 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. 1. 1791 ; Hook. Bot. Mag. t. 3220. A. cordifolia, Lindl. 1. c.

 nate-cuspidate, entire, obtuse or rounded at base, slender-jietioled : 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;

 Dajihnidostnjihi/lis pungens, Klotzsch, 1. c. — Arizona and S. Utah to California. (Mex.) 



Var. platyphylla, the commoner Manz.xnita in California, especially northward, 

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

 inches long, commonly muticous. — ArctostaphyJos glauca, Watson, Bot. King, 210, &c., not

 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., under 1791 ; Gray, Bot. Calif.
