 of Virginia City " is not far from the State line. 



5. C. uiiibellatum, Greene, 1. c; Torr. PI. Frem. 4. t. 1 (1850) under

 ascending or erect, about 1 ft. high : leaves mostly radical, in a rosulate 

 tuft, spatulate or oblanceolate, 1 — 4 in. long inchiding the petiole ; the 

 cauline reduced to bracts ; an involucre of siiiall scarious bracts sub- 

 tending the terminal whorl of dense nearly sessile spikes : sepals 

 scarious and pinkish or flesh-color, 2 — 4 lines broad, about equalling the 

 obloug-obovate petals : capsule round-ovate, compressed, surmounted 

 by a long style, few-seeded : seed obliquely oval. — In the Sierra Nevada
