short, crowded, pubescent and very leafy : leaves coriaceous, broadly 

 obovate, truncate, retuse or obcordate, % in. long, often nearly as broad, 

 sharply but rather minutely spinose-dentate or -serrate, glabrous above, 

 more or less tomeutulose beneath : umbels many, few-flowered, sessile : 

 H. small, bright blue : fr. 34 in- thick, with short erect horns. — From 

 Monterey southward along the coast. Apr. May. 



27. C. vestitns, Greene, Pittonia, ii. 101 (1890). Stems clustered, 6 ft. 

 high, widely branching, the rigid branchlets cinereous-tomentose : leaves 

 ^'o in. long or less, hard coriaceous, subsessile, somewhat concave above, 

 round-obovate, obtuse or retuse, (on young shoots acute) sharply spinose- 

 toothed all around, cinereous-pxiberulent on both faces but more so 

 beneath : H. small, white, in numerous subsessile corymbs ; pedicels % 

 in. long, rather stout : fr. (immature) small, the short saliently spreading 

 horns inserted at about the middle. — Borders of pine forests on moun- 

 tains south of Tehachapi, Kern Co. Collected by the author in 1889. 

 C. cuitealus, occurring in the same region, and to which it is related, was 

 in mature fruit while the present species was but just passing out of 

 Hower late in June. 



28. C. metacarpus, Nutt. Sylv. ii. 46 (1848) ; C. riiaevocarpus, Nutt. 

 in T. & G. (1838), not of Cavanilles (1794), Greene, Bull. Calif. Acad. i. 80. 

 Arborescent, often 8—12 ft. high, with dark-colored rough bark and 

 rounded head of not very rigid branches ; branchlets rusty-pubescent 

 and marked by large warty stipular glands : leaves alternate, thick 

 coriaceous, obovate-cuneiform, entire, emarginate, whitish-tomentose 

 beneath : fl. in pedunculate usually simple umbels, snow-white : fr. }c, 

 in. long, with 3 horns at summit. — Summits of Santa Ynez Mountains in 

 Santa Barbara Co., NuilaJl, Greene, Parry, and to be sought in similar 

 localities on the unexplored higher mountains to the northward. A most 

 distinct species ; the only one of its group, except C. rertiicosus of the 

 San Diego mesas, with alternate leaves. Very showy, and much like a 

 wild plum-tree in aspect, when in full bloom. Feb. 



Obscure species, and liybrids. 



29. C. Veitchianus, Hook. Bot. Mag. t. 5127 (1859). Branches stalk- 

 lets and surface of leaves glabrous : stipules obvious, membranous or 

 subscarious ; blade of the leaf strongly pinnate-veined, obovate-cunei- 

 form, obtuse, the young acutely, the older obtusely glandular-serrate, 

 % in. long, smooth and shining above, tomentose between the stout veins 

 beneath : fl. bright blue, in niimerous dense corymbs at the ends of all 

 the branches. — Unknown in the living state except as cultivated in 

 England from seeds collected l)y Thomas Bridges in California. Judging 

 from the figure in the Botanical Magazine, the shrub could not be 

 referred to any species known, even as a hybrid. The leaf-outline and
