112 Mr. Brown’s Observations on the 
troduced some additional distinctions into the following charac- 
ter of 
SALMEA. | 
Decandolle in Cat. Hort. Monspel. p. 140. 
Involucrum imbricatum. | Receptaculum conicum, paleis persisten- 
tibus. Flosculi tubulosi, uniformes, hermaphroditi (5-fidi). An- 
there sagittate. Achenium verticaliter com pressym, bi-arista 
tum ; aristis persistentibus (apteris v. alatis). — 
Frutices (Americæ æquinoctialis) sepius decumbentes. Folia op- 
posita, indivisa. Inflorescentia terminalis, subpaniculata, vel corym- 
bosa. Corolle albide. Paleæ receptaculi post lapsum pericarpiorum 
persistentes. 
Oss. 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. | t | 
.. 1. Salmea scandens, (Decand.l. c.) in which the aristæ are equal 
and without any membranaceous border: stigmata remarkably 
dilated, tongue-shaped, obtuse, not hispid, obscurely papulose, 
and apparently withont any terminal appendix: style dilated at 
the base into a hemispherical bulb which is truncated underneath. 
2. Salmea hirsuta, (Decand. |. c.) whose aristæ 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 
ofthe 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:
