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. Califomica Harv.
The specimens referred to this species have been , nong the assem-
blage of forms passing under the name of P. Californicai. ' The habit of
the plant is totally different and constantly so.
