23. Vanilla pfaviana Rchb. f. (Reichenbach 1883: 230)

Type.

COSTA RICA • “ Mexico ”; R. Pfau 269; holotype: W!, AMES! [00090736] sketch, K! [K 001784688] photograph .

Notes.

The paper in which Reichenbach published this species explicitly states he is basing it solely on a sketch received from Pfau (Reichenbach 1883). There is a single sketch in his herbarium matching the protologue, and it is determined as ‘ Pfaviana’ in the author’s own handwriting. We find this sufficient to unambiguously determine it as the holotype.
