fills, one-seeded, subglobose, but with 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 differ 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. 



I. Astragalus (§ Ciceroideae) ervoides; puberulus, caulegracili elongato ramoso, foliolis 

 15-17 remotis lineari-oblongis obtusis, stipulis lanceolatis parvis, pedunculis axillaribus 

 folio Jongioribus racemosis, racemis 10-12-floris, calyce brevi-ovato oblique obtuse 5- 

 dentato dentibus brevibus subasqualibus (pedicellisque) nigris, corolla (flava) calycem 

 subduplo superante, leguminibus Jinearibus 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 heterophyllum ; erectum hirsutum, foliis simplicibus late ovatis obtusis 

 supremis trifoliolatis, foliolis ovatis intermedio duplo triplove majore, stipulis bracteisque 

 acuminatis 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 simple, 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 — 0. 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.
