Sierra Nevada, 3000 to 9000 feet, south to the San Bernardino ilts., north 

 to Modoc Co., thence west to Humboldt Co. Far north to British America, east 

 to Missouri. Strongly resembling Arenaria maerophylla.

10. S. lemmonii Wats. (Fig. 102a.) Stems slender, erect, very leafy at 

 base, 8 to 1-1 inches high, arising from the slender branched rootstoi-ks crown- 

 ing a deep-seated taproot; herbage puberulent and somewhat glandular; basal 

 leaves narrowly obovate. acute, narrowed at base, % to I14 inches long ; stem 

 leaves similar or linear or lanceolate, the upper remote and much reduced; 

 flowers nodding, in a narrow few-flowered panicle; calyx 3 to 314 lines long, 

 oblong (soon turbinate-distended by the ovoid capsule), scarious, with 10 

 green nerves, the alternate ones ending in the short rounded teeth ; corolla dull 

 or pale yellowish white, 4 to 6 lines broad; blade of petals 4-cleft into linear- 

 subulate segments, the segments entire or rarely lobed; scales entire or 2- 

 toothed. erect; auricles broad, rounded; claws woolly-pubescent; stamens long- 

 exserted, twice as long as the corolla. 



Open pine forest, 4000 to 6500 feet. Sierra Nevada. The most common 

 species in the coniferous belt. 



Biol. Note. — The flowers open in the evening, the petal blades stiffly spreading, at first 

 reflesed, later rotate; during the next morning the segments coil inwards from the tip, 

 remain closely coiled all day and do not, so far as we have observed, uncoil again. The stamens 

 are physiologically in 2 sets of 5 each: the first set becomes long-exserted, the second set 

 meanwhile remaining coiled at mouth of calyx tube; when the first 5 relax, the second 5 

 elongate ; the flowers at" protandrous and the very long styles follow the second set of sta- 

 mens or overlap them somewhat during the latter part of tlieir period of anthesis. The pro- 

 cedure in this species probably does not differ essentially in the related species.
