Phycotheca Boreali-Americana. Collins, Holden, and Setchell. 648. Pikea pinnata setcheii mss. Growing on stones at and just below extreme low water mark at Fort Point, San Francisco, California, Feb. 18, 1898. W. A. SETCHELL. Fronds reaching a height of 25cm., broadly pyramidal in outline ; main stem sometimes prominent but obscured in all larger plants by the long and flexuous primary branches, decidedly flattened and usually nar- row ; primary branches arising irregularly; secondary branches and branchlets more uniform and arranged in a very regularly pinnate fashion ; cystocarps situated in the short and much swollen tips of the branchlets, considered by Schmitz to be characteristic of the genus Pikea; structure of the frond as in P. California Ilarv. The specimens referred to this species have been among the assem- blage of forms passing under the name of P. Californica. The habit of the plant is totally different and constantly so. W. A. S. 6 7 8 9 10 w, -v T V The New York Copyright reserved Botanical Garden ^bbariuaTSv COLUMBIA 00900591
