Nephrangis bertauxiana Szlach. & Olszewski, in Fl. Cameroun 36: 696 (2001).
Nephrangis filiformis var. bertauxiana (Szlach. & Olszewski) R.Rice, Prelim. Checklist & Survey Subtrib. Aerangidinae (Orchidac.): 40 (2005).
This species was described in 2001 from Gabon and is known only from the type collection. It was flowering in October and is easily distinguished from Nephrangis filiformis by the slightly larger, pendent flowers and especially by the longer spur that has a distinct knee-bend about halfway along its length where it suddenly becomes narrower.
The species is named in honour of Pierre Bertaux, conservator of the living collection of orchids in the Jardin du Luxembourg, in Paris.
In woodland trees on branches at elevations of 1500 meters.
As given for the genus, cool growing epiphyte.
