters hold 50+ on a pendulous, branching inflorescence.

The photos are of my division on its blooming cycle, I tried to take the closest photos of the bloom I could but my camera's macro is limited.

Any help in identification would be appreciated.

Boy, I tried.....I have scanned a lot of my reference material for the last hour or so, thinking I had seen it, but to no avail. I think you are on the right track, but I wasn't able to pin the name on it for you - If I do find the photo I was thinking of, I will let you know.
Sorry I didn't have better new, but as I say - I tried!!
Whatever it is, it is happy! Very nice looking plant.

Do you have a close up pic (at least closer) of the blooms? Try shooting through a magnifying glass or even a magnifying mirror.

One possibility is the Cleisostoma nangongense based on bloom colors but can't make out the details on your pics. IOSPE seems iffy on the description on this one.

Another might be a Cleisostoma rolfeanum.

Thank you both for your efforts. I will keep searching through my references and try to locate some additional references on the cleisostoma genus when able.

AnonYMouse: at the time of the blooming I did not have a way to magnify the blooms past what is there. I do see evidence of another spike emerging on the plant and I will check with the original source to see if the mother plant is in bloom again, hopefully I can take a few blooms under a stereoscope and get a better magnification of the lip and column.

Nope. This is Luisia teretifolia




The blooms emerge along the growths rather than sending out a long spike. And, the "leaves" and growth habit are different. This plant is more succulent in appearance.

I would say you are on the right path w/the Cleisostoma. Any chance the person you got it from can help w/the ID?

At this time the original owner only knows that the plant was left from a boarding customer many years ago. I will be inspecting the original mother plant on my next trip to the collection, really hoping for it to be in bloom again.

I think you may have Cleisostoma williamsonii. There are colour variations of which I suspect yours is one....then again I may be horribly wrong!!

Good luck.
