ifolius. No. 82, near Cahto, Mendocino County. What 

 appears to be this variety was collected on Guadalupe 

 Island by Dr. Palmer and by Dr. Franceschi. 



Var. Greggii (Gray). 



Ceanothus Greggii (sp. uov.): divaricato-ramosissimns; ramiilis tomeu- 

 teuso-puberiilis; foliis coufertis ellii^ticis obloiigisve integerrimis coriaceib 

 crassis nuinerviis glabellis snbtus leviter penuinerviis priinum tomeutu- 

 losis (3-5 liu. longis); pedicellis piibescentibus (demnm glabratis) flore 

 albo panllo longioribus. — (Battlefield of Biieua Vista, Gregg; iu flower.) 

 Side of mouutains uear Frontera, New Mexico, July; iu fruit. — Shrub 2-5 

 feet high, with vei'y rigid branches. Pedicels shorter thau the leaves. 

 Flowers small. Fruit about 2 lines'iu diameter. — I have only poor speci- 

 mens of this species. It bears a considerable resemblance to small-leaved 

 forms of C. cuneatus, Nutt.; but the leaves are not narrowed towards 

 the base, and the pinnate veins underneath are obscure. — Gray in Planta? 

 Wrightiaufp, ii, 28 (1853). 



C. Greggii, of which I have not seen the type, is al- 

 most equally connected with C . rigidus and C . cuneatus. 

 To it is perhaps best referred C . vestitus* (part of No. 

 99, from Tehachapi), though it is apparently quite as near 

 some of the forms referred to the next variety. Speci- 

 mens of C. rigidus collected at San Simeon (No. 92) 

 are intermediate between C. Greggii and C. rigidus, and 

 connect closely with the next variety. 



Var. CRAssiFOLius (Torr.) 



Ceanothus crassifolius, [Torr. in Emory's Mex. Bound Rep., cum tab. 

 hied.:) fruticosus, ramulis pubescentibus; foliis ovatis, integerrimis, vel 

 remote spinuloso-denticulatis coriaceis crassis penuinerviis, supra demum 

 glabratis, subtus albo-tomeutosis, thyrsis subsessilibus umbelliformibus 



* Ceanothus vestitus. Near C. cuneatus, and like it iu size and habit: 

 leaves and brauchlets ashy-tomeutulose, the former opposite, coriaceous, 

 sobsessile, 4 to 6 lines long, round-obovate, obtuse or retuse, somewhat 

 concave above, sharply spinulose-dentate all around: flowers white: cap- 

 sule apparently small, the short salient apj^eudages inserted at about the 

 middle. — Borders of pine forests on the mountains uear Tehachapi, Kern 

 Co. Calif. 25 June, 1889; growing with G. cuneatus, the latter at that time 

 with almost mature fruit; C. ves<?<?<s being only well past flowering. — E. L. 

 Greene in Pitt, ii, 101, June, 1890).
