Ohd. 10. CISTACEJE. 



1. HELIANTHEMUM, Town. 



1. Helianthemum scoparium, Nutt. in Ton. & Gray. 



Hab. Sides of Mount Palmas near San Francisco, California, in 

 gravelly places. — This species is certainly annual, and not shrubby, 

 as stated by Hooker and Arnott in the Botany of Beechey's Voyage 

 (p. 135). The plant has much the appearance of Hypericum Drum- 

 mondii. 



Oed 11. HYPERICACEJ. 



1. HYPERICUM, Linn. 



1. Hypericum formosum, H. B. K. 



Hypericum formosum, H. B. K. Nov. Gen. & Spec. 5, p. 196, t. 160 ; DC. Prodr. 



1, p. 547 ; Gray, PL Wright. 2, p. 17. 

 H. Scouleri, Hook. Fl. Bor.-Am. 1, p. Ill ; Torr. & Gray, Fl. 1, p. 160. 

 H. bracteosum, Kellogg in Proceed. Calif. Acad. Nat. Sc. 1, p. 65. 



Hab. Near Nisqually, and on the Wallah- Wallah and Kooskooskee 

 Rivers, Washington Territory and Oregon, southward to California 

 and New Mexico. 



As remarked by Dr. Gray (1. c), H. formosum of Kunth differs but 

 little from H Scouleri, and he suspected they were not distinct. If, 

 as we believe, the New Mexican plant is the same as Kunth's, H. 

 Scouleri must be united with it.
