D. Andersonii 1s )). M/enzieszi Watson |. c., asto Nevada 
plant, and mainly D. decorum var. Nevadense of the Botany 
of California. It belongs to the mountains of W. Nevada 
and the adjacent Sierra Nevada. More specimens in fruit 
are desirable. 
*D. Parryi is founded on specimens collected in San Ber- 
nardino Co., California, by Parry in 1850, Parry and Lem- 
mon in 1876, and by Parish; also apparently the same col- 
lected near Santa Barbara by Brewer. 
‘D. Parishii is a rather low and rigid-stemmed species, 
much smaller-flowered than the preceding, collected at Agua 
Caliente, on the southeastern borders of California, by Par- 
ish, and in adjacent Lower California by Orcutt. 
D. hesperium is a common Californian species, which 
has passed for D. simflex and for Californian D. azureum. 
It appears to abound from Mariposa Co. and from Monterey 
northward, and it reaches W. Oregon. The roots of this 
and the next species are intermediate in character between 
the merely fasciculate and the tuberiform types, but rather of 
the former. 
D. variegatum Torr. & Gray is very well marked in» 
character, and is one of the most showy species. Bentham, 
in Pl. Hartw. 295, took it for D. decorum, but wrongly. We 
know it only in California, from Monterey to the Upper Sac- 
ramento Valley. 
he remaining species have genuine grumous or tuberi- 
form roots, although, as to 
D. simplex Dougl., this is only an inference; for the 
roots of Douglas’ plant, and of Spalding’s from the same 
district (W. Idaho), which accord in character, are wanting 
in the specimens. But the plant comes near to the following, 
which has commonly been taken for it. Further knowledge 
of this species is much desired. : 
D. distichum Geyer in Hook. Lond. Jour. Bot. vi. 67. 
D. azureum Torr. in Bot. Wilkes’ Exped. Common on the 
low prairies of E. Oregon and Washington Territory, and 
extending to Montana. 
D. Menziesii DC. Chiefly near the coast; Brit. Colum- 
bia to Oregon and northern part of California. There are 
puzzling specimens, but it appears to be the only grumose- 
rooted species with pretty large and slender peduncled flow- 
€rfs, succeeded by long and narrow divergently recurved 
follicles. Yet sometimes these seem to remain erect. 
D. decorum Fisch. & Meyer. This is a low and lax
