25. OROGEMA Watson, King's Rep. v. 120, t. 15.- 

 Dwarf, glabrous, nearly acaulcsceiit plants, from tuberous or fusi- 

 form roots (underground part of the stem sheathed with large 

 scarious bracts), with ternatc leaves and linear segments, no invol- 

 ucre, involucels of few linear bractlets, and white flowers in sub- 

 compound umbels with very unequal ra\ s. 



This very peculiar and distinct genus is like Erigenia in habit and 

 time of blooming, as is said in the original description, but it is far removed 

 from It in fruit structure. 



1. O. linearifolia Watson, 1. c. Stem (or scape) slender, 

 rising 1 to 2 inches above ground from a deep-seated round tuber: 

 leaves 2 or 8, once or twice ternate, upon slender petioles; leaflets 

 entire, 1 to 2 inches long, 1 to 8 lines wide, obtuse: umbels 2 to 

 4-rayed, with nearly sessile flowers: fruit 1 1^^ to 2 lines long, 

 lateral ribs and commissural projection much m(^re strongly devel- 

 oped than in the next. (Fig. 97. ) 



Utah, in the Wahsatch (Watxoti, JoneH); Idaho (Wilcux); Oregon 

 (CuHick); and Washnigton Territory (SukfxJorf). Fl. in eaily spring. 



2. O. fusiformis Watson, Proc. Am. Acad. xxii. 474. 

 Stouter, 8 to 6 inches above ground, from a long fusiform root: 

 leaves more compounded, 2 or 8-ternate, with terminal leaflets 

 often 8-parted; leaflets an inch or less long: umbels (J to lO-rayed; 

 rays longer: fruit about 8 lines long, 1 j^ lines broad, lateral ribs 

 and commissural projection smaller. (Fig. {)H.)
