Salmea.

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? curviflora (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:
