of the Californian coast. This species, like the Stlene, has been 

 compared with tlie P^uropean material at Kew through the kindness 

 of I'rof. Oliver and Mr. Baker. It differs from T. saxalile in the 

 more unequal nodes of the stem, the more dentate and not bifidly 

 eraarginate leaflets, and the more coriaceous calyx with longer and 

 more rigid teeth. 



Astragalus (Homalobus) Foravoodii, Annual, the several 

 ascending stems about a foot high, sparsely covered with a fine pubes- 

 cence : leaflets 5 or 6 pairs, linear to linear-oblong, 6 to 9 lines long : 

 peduncles exceeding the leaves, bearing short loose racemes of small 

 (4 or 5 lines long) deflexed flowers ; calyx campanulate, the narrow 

 teeth nearly equalling the tube ; corolla whitish with a dark purple 

 keel : pods deflexed, long-stipitate, thin-coriaceous, flattened, the 

 ventral suture straight and the dorsal much curved, 9 to 12 lines 

 long. — Black Hills of S. Dakotah, in dry rocky places in creek 

 bottoms; Dr. W. H. Forwood, U. S. A., May, 1887. Near A. steno- 

 pht/Ibis, Torr. & Gray (A. flipes, Torr.). 



ViciA Thurberi. Annual, about a foot high, the young leaves, 

 etc., pubescent, becoming glabrous: leaflets 4 to 12, narrowly linear, 

 acute, 3 to 7 lines long ; stipules small, subulate-lanceolate or linear, 

 not at all sagittate, entire : peduncles short (3 to 6 lines long), bear- 

 ing one or rarely two small white or purplish flowers : calyx nearly 

 glabrous, the teeth rather short-acuminate : pods glabrous, sessile, 

 oblong, obliquely acute at each end, about 9 lines long by 2}j or 3 

 broad, 5-7-ovuled. — From southern Utah and Colorado to Arizona 

 and New Mexico; collected by Thurber (n. 150 and 299), Wright 

 (n. 1350), Parry (n. 33, of 1874), Lemmon (n. 50, of 1880), Bran- 

 degee, etc., and referred to the Californian V. exigua, Nutt. That 

 species is a taller plant, with similar foliage and fruit, but the stipules 

 narrowly semi-sagittate and the more slender peduncles (1 to 2 inches 

 long) usually 2-3-flowered, the flowers approximate. The only Nut- 

 tallian specimen of V. exigua in the Gray Herbarium was collected 

 by Gambel on Catalina Island, and is the same as others collected 

 by Coulter, Samuels, Thurber (San Diego), Bolander (Los Angeles), 

 and M. E. Jones (Encenada, Lower California). The original descrip- 

 tion in Torrey & Gray's Flora seems to include also the next species. 



ViciA Hassei. Often tall: leaflets 3 to G pairs, linear to narrowly 

 oblong, acute or obtuse and apiculate, or more frequently truncate 

 and emarginate or toothed at the apex; stipules semi-sagittate with 

 the rather broad lower lobe usually 2-4-toothed : peduncles 6 to 15 

 lines long, 1-flowered or sometimes remotely 2-flowered : pod moro
