Let's Play "Name That Orchid"!!

[Stasisgate]

We have Onc. ampliatum here in Trinidad and it isn't always bifoliate. I have seen unifoliate plants, the last one in our society's March monthly meeting.

I think the best thing to do now is to wait until the plant flowers, then you'll know for sure (but i really think it's an oncidium too).

1) Onc. ampliatum
2) Catasetinae sp.
3) Maxillaria tenufolia
4) As yet unspecified Vanda sp. (If anyone can figure this one out I could use a replacement.)
5) Onc. sphacelatum

Thanks to everyone who has replied so far. Any links to futher information about any of these plants would be most welcome.

Sorry AaronM...but i have to disagree with No. 2..... i believe it's a grammatophylum. I've got five of em and they all look like that...I also have a few catasetums/mormodes/cycnoches/cycnodes/ etc and their psuedobulbs do no look like that. i will send you pics soon.

Also the Maxillaria (no doubt there) looks like another species that i have seen by a friend of mine who is an orchid judge here in Trinidad and the name he called was not tenuifolia....I will find out for you for sure.

I will be sure to post pictures of all of the above orchids when (and if) they flower. Except number four, it went to the golden greenhouse in the sky. I need to find a replacement for it though, so if it sounds familiar, please give me a name.

O.K. it looks like I am going to have to post additional pictures of number 2 once the new pseudobulbs grow out a bit more. I've looked at pictures of both Grammatophylum and Catasetinae and I've found pictures of both that look very similar to my orchid. Oddly, it's hard to find pictures of old pseudobulbs on the internet. Isn't there a whole subculture of ochid lovers who like to look at pictures of withered, bare, spotty old pseudobulbs?

Thanks for all the help everyone.

Here are pics of old pseudobulbs on my 4 gramms. You can see how similar they are to the mystery plant.

[AaronM]

Do Grammatophylum have huge root masses. The "mystery orchid" would be bigger if it were potted upside down. The bulbs in picture above sure look like what I have. Only mine have brown splotches all over them.
Yes, I know, the splotches aren't supposed to be there.

Thanks all.

Yes they do certainly have huge root masses, and lots of upward pointing roots to trap falling debris that decompose over time and slowly release nutrients.

Hope it helped. I really think it's a grammatophylum though.
