carpels strongly veined. — From San Benito Island, off the coast of 

 Lower California ; collected by Dr. T. H. Streets, U. S. N., December, 

 1875. This is the fourth species of the genus that has been found on 

 the small islands near the southern coast of California, and is peculiar 

 in the prominent veins upon the sides of the carpels. 



Malvastrum Palmeri. A stout perennial, densely stellate- 

 pubescent and -hirsute : leaves broadly ovate, 2 or 3 inches long, some- 

 what 3-o-lobed, the lobes obtusish, crenately toothed ; stipules conspic- 

 uous, broadly lanceolate, acuminate, nearly half an inch long: floral 

 bracts large and conspicuous : flowers nearly sessile, in terminal clus- 

 ters, large (1^ inches broad), yellowish rose-color: bractlets linear- 

 lanceolate, 8 to 10 lines long, nearly equalling the acuminate calyx- 

 lobes : carpels rounded, somewhat pubescent. — At Cambra in South- 

 ern California, a mile from the sea-beach ; collected by Dr. E. Palmer 

 (n. 50 of his distribution), July, 1876. Marked by its stout leafy 

 habit and by its large floral bracts and calyx. 



LuPiNUS TRIFIDUS, Torrey in hei'b. Very closely resembling L. 

 micranthus, but the lower lip deeply 3-cleft with linear segments : pod 

 narrower and shorter (about 6 lines long and \\ broad), usually 5-6- 

 seeded : seeds a line broad, uniformly mottled : flowers 3 lines long 

 or less, mostly in a single terminal whorl. — L. micranthus, var. trijidus, 

 Watson, Rev. Lup. 535. Near Sau Francisco, by various collectors, 

 and recently in fine specimens by Mr. G. R. Vasey. The ordinary 

 L. micrant/ms, besides the nearly entire lip. has a pod often an inch 

 long and 2k lines broad, 6-9-seeded, and the larger seeds variously 

 mottled, but with a lighter spot around the sometimes dark eye. 



LuPiNUS Arizonicus. Annual, slender, erect, a foot high or less, 

 villous throughout with scattered spreading hairs : leaflets 6 to 8, shorter 

 than the slender petioles, linear-oblanceolate, obtuse or acute, a half to 

 an inch long: flowers scattered in loose racemes; bracts long and some- 

 what persistent: calyx rather broad at base, the lower lip trifid: petals 

 4 or 5 lines long, deep purplish blue or sometimes ochroleucous, the 

 broad wings (2| lines wide) exceeding the orbicular standard : pod 6 

 to 9 lines long, 3-6-seeded : seeds rounded, compressed, with prominent 

 sides and rather thin margin, 1 ^ lines broad, nearly white. — L. concin- 

 mis, var. (?) Arizonicus, Watson, Rev. Lup. 537. In Arizona and 

 South-eastern California. The typical L. concinnus, Agh., is much 

 more densely villous, lower and of more diffuse habit ; leaflets broader ; 

 calyx narrow at base, and flowers narrower (wings \\ lines broad, and 

 standard elliptical), the petals usually becoming reddish purple, or the 

 standard yellowish : pods 3-4-seeded, but seeds similar.
