TWO CALIFORNIAN CRYPTOGAMS. 113 
The accompanying plate shows the outline of a frond of 
Polypodium Californicum collected in Marin County, Cali- 
fornia, January 31, 1892, by Messrs. Michener and Bioletti. 
The segments in the lower part of the frond are lobed and 
cleft instead of being simply serrate as in the typical form. 
It is undoubtedly analogous to Moore’s variety semilacerum 
of Polypodium vulgare, but observations thus far lead to 
the conclusion that the present form has too much the nature 
of an occasional sport to deserve a varietal name. Fronds 
with the lower segments more or less cleft have been noticed 
in the vicinity of Berkeley, and specimens showing a depart- 
ure from the type as great as that represented in the figure 
have recently been collected by Mr. Jepson near Olema in 
Marin County. 
But one of the interesting features of our figured plant 
and the one which perhaps chiefly justifies calling attention 
to it is its relationship to Kellogg’s P. faleatum. The size 
of the frond, which has a length of thirteen inches and a 
maximum width of six inches, the narrowly acuminate and 
faleate middle segments, and the reduced size of the two 
lowest pairs of segments, are all strongly suggestive of Poly- 
podium falcatum; but the veinlets anastomose in two or three 
eases, and this fact together with the characters of the sori 
and the shape of the upper segments induce the writer to 
believe that the nearest alliance of the plant is with Polypo- 
dium Californicum Kaultf., variety intermedium D. C. Eaton. 
The frond has a thin texture, such as may belong, according 
to the descriptions, to either of the forms in question. Plants 
showing a puzzling relationship between Polypodium falea- 
tum and P. Californicum, var. intermedium are not uncom- 
mon in the cafions about the Bay of San Francisco. 
Plate I. represents the frond reduced one-half and one 
of the segments the natural size. The middle segments are 
rather more narrowly acuminate than the figure indicates.
