CEPHALOZIA 129 
Contra Costa Co.; Fruit Vale, Alameda Co. (Miss Edith S. Byx- 
bee). Also gathered by Dr. Bolander. 
In the Californian specimens, underleaves can nearly always be 
detected toward the apex of the younger stems or branches. 
40. Cephalozia divaricata scabra var. nov. 
Leaves mostly opaque, often of two or three layers of cells 
at base, especially near the median line, the back near the fold 
usually papillate, verrucose, spinulose-dentate, subciliate, almost 
lamelligerous, or subradicelliferous, the margins now and then 
subdenticulate or at the base even spinulose-dentate, the lobes 
sometimes apiculate, cuticle of the leaf-cells distinctly roughened : 
stems exhibiting rarely here and there minute paraphyllia-like ap- 
pendages, usually composed of 2 or 3 cells in a lineal series: 
perianth-wall often bistratose in the basal fourth or fifth. 
On rocks. Near Hay Fork (1110), Trinity Co.; Doolan's 
Cafion (776), near Ukiah, Mendocino Co.; Cazadero, Sonoma 
се. 
This variety, especially as represented іп the first two specimens 
cited, is so strikingly different from the normal form that we were 
at one time on the point of treating it as a species, which we were 
finally deterred from doing by discovering that two or three of 
our Californian specimens, ¢. g., those cited under C. divaricata 
from Mt. Diablo and (in part) from Lake Lagunitas, seem to hold 
a clearly median ground, the leaf peculiarities of the two forms 
being in one observed case even exhibited in different parts of a 
single plant. We have sometimes seen a very distinctly roughened 
ог Subpapillate cuticle in European specimens of C. divaricata, 
*. £., Carr. & Pears. Hep. Brit. 261, but spinulose teeth or even 
short cilia 2 or 3 cells long from the back of the leaf we have 
been unable to discover elsewhere and we find no record hitherto 
of any such peculiarity in this species or its allies.
