The foliage of Plocoglottis Wenzelii resembles that of P. luc- 



banensis Ames and P. bicallosum Ames. From the former species 



it is in part easily distinguished by the looser inflorescence, the 



flowers of P. lucbanensis being crowded in an abbreviated raceme. 



From P. bicallosum, P. Wenzelii is distinguishable by means of 



its smaller flowers, very different labellum, and narrower leaves. 



P. mindorensis Ames is a near ally, but differs in the foliage.

 ters above sea level in forest of the foothills. Flower white, yellow, and
