19. S. doiiglasii Hook. var. monantha Rob. Stems erect, several from the 

 loosely branching crown of a taproot. 10 to 20 inches high, the leaves chiefly 

 basal, the stem with mostly 1 or 2 remote pairs; herbage very minutely 

 pubescent or nearly glabrous, especially below ; leaves linear-lanceolate to 

 oblanceolate, tapering to both ends. 1 to 2Vl> inches long; stems (or the main 

 branches) 1 or more commonly 3 to 5-flowered; calyx oblong-cylindric, soon 

 inflated and ol)long-campanulate, 6 to 7 lines long, its teeth roundish, often 

 a little constricted at base, obtuse at apex or at length with the membranous 

 margins inflexed and thus acute; corolla dull white, 5 to 8 lines broad; petal 

 blades 2-cleft, its lobes entire ; claws somewhat exserted ; scales oblong, entire ; 

 auricles obtuse or acute; capsule elliptic or oblong, 4 to 5 lines long, included, 

 on a stipe llo lines long.

Specimens from Sierra, Placer and El Dorado counties in the northern Sierra Nevada are 

 very uniform in habit save in number of flowers on the flowering stems. One finds specimens 

 with the stems 3 or 5-tlowered, rarely 7-flowered. Less commonly plants are found with all 

 the stems 1-flowered, but frequently plants show all these variations on a single individual. 

 In his revision of Silene, Williams, whose material was evidently scanty, disposes of S. monantha 

 Wats., the type of which is simply the 1-flowercd state, in the subgenus Gastrosilene and places 

 S. douglasii Hook, (the many-flowered original form) in the subgenus Eusilene. In the absence 

 of ample material a specific unit may thus be broken and separated, by applying too rigidly 

 the characters of defined subgenera, which nevertheless may be sound in principle.

 from the branching crown of a taproot ; herbage finely puberulent. glandular 

 above; leaves linear to ol)lanceolate. 5 to 8 lines long, mostly 2 to 3 lines 

 broad, somewhat fleshy, densely crowded at base, the cauline pairs few and 

 reduc-ed ; flowers 1 to 4 or 5. in a loose terminal cluster: calyx purplish, broadly 

 cylindrical, soon ovoid-distended, 5 lines long, the teeth rounded; corolla pink, 

 3 to 4 lines broad ; petal blades bifid, the segments each bearing a lateral 

 tooth ; scales lanceolate ; auricles narrow, truncate ; capsule obovoid, 4 to 5 

 lines long, the stipe almost none.
