 whence the name 



10. P. neglecta. — The specimen of Astragalus Canadensis in the Lin- 

 nasan herbarium marked ' H. U.' (Hortus Upsalensis) belongs to Phaca 

 neglecta ; but the specimens from Kalm are the proper A. Canadensis. 



11. P. astragalina.—T\ie Californian plant which we have alluded to 

 under Astragalus leptocarpus, is considered by Hooker (Z. c.) as a variety of 

 P. astragalina, with smaller flowers and leaflets ; but it will perhaps prove 

 to be different when the fruit is known. 



12. P. elegans (Hook. !) — P. parviflora, Nutt. does not differ from this. 



14. P. Ahoriginorum (Hook.), the Astragalus Aboriginorum of Richard- 

 son, should have been A. ahoriginum. We had inadvertently adopted the , 

 name as given by Richardson without observing the grammatical error. 



20. P. podocarpa (Hook. !) — Stem flexuous, rather rigid. Petioles rigid 

 and somewhat persistent. Legumes when mature arcuate-curved, tumid ; 

 but the younger ones are quite flat as described. — A very singular species, 

 which connects Phaca with Homalobus, if indeed it should not be referred to 

 the second section of that genus ; but the mature legumes are very tumid. 



• 23. P. parviflora (Nutt.) is P. elegans, Hook. 



26 (a). P. macrodon (Hook. & Arn.) : erect, densely canescent-pubescent, 

 at length rather glabrous; stem angled ; leaflets 11-13 pairs, oblong-lanceo- 

 late, obtuse, apiculate, very slightly petiolulate ; stipules small, lanceolate, 

 acuminate, persistent ; peduncles rather shorter than the leaves ; racemes 

 elongated, many-flowered ; bracts subulate, membranaceous, as long as the 

 pedicels ; tube of the calyx oval ; the teeth filiform-subulate, flexuous, as 

 long as the tube, rather shorter than the corolla. — Hook. 4* Am. ! hot. 

 Beechey, svppl. p. 333. 



California, Douglas! — A tall species. Leaves 6 inches long. Flowers 

 apparently yellow, at first spreading, then reflexed ; the corolla a good deal 

 curved upwards. Calyx with singularly long and flexuous narrow teeth. 

 Ovary linear, compressed, silky. Hook. S^ Am. 



26 (h). P. leucophylla (Hook. & Arn. 1. c), our Astragalus leucophyllus, 

 p. 336, is more probably a Phaca. We have a nearly allied species, if not 

 the same, from Oregon, in fruit only ; with ovoid, pointed, thick and coria- 

 ceous legumes.
