Obs. Of this genus I have examined specimens of three species 

 in Sir Joseph Banks's Herbarium, differing from each other in 

 several very remarkable characters. 



1. Salmea scandens, (Decand. 1. c.) in which the aristae are equal 

 and without any membranaceous border: stigmata remarkably 

 dilated, tongue-shaped, obtuse, not hispid, obscurely papulose, 

 and apparently without any terminal appendix: style dilated at 

 the base into a hemispherical bulb which is truncated underneath. 



2. Salmea hirsuta, (Decand. 1. c.) whose aristae are unequal ; 

 the inner, which is the larger, being furnished with an evident 

 ala; the outer having a narrow margin only: stigmata sharp and 

 spreading : style dilated into an ovate bulb which has an attenuated 

 base. 



3. Salmea? curvifiora (nob.) differs from both the preceding in 

 the tube of its corolla being remarkably bent outwards. In place 

 of the inner arista there is a broad obtuse wing, of which the in- 

 ner margin is straight and thickened, the outer continued down 

 nearly to the base of the pericarpium : the outer arista is winged :
