 RHUS LAURINA Nutt. 



RHUS INTEGRIFOLIA Nuttall. A stout 

 evergreen shrub, at times attaining to the 

 rank of a tree, and a diameter exceeding five 

 feet. The rose colored flowers produced in 

 close panicles one to three inches long, fol- 

 lowed by deep brilliant red berries, coated 

 with an icy-looking, wax-like substance that 

 is even more tart than the pleasantly acid 

 berries. These berries make a cooling drink, 

 equal to lemonade (almost indistinguishable in 

 flavor.) 



In Southern and Lower California this is 

 often called Mahogany, from the rich and 

 beautiful color of the wood. 



RHUS OVATA S. Watson. 



"A shrub, 5-10° high, glabrous excepting

 nate, entire or rarely sparingly toothed, 

 2-3' long, on a stout, usually reddish 

 petiole 4-8" long: fl. in dense closely 

 panicled spikes %' long or less, the 

 rounded bracts and eepcls purplish; pet&Ifi 

 light y. : fr. compressed-ovate, 2-3" 

 long, viscid-pubescent."— S. Watson, Proc.

 treated as a distinct genus.

•'Prostrate, much branched, canescently to- 

 mentu lose: leaflets 5 or 7, cuncate-obovate or 

 oblong, obtuse: peduncles slender, shorter 

 tnan the leaves, the lowest bractless & 1-fl'ed, 

 the later often bracted & 2-fl'ed: corolla y, 3"

 row, compressed, an inch or more in length, 

 5-7 seeded; seeds from orbicular to oval, com-

dark red berries make a cooling drink pressed, the surface covered with a minute <t 



pleasantly flavored, resembling lemon 

 ado, and when dry are covered with 

 a thin, waxy, white substance, that is 

 very sweet, which the Indians are said 

 to have formerly gathered for sugar.
