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, ami those of the recently described 

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

 and Texas." 



CARYOPHYLLE.E. 



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. (3G2.) 



Silenk Menziesit, Hook. — Twin Lakes, Colorado. (355.) 



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

 Rolir.)— 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, l£-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 & 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 G' long, upper ones shorter; racemes sub- 

 compound, i. c, 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.)
