 fours or fives, linear or oblanceolate, or lanceolate-oblong, obtuse, 4 — 7 

 lines long: peduncles slender, scattered, 1 — several-tlowered : fl. minute, 

 white, often 3-merous: fr. small, smooth, glabrous. — In wet grounds, 

 toward the seaboard in a very large form, and in the Sierra in the

7. 0. augustifoliuin, Nutt.; T. & G. Fl. ii. 22 (1841). Rigid, much 

 branched, shrubby at base, % — 4 ft. high, smooth and glabrous, or

(t. B/aoineri, Gray, Proc. Am. Acad. vi. 538 (1865). A few in. to 1 ft. high,

 broadly ovate to ovate-lanceolate, mucronate-apiculate or abruptly acumi- 

 nate, thickish, 4 — 7 lines long, with 2, or sometimes 4, lateral nerves from
