 and canescently pubescent ; segments of the leaves frequently rounded 

 or obtuse; calyx-tube 1-2^'long; petals 5 -7" long; capsules simi- 

 lar but rarely developed. — From Washington Territory to Northern 

 California and Nevada. 



30. OE. heterantha, Nutt. Perennial, acaulescent, glabrous ; 

 leaves lanceolate to oblong-lanceolate, 3-6' long, acute or acutish,

 sule 9" long, ovoid-oblong, tetragonal, attenuate above into the persist 

 ent calyx-tube, the sides nearly flat, ribbed, subreticulated ; seeds 

 numerous, -§" long, minutely pitted. — From Idaho to Northern Nevada 

 and Northern Utah. 



Var. taraxacifolia. Leaves 1° long, lyrately pinnatifid ; the 

 capsules decidedly pedicillate. — A single immature specimen has been 

 collected near Austin, Nevada ; probably distinct. 



31. GE. ovata, Nutt. Resembling the last. Root very thick; 

 subpubescent ; leaves ovate to oblong-lanceolate, shortly ciliate, 2-8' 

 long, acute, erosely or repandly denticulate or serrulate ; calyx- 

 tube 1-4' long ; petals 3 - 10" long ; filaments nearly equal ; capsule 

 y long, strongly torulose ; seeds few, in one or two rows, erect, oval,

 hairy; seeds horizontal, smooth. — California, from the Sacramento 

 River to Monterey. 



§3. MERIOLIX, Raf. (Calylophis, Spach, and Salpingia, Nutt.) 

 Stigma dilated, disciform ; calyx-tube linear to funnelform, more 

 or less broadly dilated at the mouth ; petals yellow ; anthers ob- 

 long-linear, attached at the middle, the filaments slightly unequal ; 

 capsule linear-cylindric, sessile or nearly so ; seeds in two rows in 

 each cell, ovoid or ovoid-oblong, strongly angled, very nearly
