58 LEAFLETS. 
An exceedingly beautiful species, of sandy slopes among the 
mountains of Washoe Co., Nevada, collected by C. F. Baker, 
14 Aug. 1902, and distributed by him under n. 1461. 
A. TOMENTELLUM. Size of the last, equally stout, branched 
from the base, with looser ampler inflorescence, the peduncled 
cymes arising both terminally and from all the upper leaf-axils. 
leaves all smaller, subcordate-ovate, obtuse, mucronulate, both 
faces, as well as the whole plant, even to the calyx cinerously 
tomentulose: sepals ovate, acute, short: corolla flesh-color, 
middle-sized, with cylindric tube and deep ovate-oblong obtuse 
segments: follicles not seen. 
King’s Canon, near Carson City, Nevada, 1 July, 1902, C. F. 
Baker; distributed under his n. 1209. This and all the fore- 
going are allies of 4. androsemifolium, while all the following 
are allies of A. cannabinum, with the possible exception of 
A. oliganthum. 
A. OLIGANTHUM. Two feet high or less, with the pale hue of 
A. cannabinum, but foliage less upright and somewhat spreading, 
the branching not dichotomous, rather fastigiate, each branch 
ending in a small few-flowered cyme shorter than its subtending 
pair of leaves, the cyme terminating the main stem little sur- 
passed by those terminating the subequal branches: herbage 
glabrous, the oblong cauline leaves 24 inches long, subcordate, 
short-petiolate, of a vivid green above, the slender whitish 
veins conspicuous, underneath pale and glaucous, those of the 
branches half as large, exceeding the internodes, all mucronate- 
acute: sepals ovate-trigonous, not half the length of the tube 
of the small cylindric erect white or pinkish corolla. 
Borders of thickets in King’s Canon, Ormsby Co., Nevada, 
C. F. Baker, 20 Aug. 1903. Distributed under n. 1508, and 
described by Mr. Baker as being a rather low broad bushy plant 
which would indicate kinship with the 4. androsemifolium 
group. 
A. PALUSTRE. Related to A. cannabinum, stouter, 3 to 4 feet 
high, somewhat dichotomous ; leaves of main stem 3 or 4 inches 
long, 2 to 24 in breadth, oval, obtuse, only the smaller and sub- 
elliptic rameal ones cuspidate-mucronate, all vivid green and
