Can someone identify this Dwarf Wild Orchid?

[Ephemere]

This is a dwarf wild orchid which grows in the limestone soil of the jungles in tropical Southern Thailand. The flowers are absolutely TINY in comparison to the bulb as they measure less than 1/2 inch in diameter. I am attaching photos of the whole plant and blooms. Know it ? Thanks for any info.!

Cheers, Michael

Hi Michael.

I'm only floating this out there as I have a plant with a similar bulb structure, so please don't think I know what I'm talking about.

Disclaimer aside, the bulbs look quite a lot like those on my Phaius. And I note there's a Phaius indigoferus that's indigenous to Thailand...

The pictured plant doesn't look very healthy which may explain the lack of leaves while it's flowering.

That's my stab in the dark. Hope someone else can be of more assistance.

Cheers,
Aus.

It's a Eulophia, I'm not sure exactly what species.

Graminea?

Many Thanks!

Eulophia graminea was my first guess, based on the look of the flowers, but that species should have flowers at least twice that size. (I would guess 1 inch minimum) it should also have leaves when it's blooming.

Eulophia andamanensis flowers from leafless,10cm p'bulbs on 30cm stem,flowers to 15mm in size, native to lowland Indochina rainforests. Nice find. Brad

nice guess, Brad, but andamanensis does not have hairs on the lip, and the lip is normally white with red or brown veins.

Right you are,Kip.One of my main resources,'Botanicas Orchids',has small pictures making it hard to pick up detail sometimes.Sooo...will refer to other sources for Eul. with deciduous blooming p'bulbs.I love a good puzzler. Brad
