摘要：
A new species of Gesneriaceae (tribe Gloxinieae) is described from Ecuador and Peru in South America. Pearcea pileifolia J. L. Clark & L. E. Skog is vegetatively distinctive from all other species of Pearcea Regel by its oblong leaf blades with crenate to serrate margins and markedly anisophyllous, opposite leaves with the smaller leaf in a pair reduced to a scalelike appendage. Observations of the bivalved fruit dehiscence and the resulting appearance of winged appendages in P. pileifolia and other congeners are discussed.
