H Filaments elongated, longer than the anthers.

 the margin and nerves beneath, 1| to 3 inches long, the uppermost very oblique; 

 secondary nerves often 2 or 3 : flowers 1 to 6 ; segments spreading above, 5 or 6 

 lines long, narrowed at base : stamens nearly equalling or a little exceeding the 

 perianth ; anthers 1 to 1 \ lines long : ovary narrow, more or less pubescent ; the

Var. oblongifolia, Watson. Leaves mostly oblong, acuminate. 

 In the Coast Ranges from Marin County to Santa Cruz; April to June. 



3. P. trachyandra, Torr. Very similar to the last : leaves less deeply cordate 

 (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. OUEGANA, Watson, of Oregon and Washington Territory, is distinguished by its long- 

 acuminate cordate leaves ; pedicels and upper portion of the branches usually densely woolly- 

 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. TIIACHYCARPA, 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 equal- 

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

 fruit. 



4- *- 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. CLINTOiaA, 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, 

 slightly 2 - 3-lobed at the summit, deciduous. Fruit a smooth ovoid thin few - many- 

 seeded berry. Seed with smooth brownish crustaceous testa, somewhat compressed 

 and angled. Stems very short, few-leaved, from a slender creeping rootstock, bear- 

 ing a scape-like peduncle with solitary or umbelled flowers ; leaves apparently radi- 

 cal, alternate, large, oblanceolate, sheathing, many-nerved with transverse veinlets, 

 ciliate. 



A genus of half a dozen species, divided equally between the Atlantic States, the Pacific coast, 

 and Eastern Asia. 



1. C. uniflora, Kunth. More or less villous-pubescent throughout : stem very 

 short (an inch or two long), mostly subterranean : leaves 2 to 5, acute, attenuate
