fills, one-seeded, subglobose, but witb the top coming to a sharp truncated edge. The bracteas are mem- 
branaceous and exhibit no glands. The plant seems to be entirely herbaceous ; and, as far as can be perceived 
from the withered remains of its flowers, these are white or cream-coloured. 
3. D. elegans ? Hook, et Am. Bot. of S. Am. in Bot. Misc. v. 3. p. 183. 
Hab. Tepic. — The single specimen is in an imperfect state ; but, so far as we can judge, it seems scarcely 
to diff'er from our D. elegans from the El Cerro del Morro in the province of San Luis, S. America. The 
flowers are, however, smaller, but of the same colour; and less injured specimens would, in all probability, 
present important distinguishing characters. 
1. Astragalus (§ Ciceroidese) ervoides; puberulus, caule gracili elongate ratnoso, foliolis 
15-17 remotis lineari-oblongis obtusis, stipulis lanceolatis parvis, peclunculis axillaribus 
folio longioribus racemosis, racemis 10-12"floris, calyce brevi-ovato oblique obtuse 5- 
dentato dentibus brevibus subtequalibus (pedicellisque) nigris, corolla (flava) calycem 
subduplo superante, leguminibus linearibus deflexis curvatis acutis glabris. 
Hab. San Bias to Tepic. — Our portions of this plant measure less than a foot, slender, they are branched 
and straggling, herbaceous. Leaflets about half an inch long. Flowers of the same length, soon reflexed. The 
short cup-shaped calyx, with its obliquely 5-toothed mouth, has a few dark-coloured short hairs scattered over 
the' surface, yet so as scarcely to affect the greenish, colour ; but the short teeth and the pedicels are quite 
black. 
1. Stylosanthes Guianensis, Sw. — De Cand. Prodr. 2. p. 318. Benth. in Ann. of Nat. 
Hist. 2. p. 434. 
Hab. Realejo. — A tall growing plant, with rather large, lanceolate leaflets, acuminate at both extremities. 
Flowers collected into large, dense capitula which are clothed with long spreading fulvous hairs. The same 
species is common in Brazil and Peru, as well as in Guiana. 
1. Desmodium heteropliyllnm ; erectum hirsutum, folds simplicibus late ovatis obtusis 
supremis trifoliolatis, foliolis ovatis interniedio duplo triplove majore, stipulis bracteisque 
acurainatis rigidis striatis. 
Hab. Realejo. — There is no fruit on the solitary specimen, nor any perfect flowers ; but the foliage is 
unlike any with which we are acquainted. The leaves are in general sinqjle, 2 or more inches long, on 
slender petioles about an inch long, with a pair of small stipules near the summit ; the uppermost leaves are 
much smaller and trifoliolate. 
2. D. incanum, Sw. [sub Hedys.) Macfad. Jam. I. p. 265 /3. supinum. — D. supinum, 
Sw. DC. 
Hab. /3. Realejo. — This is a common plant in Jamaica, and I possess the same from Mr Cuming (his n. 
1023) ; and Dr Macfadyen has clearly shown that D. supinum is only a variety of D. incanum, produced 
by weakness.
