c. Glandulosi. Branches terete, slender, more or less 

 resinous-warty . Leaves i- or ^-nerved of rather 

 thin texture, conspicuously glandular . Fruit small, 

 moderately crested. Flozvers mostly deep blue 

 (usually pale in C . hirsutns) but occasionally white 

 in all of them. 



16. Ceanothus oliganthus Nutt. C. Orcuttii* 



Ceanothus olir/anthus (Nutt. mss.): "Stem and branches villous; leaves 

 elliptical -ovate, nearly glabrous above, villous beneath, glandularly ser- 

 rulate, rather obtuse [3-ribbed from the base]; panicles lateral and term- 

 inal, very short, few-flowered, naked or leaf y towards the base, persistent; 

 disk pentangular; ovary with 3 protuberances at the angles nearly as 

 large as itself. Bushy woods on the hills of St. Barbara, California. — A 

 shrub. Leaves on moderately long jsetioles. Clusters of flowers scarcely 

 longer than the leaves. Flowers white, rather large." Nuttall. — Torr. & 

 Gray, Fl. N. Am., i, 266 (1838). 



This species has long been inchided in C. hirsutus, al- 

 though in the localities where they grow together they 

 are easily distinguishable. They are however connected 

 by such a series of intermediates that it seems best to 

 consider C. hirsutus merely a variety. The name oligafi- 

 M//5 has precedence. No. 30, Santa Barbara; No. 31, 

 Pasadena; No. 32 (C Orcuttii), mountains back of 

 San Diego at elevations of 800-1500 feet. The hairy 

 ovaiy and fruit on which C . Orcuttii was founded, are 

 found in less degree in the type form of C . oliganthus. 



* Ceanothus Orcuttii, n. sp. Branches flexible, dull reddish, with short 

 hispid pubescence; leaves petiolate, broadly orbicular to oblong-cordate, 

 usi;ally rounded obtuse, 30 to 40 mm. in length, often as broad, irregularly 

 glandulai'-serrate, sparingly hispid above, strongly triple-nerved beneath, 

 with prominent hairy ciliate veins; inflorescence axillary, oval scarcely 

 exceeding the leaves, i-afher compact, with pubescent rachis and smooth 

 pedicles; flowers ajoparently white or light bhie (seen only in fallen frag- 

 ments); fruit glandular-hispid, with corrugated resinous epicarp and con- 

 spicuous crests; seeds light brown. — Habitat: — High mountains east of 

 San Diego. C. K. Orcutt, May and July, 1889. Remarkable for its gland- 

 ular-hispid fruit, nearest allied to C. sanguineus Pursh. —Parry in Proc. 

 Davenp. Acad., v. 194 (1889).
