334 CALIFORNIA.— SUPPLEMENT. {Leguminosce. 



3. P. Douglasii; decumbens elongata glabra, caule striate, foliolis fere semper oppo- 

 sitis 12-14-jugis oblongis obtusis subapiculatis subsessilibus, pari inferiore remote, stipulis 

 ovatis acutis membranaceis, pedunculis folio longioribus, racemo plurifloro laxo ovali- 

 oblongo, bracteis pedicellum brevissimum superantibus, calycis villosuli dentibus lato- 

 subulatis brevibus rectis subasqualibus albo-ciliatis, legumine (unciali) ovali-oblongo 

 acute inflate Torr. et Gr. Fl. I. p. 346. 



Apparently a straggling- plant, 1£ or 2 feet long, glabrous in every part, except the calyx and the ovary, 

 though the hairs almost disappear on the fully formed legumes. 



4. P. densiflora ; decumbens subincano-pubescens, caule striate, foliolis 16-18-jugis 

 densis obovato-cuneatis retusis, stipulis connatis ovatis acuminatis membranaceis, pedun- 

 culis folio longioribus, racemis ovatis demum reflexis densifloris, bracteis parvis subulatis 

 pedicellum aequantibus, calycis tubo brevi dentibus lato-subulatis brevibus rectis sub- 

 asqualibus, legumine maximo subbiunciali elliptico acute inflato.-^Sm. in Rees' Cycl. —

 Gr. Fl. ]. p. 344. — P. canescens. Nutt. in Torr. et Gr. 1. p. 344. 



A straggling plant, slightly hoary with down. The leaves and leaflets crowded. 



5. P. astragalina. De Cand. — /3. foliolis floribusque minoribus. 



We have compared what we have here considered a slight variety of P. astragalina, with the common 

 alpine and arctic state of the plant, and can find no difference, except in the smaller and slenderer flowers and 

 leaflets. California, however, must undoubtedly be considered a very southern station for it. It is scarcely 

 distinguishable from P. debilis, Nutt., but that is a Rocky Mountain and not a coast plant. 



1. Astragalus Hypoglottis. L. — A. goniatus. Nutt. in Torr. et Gr. Fl. I.jp. 330. 



Hab. Pine Creek, Snake Country. (Tolmie.) — Mr Nuttall's A. goniatus, from the Rocky Mountains, 

 N. California, is precisely the same. 



2. A. glareosus. Dougl. in Hook. Fl. Bor. Am. 1. p. 152. Torr. et Gr. FL 1. p. 333. 

 — A. argophyllus. Nutt. in Torr. et Gr. Fl. \. p. 331 (excl. the synonym). 



Hab. About Snake Fort, Snake Country. (Tolmie.) — Mr Nuttall had considered his A. argophyllus as 

 probably the same as the A. melanocarpus of Dr Richardson ; but on a comparison of specimens, we find 

 that not to be the case. The argophyllus is identical with the A. glareosus of Douglas. 



3. A. didymocarpus ; suberectus pilosiusculus, foliolis sub-8-jugis oblongo-subobo'vatis 

 emarginatis, stipulis parvis ovatis membranaceis ad basin petioli subconnatis, pedunculis 

 folio longioribus, floribus capitatis parvis, calycis hirsuti dentibus subulatis rectis longi- 

 tudine tubi, leguminibus coriaceis didymis rugoso-venosis lobis monospermis. (Tab. 

 LXXXI.) 



This is a very remarkable species, especially in the structure of its legumes. These are obovate, laterally 

 compressed, strongly nerved and wrinkled, with the introflexed margins (from beneath) reaching nearly to 

 the back, so as to divide them into two compressed one-seeded lobes.

 they easily separate into two 1 -seeded portions ; fig. 7. Seed ; — magnified.
