PHACELIA HUMILIS T.&G. This species is described as being 
diffusely branched from the base and with the leaves all alternate. 
Specimens from Lassen Co., Baker GS’ Nutting, are diffusely 
branched but have the lower leaves opposite. Specimens from 
Marlette Peak, Washoe Co., Nevada, Hall & Chandler, No. 
4577, vary from the type form in being strict, nearly simple- 
stemmed, and in their opposite lower leaves. This form comes 
also from Lassen Creek, Modoc Co., California, M/s. Austin. 
But in all its forms P. humilis may be distinguished from P. race- 
mosa and P. Pringlet, the only other species with opposite leaves, 
by the hirsute pubescence, larger flowers, and exserted stamens. 
ErRIODICTYON LospBii (Gray) Greene, Bull. Calif. Acad. i. 202 
(1885). This species ranges farther north and east than has 
been generally supposed, and is to be expected in the arid Transi- 
tion Zone almost anywhere in the northern Sierra Nevada. It 
has been collected at the south base of Mt. Shasta, at Sardine 
Lake, Sierra Co., in the lava beds of Modoc Co., and in Nevada 
(Washoe Co.). ‘The leaves are of two sorts, the lower and the 
fascicled ones being duJl green and glandular above, loosely 
tomentose beneath, strongly revolute, at times so much so as to 
seem almost cylindric, while the upper ones are white-tomentose 
on both sides, plane, and 4 to 12 mm. broad.

' Mts., Los Angeles Co., June, 1897, /. H. Barber, No. 216, in the 
- Same district as Acton, where it has been collected by Dr. Hasse.* 
Herbaceous throughout, 5 dm. high: leaves 3.5 to 4.5 cm. long 
by 3 to 4 cm. broad, on petioles 1 to 1.5 cm. long: longest pedi- 
cels 4 cm. long: calyx-tube 13 mm,, the teeth 4 mm. long. 
MARTYNIA PROBOSCIDEA Glox. Occurs as a waif at Keene 
Station, Kern Co., Sept., 1904, 7. D. Woolsey, also found at Palo 
Verde, Riverside Co., on lowlands near the Colorado River, 1905, 
Lou Wiley, but in fruit only, and determination, therefore, not 
certain. 
ERIGERON COMPOSITUS Pursh. Summit of Mt. San eons, 
June 26, 1904, Mrs. C. M. Wilder. The plants are low and com 
pact, as in the var. discoideus, with which they grow; the rays 
evident but short and apparently pale.
