This exactly agrees with our original specimen of Trigonella Americana, received from Mr. Nuttall, except 

 that the leaflets are rather shorter in proportion to their breadth. There is, however, nothing silky about the 

 plant in its dried state, as Pursh's name would seem to imply : it is clothed with soft and short patent hairs, 

 which give no glossiness to the stems or foliage, and which are best seen when the plant is held up between 

 the eye and the light. In the greater number of its leaflets, this species differs from H. unifolwlata, a.., and 

 in the larger flowers and seed-vessels. 



1. Phaca densifolia; caule decumbente ramoso glabro, stipulis ovatis acuminatis, foliis 

 14-16-jugis subtus rachique villoso-tomentosis, foliolis oblongo-ovalibus emarginatis, ped- 

 unculis calycibusque villosis, racemo multifloro compacto, legumine membranaceo ovato 

 maximo inflate- glabriusculo reticulate — Sm. in Bees' Cycl. — De Cand. Prodr. v. 2. p. 274. 



The legumes of this very fine species of Phaca, which was first found by Mr. Menzies in California, are 

 remarkably large, inflated and membranaceous; in these respects, exactly resembling those of Phaca inflata, 

 of Dr. Gillies (in Bot. Misc. ined.), from Uspallata in South America. The habit of the two species is like- 

 wise very similar ; but, in Dr. Gillies', the whole plant is glabrous, and the flowers are much smaller. 



2. Lathyrus decaphyllus; glaber vel pubescens, foliolis 4-6-jugis ellipticis rarius ovatis 

 vel suboblongis, stipulis parvis semisagittatis lanceolatis lobo deflexo stipulam subsequante, 

 pedunculis folii longitudine multifloris, calyce pubescente dentibus duobus superioribus 

 valde abbreviatis, (corollis purpureis,) leguminibus lineari-oblongis compressis. Hook. — 

 Pursh, Fl. Am. v. 2. p. 471. Hook. Fl. Bor. Am. v. 1. p. 160, et in Bot. Mag. t. 3123. — 

 /3. minor ; foliolis minoribus angustioribus. 



This appears to be a very variable plant, and the specimens in the Collection have the leaflets smaller 

 and narrower than is the case with the plant figured in the Bot. Mag. ; but not more so than in some speci- 

 mens from the Columbia, gathered by Mr. Douglas. 



1. Lupinus polyphyllus. Lindl. in Bot. Reg. t. 1097. — L. Chamissonis. Eschscholtz, in 

 Linncea, v. 3. p. 151 ? 



We cannot be mistaken in this plant, although only a single leaf exists in the Collection. 



2. Lupinus macrocarpus; suffruticosus, foliosus, foliis subbrevi-petiolatis septenis, foliolis 

 lanceolatis obtusissimis inferne attenuatis supra glabris subtus appresso-pubescenti-sericeis, 

 racemo multifloro, floribus (inter maximos) raro verticillatis, calycibus pedicellis rachique 

 appresso-sericeis, leguminibus lineari-oblongis tumidis hirsutis 8-10-spermis. 



Found by Mr. Menzies during the voyage with Captain Vancouver, and probably common about San 

 Francisco ; yet it does not correspond with any described species, nor with any found by Mr. Douglas. The 

 lower part of the stem is decidedly shrubby, the leaves and legumes large in proportion to the size of the 

 plant, apparently yellow when recent. Perhaps, in habit, its nearest affinity is with L. littoralis, Dougl., but 

 the leaves are, in that plant, silky on both sides, the flowers are differently coloured, and the legumes are not 

 half the size. 



3. Lupinus sericeus; fruticosus, ubique pulcherrime appresso-sericeus aureo-nitens, caule 

 valde folioso, foliis breviter petiolatis septenis, foliolis lanceolatis acutis inferne attenuatis,
