 (the upper ones often not at all so) and usually less acuminate ; stamens a third 

 shorter than the perianth ; anthers minutely hispid : ovary glabrous : fruit smooth, 

 with a short stout beak. — Pacif. R. Rep. iv. 144. P. lanuginosa, var. trachyandra,

P. Okegana, Watson, of Oregon and Washington Territory, is distinguished by its long-

 pubescent ; spreading perianth-segments (5 to 7 lines long) more distinctly (often purplish) net- 

 veined ; stamens exserted ; fruit somewhat pubescent, ovate, acutish, nearly half an inch long, 

 3 - 6-seeded. 



P. TRACHYCARPA, Watson, is a more ^eastern species of the Wahsatch and Rocky Mountains, 

 ranging north to British America. It has acute sessile not cordate leaves, stamens about e(iual- 

 ling the perianth, a slightly cleft style, rounded ovary, and obovate obtuse papillose 6-18-seeded 



-f- -1- Anthers much exceeding the very short filaments. 



4. P. parvifolia, Watson, ined. Rather stout, much branched, woolly-pubes- 

 cent : leaves ovate to broadly lanceolate, the lower cordate and clasping, 1 to 1| 

 inches long, acuminate : flowers rather numerous, 4 lines long ; segments slightly 

 spreading, twice longer than the lanceolate acute nearly sessile anthers : ovary very 

 small, slightly pubescent ; style slightly exserted.

24. CLINTONIA, Raf. 



Perianth campanulate, of 6 distinct oblanceolate deciduous several-nerved seg- 

 ments. Stamens 6, on the base of the segments ; filaments filiform ; anthers oblong 

 to linear, versatile, attached on the inner side above the base, dehiscing laterally. 

 Ovary sessile, ovate-oblong, 2 - 3-celled : cells 2 - several-ovuled ; style slender,
