Cischweinfia rostrata - NOT
 

A close relative of trichopilias and sometimes historically subsumed
into that genus, this one is also a small flower and again I haven't
detected a fragrance here either. This was acquired as Cis.rostrata
which itclearly is not. I have not been able to settle on a firm ID; it
does resemble horichii, but I don't think it quite fits there, either.
The flower is 1 1/8" (2.8cm) across, and I can almost detect a fragrance.
