1. Rhus radicans; caule radicante, foliis 3-foliolatis, foliolis ovato-rotundatis rhomboi- 

 deisve acutis seu acuminatis glabris integris. Linn. Sp. PL p. 381. Hook. Fl. Bor. Am. v. 

 1. p. 127. 



This agrees with specimens from Eastern America, and the R. Toxicodendron is scarcely different from it. 



2. Rhus lobata; caule stricto, ramulis brevibus foliosis, foliis trifoliolatis, foliolis ovatis 

 obtusissimis varie lobatis lobis obtusis sinubus acutis, paniculis laxis petiolo longioribus. 

 Hook. Fl. Bor. Am. v. I. p. 127. t. 46. 



The specimens in the Herbarium differ in no respect from the more northern ones discovered by Mr. 

 Douglas at Fort Vancouver on the Columbia, and figured in the Flora Boreali-Americana. 



Ord. XV. LEGUMINOSiE. Juss. 

 1. Melilotus paniflora. Desv. — De Cand. Prodr. v. 2. p. 187. 



Introduced ? 



1. Trifolium fimhriatum ; prostratum, glabrum, foliolis oblongis subcuneatisve spinuloso- 

 denticulatis, stipulis ovato-acuminatis laciniato-spinulosis, involucro monophyllo laciniato- 

 multifido capitulis subglobosis breviore, dentibus calycinis lato-subulatis rectis corolla 

 subdimidio brevioribus. Hook. — Lindl. in Bot. Reg. t. 1070. Hook. Fl. Bor. Am. v. 1. 

 p. 133. 



1. Medicago denticulata. Willd. — De Cand. Prodr. v. 2. p. 176. 

 Probably introduced from Europe. 



1. Hosackia bicolor; glabra, decumbens, foliolis suboppositis 7-9 oblongis obovatisve, 

 stipulis cordato-ovatis membranaceis obtusissimis, floribus umbellatis, bractea monophylla 

 vel nulla.— Douglas, MSS.—Benth. in Bot. Reg. t. 1257. Hook. Fl. Bor. Am. v. 1. p. 134. 

 — Lotus pinnatus. Hook, in Bot. Mag. t. 2913. 



2. Hosackia decumbens; pubescens, foliolis alternis 3-5 ovali-subcuneatis acutis, stipulis 

 minutissimis acutis deciduis, floribus umbellatis, bractea 1-3-foliolata. — Benth. in Bot. Reg. 

 sub t. 1257. Hook. Fl. Bor. Am. v. 1. p. 134. — Lotus incanus. Douglas, MSS. — ft glabri- 

 uscula; foliolis minoribus siccitate subaeruginoso-viridibus. 



The plant in this Collection differs from the more northern H. decumbens of Mr. Douglas, in the smaller 

 size of the leaflets and flowers, in the less degree of pubescence, and, when dry, in its becoming of an almost 

 aeruginose green colour. In other respects, the two species accord. 



3. Hosackia tomentosa; tota incano-tomentosa, foliolis 5 obovatis acutis, floribus umbel- 

 latis sessilibus, bractea folium simulante. 



This will assuredly rank next to H. decumbens, from which it differs almost solely in the very dense 

 covering of white hairs. Only one specimen exists in the Collection, and that has young fruit, and no 

 flowers. The legumes are short, in proportion to the length of the style. The stigma is not capitate, but 

 simply obtuse, as in Lotus subbipinnatus of Lagasca, and of this work, p. 17. t. 8; which, Mr. Bentham is decid- 

 edly of opinion, should be referred to Hosackia. 



4. Hosackia Purshiana; pubescenti-villosa, foliolis 3 raro-4-5 lato-oblongis, stipulis
