12. L. g-raiidittorus, Greene, 1. c. ; Benth. Trans. Linn. Soc. xvii. 366 

 ( 1837), under Jlosackia. TaU, slender with few leaves and long inter- 

 nodes, nearly glabrous : peduncles slender, elongated, small-bracted, 

 5 8-flowered : fl. nearly 1 in. long, deep yellow, the petals broader than 

 in the last, turning orange. Same range as the last ; but less frequent. 



13. L. iiiacraiithas, Greene, 1. c, also in Bull. Calif. Acad. i. 81 (1885), 

 under Ilomckia. Stoutish, 1 ft. high, silky-puberulent : leaflets 7 — 9, 

 obovate or oblong, obtuse, % — 1 in. long ; stipules minute, subulate, 

 caducous, leaving a dark gland-like permanent base : peduncles 2 — 4 in. 

 long, 3 7-flowered ; bract ] -f oliolate : corolla 1 in. long, bright yellow, 

 the banner ^ in- broad : pod stout, 1% in. long. — El Dorado Co., on 

 Sweetwater Creek, Mrs. Cvrran. The young specimens, on account of 

 their manifest stipules, would be referred to the next group ; the older 

 ones, showing only the dot-like traces of them would place the species 

 here ; but on the whole, it is a link connecting the two groups.

 tributed ; flowers in bracled umbels ; pods long, straight, tardily 

 dehiscent. — Types of Genus Hosackia, Benth.
