Pleurothallis sp. ID

It looks very familiar. I know I don't have it, but I am checking some resources.

 

It's probably Pleurothallis/Muscarella aristata--the petals aren't sufficiently visible, but the rest certainly looks correct, especially the dark, bulbous apex of the lip formed by revolute sides that I believe I see. The shape of the petals looks good--are they ciliate? If yes, that's a nudge closer to P. aristata.

 

The sepals (the three more or less triangular things with tails) are translucent yellow, variably marked with purple, mostly along the veins, sometimes the entire blade will be suffused with the darker pigment, sometimes more heavily, sometimes less, sometimes not at all. Color is one of the less reliable discriminators here. Your photos show a translucent yellow dorsal sepal (the top triangle with the tail) with the central vein marked with purple. Morphology is more reliable than color in these little guys, and many photos must be viewed with skepticism.

 

well said and I concur.

 

No, I would not call it "af." or "cf." Both of those terms have a technical meaning. Your photos don't share enough detail for a definitive diagnosis, it's hard with these teeny things, but it sure looks like Pleurothallis aristata from what I see (but I cannot see enough). Suggestion: find a diagnostic drawing of Pleurothallis aristata, pull out a hand lens, and enjoy the wonders of seeing the detail in this little thing. In particular, you want to pay attention to the lip (the dark thing that sticks out between the lateral sepals, the paired triangular things on the bottom) and the petals, which are the two smaller things on either side of the dorsal sepal (the triangular thing on top). Warning: this is how it starts--you may fall in love and become a pleurothallidiot for life.
