Type : perennial herb, frequent in deep humus at base of rocks, summit of 

 upper east-facing escarpment of Mt. Ebeni. elev. 700 m, British Guiana, Oct 15, 

 1951, Bassett Maguire 12119 (XY). 



None of the other known species of Salpingo, lias a paleaceous indument. In 

 fruit shape, 8. paleacea is intermediate between the southeast Brazilian species 

 (with trigonous fruit) and the remainder of the genus (with long hypanthia). 

 The stamens resemble those of 8. secvmda Schr. & Mart, ex DC. and 8. maguirei 

 Gleason (and probably 8. ciliata Pilger) in having a very minute basal spur on 

 the connective rather than the prominent spur pictured by Triana (Trans. Linn. 

 Soc 28: pi. 6, f. 80. 1871) for 8. margaritacea (Naud.) Tr. and S. longifolia 

 • Cham.) Tr. The habit of S. paleacea is rather reminiscent of that of Tococa 

 platyphylla Benth.
