rigid, 3 ft. long or more : leaves cuneate-obovate or oblanceolate, }4. — 1 

 in. long, entire except at the truncate or retuse mostly 3-toothecl apex, 

 glabrous and rugulose above, beneath white-totnentulose between the 

 veins : fl. white : fr. in umbellate clusters, small ; horns narrow and 

 elongated, closely appressed, imbricately overlapping at the summit of 

 the capsule.— Habitat of the preceding nearly, but apparently at a some- 

 what lower altitude and not common.

23. C. cuneatus, Nutt. in T. & G. Fl. i. 267 (1838) ; Hook. Fl. i. 124 

 (1830), under Rhammis. Stems clustered, covered with a smooth gray 

 bark, 6—12 ft. high, the branchlets short and remote, glabrous or nearly 

 so : leaves cuneate-obovate or oblong, obtuse or retuse, entire, }4 i^i- iong 

 or less, exceeded by the profuse simple subsessile umbellate clusters of 

 rather large dull-white heavy-scented flowers : fr. rather large ; horns 

 short, erect. Var. ramulosus. Smaller, the branchlets more numerous 

 and more leafy : leaves narrower and longer, more tomentose beneath : 

 fl. half as large, scentless, deep blue : fr. smaller and more elongated. — 

 The type abundant at middle elevations throughout our whole district, 

 extending northward to the Columbia : the variety in the Coast Eange 

 only, and from Santa Cruz Mts., Greene, to Marin and Napa counties, 

 Mrs. Curran, Dr. Parry. Feb.— Apr. 



24. . C. crassifolius, Torr. Pac. R. Rep. iv. 75 (1857). Taller than the 

 last, the stems less clustered, more arboreous, and with darker bark : 

 young branchlets whitish-tomentose : leaves ovate or ovate-oblong, ^ — 1 

 in. long, obtuse, entire, or remotely spinose-denticulate, glabrous above, 

 white-tomentose beneath : umbels often leafy-peduncled, larger than in 

 the last, the fl. on longer pedicels : f r. rather small ; horns inconspicu- 

 ous.— A species of the southern parts of the State mainly ; but said to 

 occur in the Coast Range as far north as Mendocino Co. This, however, 

 only on the authority of the "Botany of California," whose authors 

 probably had the next in view as a part of their " C. crassifolius." 



25. C. divergrens, Parry, Proc. Davenp. Acad. v. 173 (1889). Low, 

 much branched, the branchlets stout and divaricate, hoary when young : 

 leaves 1 in. long very rigidly coriaceous, cuneate and entire below, above 

 bearing 2 or 8 pairs of opposite coarse spinescent serrate teeth, the 

 truncate apex with or without a similar tooth : umbels peduncled or 

 subsessile : fl. large, rose-purple : fr. large, elongated, with 3 prominent 

 horns and as many alternating crests.— Not common ; apparently first 

 collected in Lake Co., Dr. Torrey, later in Napa Co., Dr. Parry ; also on 

 hills near San Jeronimo in Marin Co., Dunn. Apr. May. 



26. C. rigidus, Nutt. in T. & G. Fl. i. 268 (1838) ; Hook. Bot. Mag. t.
