apoda. In 1867, J. G. Agardh referred this species to the Lanii- 

 naria sessilis of his father, C. Agardh. The locality whence came 

 the type specimens of L. sessilis seems to be in great doubt, there 

 being no greater certainty than that they came from some portion 

 of the Pacific Ocean. Lyall's specimens came from the Straits of 

 Fuca. While collecting at Fort Ross, in Sonoma County, the type 

 locality for several of the kelps of our western coast, it was the 

 writer's good fortune to find an abundance of this species growing 

 upon the rocks between tides. This seems to be the southernmost 

 locality for this species unless it may perhaps extend a few miles 

 farther south to Point Reyes. It seems quite certain that it does 

 not extend south of Point Reyes to any extent, since careful search 

 at Duxbury Reef, San Francisco, Santa Cruz, and Monterey have 

 failed to reveal it. Its southward extension indicates that more 

 Vancouver forms may ultimately be found upon the Californian 

 coast and that Point Reyes probably marks the boundary of a 

 southern extension of the Vancouver algal flora. — W. A. Setchell. 



The North American Species of Chrysosplenium. — A pre- 

 liminary revision of the North American species of this genus by 

 Mr. J. N. Rose appeared in the April Gazette (xxiii, 274). 

 Chrysospleniuvi gkchomcefolkim as a name is replaced by C. Scouleri, 

 which as a varietal name antedates the name currently employed- 

 Mr. Rose gives the range of the species as "Oregon and Washington." 

 It is credited in the Flora Franciscana to Humboldt County, Calif., 

 and at a later date (May, 1895) specimens were brought to us from 

 Navarro, Mendocino Co., by Miss Edith Byxbee, a student of the 

 University of California. This is the most southerly known station. 

 C. Beringianum from St. Paul Island is described as new. The 

 other two species are C. alternifoliwn and its variety raised to spe- 

 cific rank as C tetrandrum. — W. L. J. 



The Southern Range of Lawson's Cypress. — The occurrence 

 of Ciqjressus (^CJucmcecyparls) Lawsoniana as far south as Hum- 

 boldt Bay, Cal., has been recently questioned. Mr. Henry Melde, 

 of Eureka, informs me that it is still to be seen along the gulches of 

 the Mad River, atttvining between seventy-five and one hundred 

 feet in height. — J. B. D.
