58 LEAFLETS. 



An exceedingly beautiful species, of sandy slopes among the 

 mountains of Washoe Co., Ifevada, collected by 0. F. Baker, 

 14 Aug. 1903, and distributed by him under n. 1461. 



A. TOMEKTELLUM. 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 ; 

 leayes 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, 1903, C. F. 

 Baker ; distributed under his n. 1309. This and all the fore- 

 going are allies of A. androscemifolium, 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 3^ 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, Oi-msby Co., Nevada, 

 C. F. Baker, 30 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 A. androscemifolium 

 group. 



A. PALUSTRE. Related to A. cannabinum, stouter, 3 to 4 feet 

 high, somewhat dichotomous ; leaves of main stem 3 or 4 inches 

 long, 3 to. 3J in breadth, oval, obtuse, only the smaller and sub- 

 elliptic rameal ones cuspidate-mucronate, all vivid green and
