 Character transferred and enlarged. Four to eight feet in height with 

 slender branches light graj' or reddish, younger shoots densely rusty- 

 pubescent; leaves somewhat rigid, crowded on short stems, short petiolate, 

 narrowly ovate (15 X 6 mm.), dull green above, hoary pubescent beneath, 

 triple-nerved from the base, with inconspicuous mid-veins, more or less 

 strongly revolute, margins entire, but glandularly ciliate; inflorescence 

 short pedimculate, not exceeding the leaves — flowers not seen — fruit 4 mm. 

 broad, smooth, with resinous exocarp, cocci with blunt apical crests. 

 Habitat: — Known only from fruiting specimens collected on the summit 

 of Mount Tamalpais, Marin County, July, 1886, by Mrs. M. K. Curran; 

 closely allied to C. cordulatux, but differing in the character of its foliage, 

 and peculiar in its isolated locality. — Parry in Proc. Davenp. Acad., v. 168

'^Ceanothus azareiis, Kellogg. This species is supposed to be new. The 

 provisional name indicates the exquisite beauty of its flowers, which 

 are the most vivid azure or cobalt-lilac color. Stem dull red, minutely 

 warty, with occasional pubescence: branches terete. The young branches 

 and racemes short canescent pubescent. Leaves ovate sub-acute; lesser 

 leaves obtuse, somewhat fasciculate, glandulously serrate, strongly 4-nerved 

 from the base; densely white velvetj^ beneath and along the veins, glabrous 

 and shining as if varnished above. Flowers on axillary, elongated, com- 

 pound racemose-peduncles leafy at the base, about three inches in length;
