5. ARCTOSTAPHYLOS Adans. Manzanita. 

 Shrubs with very crooked branches, the bark dark red or chocolate- 

 colored, smooth and polished. Leaves commonly entire, more or 

 less vertical by twisting of the petiole. Plowers white or pink, in 

 short spikes or racemes, disposed in terminal subglobose clusters or 

 panicles, usually 5-merous. Bractlets commonly scaly. Sepals dis- 

 tinct. Corolla urn-shaped. Anthers as in Arbutus; filaments thick- 

 ened above the base and hairy at the middle. Ovary raised on a 

 hypogynous disk, 4 to 10-celled, with solitary ovules in the cells, in 

 fruit forming a drupe or dry berry with several stony nutlets. 

 Nutlets either distinct, irregularly united in 2's or 3's, or sometimes 

 consolidated into a single stone. Surface of the "berry" brown or 

 deep mahogany, smooth or with resinous dots, the pulp between the 

 skin and stones mealy, or in late summer powdery. The flesh of the 

 fruit is somewhat acid and has been used in the rural districts to make 

 a cooling drink. The individuals are very abundant and in the com- 

 pany of Ceanothus cuneatus and other shrubs, form the exceedingly 

 extensive brush thickets known as chaparral which impart a marked 

 character to the scenery of the higher Coast Range ridges and moun- 

 tain summits. (Greek arktos, a bear, and staphule, a grape; bears 

 feed on the berries of some species.) 



Fruit small, 2 lines long or leps; leaves less than 1 In. (mostly '^ in.) long, 



strictly erect 1. A. nummularia. 



Fruit 3 to i% lines long; leaves exceeding 1 In. (mostly 1}4 to 2 in.) long. 

 Branchlets commonly bristly ; ovary bearded. 



Leaves cordate at base 2. A. Andersoni. 



Leaves oblong-lanceolate to ovate i. A. tomentosa. 



Branchlets glabrous or pubescent; ovary glabrous. 

 Pedicels glabrous.

diameter ol corolla 4. A. manzanita. 



Leaves vivid green, never glaucescent; calyx }^ diameter of corolla . . 



5. A. Stanfordiana. 

 Pedicels glandular-pubescent; leaves glaucous . . . .6. A. giauca. 



1. A. nummularia Gray. Strictly erect, IJ to 2J ft. high; branch- 

 lets pilose-pubescent, the foliage glabrous and shining; feaves orbic- 

 ular to elliptic-ovate, entire^ veiny on the under surface, thickly 

 clothing the branches, 5 to 11 (commonly about 6) lines long, on 

 petioles 1 line long; flowers little exceeding 1 line in length; ovary 

 bearded; fruit oblong, 2 lines long, the nutlets usua'ly 4. 



Common on the southern slopes of Mt. Tamalpais; Ben Lomond,
