rusty-colored pubescence; leaves alternate, rather crowded, sometimes a 

 little fascicled in the axils, thick and coriaceous, obovate-cuneate, entire, 

 often emarginate, glabrous above, whitish and minutely tomentose- 

 canesceut beneath, [1-ribbed, pinuately veined]; flowers in lateral pedunc- 

 ulate nearly simple umbels; fruit very large, with three projecting horn- 

 like appendages at the summit." Mountains of St. Barbara, California, 

 Nuttall! — A shrub 3-6 feet high. Fruit twice or thrice as large as in the 

 preceding.— Torrey & Gray, Fl. N. Am., i, 267 (1S38). 



With this I would include the "C crassifolius^'' of the 

 lists from Santa Catalina and Santa Cruz islands, which 

 is indifferently either alternate- or opposite-leaved. C . 

 macrocarpiis is said in Flora Franciscana to belong to 

 the "Summits of Santa Ynez Mountains." I found it 

 to be most common at low elevations. The fruit, as will 

 be seen, is very variable in size. The shrub at Santa 

 Barbara appears to be constantly alternate-leaved, but 

 just beyond the summit of the pass occurs C. ciincatus 

 (No. 95) with opposite leaves and scarcely otherwise to 

 be distinguished. The character is evidently of no spe- 

 cific value in view of the behavior of the island form. 

 Alternate leaves are occasionally found in other localities, 

 on vigorous shoots of otherwise normal plants. No. 89, 

 Santa Barbara; No. 88, Santa Catalina Island. 



20. Ceanothus verrucosus Nutt. 



16. Ceanothus verrucosus (Nutt. ! mss.) : " Branches verrucose, and (as also 

 the veins of the lower surface of the leaves) somewhat canescent, with a 

 rusty-colored pubescence; leaves alternate, approximate or crowded, very 

 thick and coriaceous, roundish-obovate or cuneate-oval, often emarginate, 

 [1-ribbed, pinnately veined], the younger ones sometimes obscurely ser- 

 rulate, glabrous above, minutely tomeutose-canescent beneath; umbels 

 axillary, few-flowered, naked; fruit with minute protuberances at the 

 angles. Low hills near the coast, St. Diego, California. — Leaves about 

 half an inch long and 4-5 lines wide, similar to the preceding in texture, 

 venation, kc. Flowers white. Fruit the size of a large pea." — Verj- near 

 C. cuneatus fi, and perhaps only another variety of that species; from 

 which it differs, however, in its broader leaves and tuberculate stems, as 

 well as in the minute tubercles of the fruit. — Torrey & Gray, Fl. N. Am., 

 i, 267 (1S3S).
