Pleurothallis densifolia Rolfe (1895: 260) .

Type: — BOLIVIA: Yungas, 1890, M. Bang 216 [lectotype, here designated: GH-74200 !; isolectotypes: BR-6585990! , MICH-1655586! MO-1183156 ! ( Figure 10 View FIGURE 10 ), NY-9225! , NY-9226! , PH-00030689 ! PH-00030690! , US-00093632 ] .

Taxonomic discussion:— In the protologue, Rolfe (1895) mentioned Miguel Bang’s collection number 216. However, since this collection has several syntypes housed in different herbaria, it is necessary to designate a lectotype and some isolectotypes, as proposed above.

According to Rolfe (1895) S. densifolia is characterized by its densely caespitose habit with abbreviated stems; linear-oblanceolate, rounded leaves that gradually tapering toward the base into a petiole indistinguishable from the lamina; racemose inflorescence, up to 2.5 times longer than the leaf; peduncle longer than the leaf, somewhat zig-zag rachis; with up to 9 distichous, simultaneous yellow, concolorous flowers, ascendent; pedicels spaced along the rachis and longer than both the flower and ovary combined; dorsal sepal ovate-lanceolate, acuminate-caudate; the lateral sepals fully fused, similar in shape to the dorsal but longer; petals obovate-oblong, obtuse and lip oblong, obtuse; column smaller than the petals.

Distribution:— Bolivia.
