they fall away together. The species is therefore, among its 
congeners, the counterpart of P. Pringlei in Plagiobothrys.

5. S. HankNESSIL Rough-hirsute, 3—6 inches high, part- 
ed from the base into a few erect or ascending, equal branches: 
lower leaves linear-spatulate, two inches or more in length, 
the floral small, linear-oblong: inflorescence glomerate, be- 
coming racemose here and there : nutlets a line and a quarter 
long, granulate-roughened, carinate on the back and with dis- 
tinct indications of transverse rugæ. 
Near Mono Lake, in the Sierra Nevada, June, 1886, Dr. H. 
W. Harkness. A species quite like S. hispida in its whole 
aspect, but with the nutlets of S. Kingii, except that they are 
interruptedly rugose like those of the Amsinckias. The soft 
earuncular scar is here continued up nearly the whole length 
of the ventral keel, forming a kind of crest upon it. The 
corolla is as large as in S. Kingit, hence quite showy for so 
small a plant of this alliance. 
THe SPECIES OF ZAUSCHNERIA. 
When I look at the strongly marked forms of this genus, as 
they exist in our herbaria—some of them nearly glabrous, 
others heavily villous, some of them hoary with a coarse to- 
mentum, others fairly white with a pubescence so minute as
