usually spreading hairs : leaves ovate or sometimes oblong, acute or 

 shortly acuminate : perianth usually rather broad at base, spreading ; 

 segments acute, 5 or 6 lines long, about equalling the stamens : ovary 

 narrow, more or less pubescent ; style glabrous : fruit obovate, obtuse ; 

 cells usually 2-seeded. — Pacif. R. Rep. 4. 144. P. lanuginosa, var. 

 Hookeri, Baker, 1. c. California (Coast Ranges, Marin County to 

 Santa Cruz). 



6. P. trachyandra, Torr. 1. c. Resembling the last: leaves less 

 deeply cordate, the upper ones often not at all so, and broader toward 

 the apex : stamens a third shorter than the perianth ; anthers minutely 

 hispid : ovary glabrous : fruit glabrous, with a short stout beak. — P. 

 lanuginosa, var. trachyandra, Baker, 1. c. California (Sierra Nevada, 

 from Tuolumne to Plumas County). 



7. P. Oregana. More or less woolly-pubescent : leaves ovate to 

 oblong-lanceolate, long-acuminate : perianth-segments spreading, acute, 

 narrowed below, very distinctly net-veined, 5 to 7 lines long, equalling 

 or shorter than the stamens : fruit ovate, acutish, somewhat pubes- 

 cent ; cells 1-2-seeded. — Uvularia lanuginosa, var. major, Hook. Fl. 

 Bor.-Am. 2. 174. Oregon and Idaho to British Columbia.

* Ovules a single pair in each cell : flowers small, umbellate. 



1. C. umbellata, Torr. Inflorescence villous-pubescent or gla- 

 brous: flowers 10 to 20 or more, suberect on slender pedicels, white 

 with often a green or purplish spot at the tips ; segments broadly 

 spatulate, 3 or 4 lines long, about equalling the stamens : style slender : 

 fruit small. — Fl. N. York, 2. 301; Baker, Journ. Linn. Soc. 14.
