Mountains of North Carolina. 



1 1 Western species: plants 3 inches to 2 feet high : capsules o-lobed, 3 or 

 4 lines long: petals bright yellow, often tinged with purple, with a few black 

 dots along the margin. 



22. H. foniiosuni HBK. var, Scoiileri. From running root- 

 stocks, simj)le or somewhat brandling, often with numerous 

 small branchlets, a half to two feet high : leaves ovate-oblong, 

 obtuse, more or less clasping, about an inch long, half inch or 

 more wide (those of the branchlets much smaller and often ta})er- 

 ing at base), usually black dotted along the margin of the under 

 surface, veiny : flowers half to an inch in diameter, in loose 

 corymbs : sepals lanceolate to ovate, obtuse or acute : styles 

 mostly erect.

Throughout all our western mountain systems, and extending into British 

 Columbia. 



Exceedingly variable. The species is Mexican, and differs from our va- 

 riety only in its narrower and acuminate sepals. It is really questionable 

 whether our forms deserve to rank even as a variety, as there are found among 

 them sepals which ai-e almost indistinguishable from those of H. formosum. 



23. H. coueiiiuuin Bexth. Somewhat shrubby and branching 

 at base, 3 to 18 inches high : leaves linear to oblong, not clasp- 

 ing, usually folded, half to over an inch long, 1 to 4 lines wide, 

 acute : flowers over an inch in diameter, few, in rather close clus- 

 ters at the summit of the stem, with black lines as well as dots: 

 sepals ovate, mucronate-acute, or very acuminate, longer than the 

 capsule.— PI. Hartw. 300; Brewer & Watson, Bot. Calif, i. 81.

California. First collected by Hartwccj, in the " Sacramento Valley." 



J3. Stamens 5 to 20, mostly in 3 clusters: styles 3 (sometimes 2), short, 

 distinct; stigmas capitate : capsules ovate to conical, one-celled ; seeds yellow, 

 more or less striate and pitted : small and slender annuals, with very small 

 flowers, and petals shorter than the sepals. 



"•■•Procumbent or ascending, or forming dense mats, diffusely branching : 

 leaves rather broad, obtuse, clasping: capsule a line or two long.
