This orchid grows in soil, on rocks, or on tree trunks in limestone habitat types. It produces 4 to 6 linear green leaves up to 19 centimeters long. It blooms in a single flower on a hairy brownish stalk. The flower is up to 8 centimeters wide. The dorsal sepal is white with a greenish or brownish spot at the base. The synsepal is pale green and the petals are brownish with pale edges. The staminode is yellow.[2]

This species is pollinated by hoverflies, in particular Allograpta javana and Episyrphus balteatus.[3]

gollark: Bad things? So don't do that, silly.
gollark: The mobile app supports no commands.
gollark: A search query which returns lots of results is going to take longer than one which returns none, mostly, thus you have access to some data you shouldn't.
gollark: For example, send a request to `https://interweb.site/search-some-private-data?query=thing` using a form or `img` or `script` or whatever, and see how long it takes (using `onload`/`onerror` handlers and such).
gollark: The timing attacks thing: since you can send GET requests to domains you probably shouldn't be able to, and time how long they take, you can infer some data you shouldn't be able to from other domains.
