70 BOTANY. 



Nevada, of which form Mr. Watson remarks, "Nearly glabrous, with some 

 stiff hairs upon the stipules and traces of pubescence upon the stem and 

 capsules. The leaves are intermediate between the ordinary form of Cali- 

 fornia, with mostly obovate leaves, and those of the recently described 

 species (F. Jamesii, Torr.; Gray in Proc. Amer. Acad. 8, 622). Colorado 

 and Texas." 



CARYOPHYLLE^. 



Saponaria Vaccaria, Host. — Introduced about the Mormon settlements 

 in Utah. 



Silene acaulis, L. — Utah, Colorado, among the mountains at 11,500 

 feet altitude and upward. (362.) 



Silene Menziesii, Hook. — Twin Lakes, Colorado. (355.) 



Silene Greggii, Gray (PI. Wright. 2, p. 17). (Melandrium Grcggii, 

 Rohr.) — More or less viscidly pubescent; two or three erect stems from the 

 same perennial root ; lower leaves lance-ovate or obovate, shorter than the 

 upper, which are lanceolate to ovate, sessile or tapering into very short 

 petioles, 1 £-2' long ; calyx-lobes obtuse, or acute, sometimes with scarious 

 margins; lamina of petals crimson, divided into 4 lobes, of which the lateral 

 are the shorter, corona 2-parted, truncate, with the lobes slightly erose- 

 dentate. Stamens exserted. Mount Graham, 7,000 to 9,500 feet altitude. 

 (420, 734.) Also collected by Dr. Loew on the mountains of Arizona. This 

 species Mr. Watson considers a variety of S. laciniata, probably correctly. 



Silene Scouleri, Hook.— Stem erect, smooth below and . slightly 

 glandular-pubescent above ; leaves narrowly lanceolate, tapering very 

 gradually to the base, lowest 6' long, upper ones shorter; racemes sub- 

 compound, i. e., two or three flowers coming off at the same point of the 

 stem. Calyx about as long as the pedicel, lobes acute, with scarious, ciliate 

 margins ; petals white or flesh-colored, claws with acute auricles, filaments 

 woolly, ciliate ; capsule three times longer than the stipe. Mount Graham, 

 Arizona, at 9,000 feet altitude. (739.) 



Lychnis apetala, L. — Colorado. 



Lychnis Drummondii, Watson. — South Park, Colorado. (363.) 



Cerastium vulgatum, L. — Colorado. (352.)
