anthers with a pair of reflexed awns on the back. Ovary raised on a 

 hypogynous disk. Fruit a berry with granular, surface, and many seeds. 



1. A. Menziesii, Pursh. Small symmetrical large-leaved evergreen 

 tree, with hard wood, and a red-brown exfoliating bark : leaves oval or 

 oblong, deep green and shining above, entire or serrulate: fl. in an ample 

 terminal panicle of dense racemes; corolla white, nearly globular : berries 

 dark reddish. Common in the Coast Range. 



3. ARCTOSTAPHYLOS, Galen. Shrubs or small trees, with inflor- 

 escence and flowers nearly as in Arbutus. Foliage coriaceous and 

 evergreen. Cells of ovary only 1-ovuled. Fruit with hard smooth sur- 

 face, and a mealy or almost powdery pulp between it and the 5 or more 

 hard-woody or almost bony stone-like 1-seeded nutlets; these often more 

 or less firmly consolidated. 



* Ovary glabrous; branches and petioles never hispid. 



1. A. pumila, Nutt. Stems depressed, several feet long, tomentose- 

 pubescent when young: leaves obovate, or oblong-obovate, obtuse, entire, 

 short-petioled : fl. in short racemose clusters, with veiny bracts: corolla 

 pinkish: fr. orbicular, yellowish -brown; the nutlets broadly carinate, 

 occasionally partly coalescing into irregular 2-celled stones. A rare 

 undershrub, found chiefly about Monterey, but occurring at the base 

 of Lone Mountain, San Francisco. Fr. July. 



2. A. Manzanita, Parry. Trunks erect, usually clustered, the bush 

 or small tree 625 ft. high: bark mahogany-red, exfoliating: leaves 

 commonly vertical by a twist in the short petiole, rigid, ovate, with broad 

 rounded base and obtusish though often mucronate apex: peduncles 

 and pedicels of the somewhat paniculate inflorescence pubescent; 

 bractlets broad, acuminate: corolla pinkish, broadly urceolate: fr. cin- 

 namon-color, but bright and shining, depressed-globose, 46 lines 

 broad: nutlets more or less firmly coalescent, the whole including 57 

 fertile cells. Very common in the Coast Range; in Napa and Sonoma 

 counties often very large and tree-like. Fl. Nov. Feb. 



3. A. Stan for diana, Parry. Stems 35 ft. high, slender, the smooth 

 bark not exfoliating: leaves narrowly ovate to oblanceolate, tapering to a 

 short petiole, entire, mucronate, deep green on both faces: calyx red; 

 corolla pink : fruit in pendulous racemes, orbicular, much flattened, the 

 nutlets broader than high, carinate, usually 2 or more coalescent, rarely 

 all united into an irregular stone. Abundant on hills above Calistoga, 

 Napa Co. Fl. March; fr. July. 



4. A. glauca, Lindl. Erect, 8 20 ft. high, glabrous, glaucous: leaves 

 rigid, often vertical, round-ovate to oblong: racemes panicled; pedicels 

 glandular-hirsutulous; fruit large, not depressed, but rather longer than 

 broad; the nutlets completely consolidated into a 5-celled stone a half-inch 

 thick. Mt. Diablo to Los Gatos, and southward.
