1. A. Menziesii, I'ursh. A handsome tree, or southwards a shrub, with very 

 hard wood, and close and smooth bark turning brownish red (the older exfoliating) : 

 leaves oval or oblong, either entire or serrulate, pale beneath, bright green above : 

 i-acemes dense, minutely tomentose : corolla almost globular, white : berries dry, 

 orange-colored (hardly eiitable), with surface granulate. — Nutt. 8ylv. iii. 42, t. U5.

 XXV. t. 07, a smaller leaveil Mexican form. 



Along the coast ranges and sparingly on tlie loot-liills, extending north to I'uget Sound, and 

 southea'stward into Mexico and Texas. In the northern coast ranges this is sometimes a mag- 

 nilicent tree, HU or lt)() Icct iiigh, witli trunk IVoni one to tliree feet in diameter. Indeed, a tree 

 in Miirin Co., iiortii til' 'raiiial|)ais, measured '2;J feet in eireumlVrencui at tho smallest part of the 

 trunk below the branehes, and some of the nmin brunches were 2 or 3 i'eet in diameter. South of 

 San Francisco Bay it is usually a small spreading tree or a large shrub. 



3. ARCTOSTAPHYLOS, Adanson. ]\lANZANrrA. 



Flowers liko those of Arbutus (but occasionally 4-merous and 8-androus), except 

 that tho D to 10 cells of tho ovary ci)ntaiu each a single suspended ovule, and tho 

 berry-like fruit a circle of 5 to 10 separate or separable bony seed-like stones, or else 

 these cohere more or less, sometimes completely into a solid several-celled or by abor- 

 tion occasionally 1-celled stone. — Shrubs or small trees; witli the alternate leaves cori- 

 aceous and persistent (in all but an arctic-alpine species), either entire or with a few 

 irregular teeth ; the white or roso-colored flowers iu terminal often clustered racemes.

The freater i>art of the S]>ecies aie Califonuan (including the Uva-ursi, which extends round 

 the woHd) : tiieir discrimination is diliicult. As to the genera proposed by Zuccarini, Nuttall, 

 and Klotzsch, mainly ujion the concretion of the .stones ol' the Iruit, this sometiuuss takes jdaie 

 even in A. Uva-ursi, and is variable in our other species. A. puiuj ens and A. gUnau, otherwise 

 hardly distinguishable, diller greatly in this respect. 



§1. Drupe not ivarty ; the flesh at maturity mealy ; the stones commonly stj>urute or 

 separable, at least some of them, not rarely some of them nnited or -1-celled 

 and 1- seeded : bracts Jirm and persistent. 

 * Ovary and depressed-globose fruit more or less pubescent : branchlets often hispid. 



1. A. Andersonii, Gray. Erect, G or 10 feet high : branchlets minutely tomen- 

 tose when young, hispid with long and white bristly hairs : leaves thin-coriaceous, 

 green and glabrous, except the bristles on the midrib beneath, lanceolate-oblong or 

 ovate-lanceolate with a strongly sagittate-cordate base, sessile or nearly so, mucro- 

 nato-pointed, mostly .spiuulose-scrntlate (2 or .'5 inches long) : fruiting pediceLs id)out 

 etpialling tho bracts: drupes rtHhlish, much dei)ressed, 4 or 5 lines in diameter, 

 densely clothed with exceediiigly viscid bristles. — Proc. Am. Acad. xi. 811. 



In the mountains behind Santa Cruz, among redwoods (Big-trco Grove), Dr. Anderson. Fila- 

 ments somewhat hirsute. Bark jialer than in the Manzanilas. 



2. A. tomentosa, Dougl. Erect, 2 to 6 feet higli, tomentose when young, 

 hispid with long spreading hairs on the branchlets, petioles, &c., but these some- 

 times nearly wanting : leaves thick and very rigid-coriaceous, varying from oblong- 

 lanceolate to ovate and even cordate, entire, rarely serrulate, often cuspidate-mucro- 

 nate, usually becoming vertical (one or two inches long) : flowers in very short
