 long: leaves half inch or at most an inch long. 



A. pumila, Nutt. A foot or less high, tomentulose : leaves pale, oblong-obovate, obtuse 

 or retuse, sometimes obscurely mncronulate, entire, short-petioled : fruit unknown. 

 Trans. Am. Phil. Soc. n. ser. vii. 200 ; Gray, But. Calif. I.e. DaphnidoslaphyHs pumila, 

 Klotzsch, I.e. Monterey, California, Nutt all, Rich. Not yet met with by recent col- 

 lectors. 



A. Hookeri, Don. A foot or two high, diffuse, puberulent or glabrate : leaves green, 

 ovate or oval, cuspidately mucronate or acuminate, sometimes spinulose-denticulate, slen- 

 der-petioled : fruit glabrous, 2 lines in diameter, reddish. Syst. iii. 836. Arbutus punrjens, 

 Hook. & Am. Bot. Beech, 144. Andromeda ? venulosa, DC. Prodr. vii. 007. Xerobotrt/s 

 venulosus & Arctostaphylos acutu? Nutt. in Trans. Amer. Phil. Soc. 1. c. A. punrjens, partly, 

 Gray, Bot. Calif, i. 453, into which it may pass. But the smaller forms seem quite distinct, 

 and the drupes are very small. Monterey, &c., California. 



A. nuilimularia, Gray. A foot or two high, nearly glabrous, excepting scattered setose 

 bristles on the branches and short petioles, very leafy : leaves mostly broadly oval with 

 both ends rounded or the base slightly cordate, usually entire, bright green : fruit unknown.

* # * Erect shrubs or low trees, with short clustered racemes: flowers 3 or 4 lines long and drupes 

 4 or 5 lines in diameter, yellowish turning reddish : leaves 1 to 3 inches long. 



A. Anderson!!, Gray. Long and spreading bristles copious on the branchlets,&c. (along 



with fine pubescence) : leaves thin, bright green, glabrous, lanceolate-oblong to ovate-lan- 

 ceolate, with a sagittate or cordate base, sessile or very short-petioled, conspicuously 

 spinulose-serrulate or rarely entire : drupes depressed, densely clothed with exceedingly 

 viscid-tipped bristles. Proc. Am. Acad. xi. 83, & Bot. Calif. 1. c. Santa Cruz, California, 

 under Redwoods, Anderson. 



A. tomentosa, Dougl. Tomentose or pubescent when young, and the branchlets, &c., 

 usually bristly : leaves pale, coriaceous, oblong-lanceolate to ovate, entire or sparingly 

 spinulose-serrulate, petioled ; the base acutish, rounded or subcordate : ovary hirsute : drupes 

 minutely puberulent or becoming glabrous. (Runs into endless forms, of which one has 

 narrow-oblong and rather small leaves, acutish at base, apparently connecting with the 

 next species.) Lindl. Bot. Reg. t. 1791. A. cord/folia, Lindl. I.e. Arbutus tomentosa, Pursh.

 viii. 268. Drv hills, from Puget Sound to San Diego Co., California, and Arizona. The 

 berries are used in California in iufusiou for a subacid driuk. Nutlets 8 to 10, either all 

 separate or some united in pairs. 



A. pungens, HBK. Glabrous or minutely tomentose-pubescent, 3 to20 feet high : leaves 

 thick and rigid, green or glaucescent, oblong-lanceolate to round-ovate, commonly mucro- 

 nate-cuspidate, entire, obtuse or rounded at base, slender-petioled : pedicels glabrous : 

 drupes smooth and glabrous : nutlets thick-walled, carinate or thickened on the back, 

 sometimes firmly coalescent. Nov. Gen. & Spec. iii. 278, t. 259; Hook. Bot. Mag. t. 2937 ; 

 Lindl. Bot. Reg. xxx. t. 17 ; Torr. in Emory Rep. t. 7 ; Gray, Bot. Calif, i. 453, in part. 

 Daphnidostapkylis /ninr/ens, Klotzseh, 1. c. Arizona and S. Utah to California. (Mex.) 



Var. platypliylla, the commoner MAXZANITA in California, especially northward, 

 reaching Oregon, Nevada, and Utah : leaves pale or glaucescent, oblong to orbicular, 1 to 2 

 inches long, commonly muticous. Arctostaphylos tjlauca, Watson, Bot. King, 210, &c., not 

 Lindl. A. punrjens, Gray, 1. c., partly. 



3. XYLOCOCCUS. Leaves coriaceous and evergreen, entire : drupe not warty, 

 ovoid-globose, witli a thin pulp and a thick completely solid woody or bony 1-6- 

 celled putamen. -- Xylococcus, Nutt. 1. c. vii. 258. 



A. glauca, Lindl. Erect, 8 to 24 feet high, wholly glabrous except the glandular-pubes- 

 cent slender pedicels : leaves, &e., as of A. punrjens, var. ]i/<iti//>hi/lla, or paler : drupes half an 

 inch or more in diameter, minutely glandular, sometimes viscid, with a thin flesh around 

 the solid mucronate-apiculate stone : seeds and cells 4 to 0, or by abortion fewer, very 

 small in proportion to the size of the putamen. Bot. Reg., tinder 1791 ; Gray, Bot. Calif. 

 i. 454 California, commoner from Monterey southward. Except by the larger and solid 

 drupe hardly distinguishable from the common glaucous variety of A. pungens.
