Lupinus Guadalupensis. 



Animal, near L. nanus, but stouter and more villous : stem 

 a foot or two high, branching from about the middle: leaf- 

 lets 7—9, oblanceolate, an inch long, villous on both sides : 

 petioles three inches long: bracts much exceeding the calyx: 

 upper calyx-lip 2-cleft: corolla a half inch long, bluish-pur- 

 ple: pod two inches long, 6 — 8-seeded. 



High plateau of Guadalupe Island, in good fruit, but 

 nearly past flowering the 23d of April. A coarser plant than 

 L. nanus, with shorter branches, none of them from the 

 base of the stem. 



Lupinus Ludovicianus. 



Suffrutescent, stout, branching, a foot or two high : very 

 villous-hirsute on the branches and petioles, and through- 

 out, even to the bracts, calyx and legume densely white-tom- 

 entose: petioles stout, firmly erect, 2—3 inches long: leaf- 

 lets 7 — 9, broadly oblanceolate, obtuse, 8—10 lines long: 

 flowers purple, of medium size, subverticillate, in a short- 

 peduncled, rather dense raceme: bracts short: calyx-lips 

 sub-equal, broad, entire: keel strongly falcate, surpassing 

 the other petals, somewhat woolly-ciliolate : pod an inch 

 long, 5-seeded. 



Mountains above San Luis Obispo, July, 1885; Mrs. Cur- 

 ran. The species is nearest L. niveus of Guadalupe Island, 

 but has pubescence of a very different character, and is, 

 moreover, a stouter, less graceful plant. 



Hosackia (Euhosackia) argyraea. 



Densely appressed-silky : stems numerous from a perennial 

 root, rigid and nearly prostrate: stipular glands small, hid- 

 den by tufts of white hair : leaflets a half inch or less long, 

 oblong-obovate, very obtuse, about five on a well developed, 

 broad rachis: peduncles an inch long, about 2-flowered: 

 calyx-teeth broadly lanceolate, half the length of the tube:
