"A sm tree, 15-25 hi, trunk 6-10' in 

 diam, smooth, with a light-gray bark; 

 branches soft-pubescent: Ivs ovate, ac- 

 ute, serrate, or often rather crenate, 2-4' 

 long, g and puberulent above, w'ish and 

 soft-tomentose beneath: fls pale bl in 

 a compound raceme: fr not crested. 

 Island of Santa Cruz; common on north- 

 ward slopes in the more elevated reg- 

 ions. The largest known species, with 

 more ample foliage than is found in 

 any other; but always tree-like in shape, 

 with clean trunk and open but round 

 hd, like a well kept orchard tree; in 

 this particular most unlike any other 

 Ceanothus." Greene, Cal ac b 2:144 

 (1886). 



Sargent, Garden and Forest 2:364 and 

 Sylva NA 2:45 refers this to C. velu- 

 tinus as a variety.

Type locality: "Washoe", Nev (J. A. 

 Veatch). 



"A shrub 4 or 5 in height, branches 

 erect, flexuose; bractlets num, very 

 short, divaricate, leafy at the base, ter- 

 minating in a stout thorn; w'ish glauc- 

 ous: sts strictly terete: Ivs sm (%-%' 

 long, rarely % broad) 3-ribbed (with 

 2 other outer obscure nerves) ovate-cor- 

 date, entire, often emarginate, reticu- 

 late, with translucent veins, short hir- 

 sute above and below, especially con- 

 spicuous along the nerves beneath; peti- 

 oles short, hirsute, in the mature state 

 stout, seldom 1-16' long, in the young 

 state 2 or 3 times that length and very 

 slender, minutely pubescent; lamina be- 

 coming thickened and coriaceous, per- 

 sistent: stipules subulate, hirsute: Ivs 

 in fasciculate clusters, somewhat canes- 

 cent beneath: fls in thyrsoid panicles 1 

 or 2' in length, springing from the sum- 

 mit or approximate lateral branchlets; 

 peduncle and pedicels sub-glabrous: ex 

 pet and pedicels w at the time of blos- 

 soming, but bright pea-g before expan- 

 sion; panicles sometimes leafy at the 

 base. The form of fls as usual in this 

 genus; ex divisions inflexed turbinate; 

 pet saccate or hooded; unguiculate pistil 



2-parted about one-third its length: fr 

 unknown. This species appears to be near 

 C. hirsutus (Nutt.); but the Ivs are not 

 "nearly sessile", nor "glandularly ser- 

 rulate," nor "panicles terminal." Nor 

 does it answer to C. divaricatus (Nutt.), 

 as the Ivs are not "glandularly ser- 

 rate", and seldom half the size; nor are 

 the fls bl." Kellogg, Cal ac pr 2:124
