CEPHALOZIA 127 
Slender, bright- or pallid-green, prostrate, forming close de- 
pressed mats or rarely laxly creeping, rather sparingly and irregu- 
larly ramose, the apices often ascending : stem somewhat flattened 
dorsally, the cortical cells large and pellucid : leaves small, orbicu- 
` lar-rhomboidal, .18—.4 mm. in diameter, subimbricate and somewhat 
assurgent or often distant and nearly horizontal, decurrent dorsally, 
bifid about one third their length with an obtuse or rarely lunate 
sinus and connivent, acute or subacuminate lobes ; leaf-cells pellucid, 
30-45 и: dioicous : androecia occupying the end, rarely the mid- 
dle of mostly rather short branches: inmost bracts of the very 
short 9 branch about three times larger than the outer, orbicular- 
oblong, bi-quadri-fid, the segments acute or acuminate, entire ; 
bracteole nearly similar, sometimes connate with the bracts : per- 
ianth oblong- to linear-fusiform, 1.5-2.4 mm. x .4—8 mm., соп- 
stricted and denticulate at the mouth, of 2 or 3 layers of cells 
toward the base, sometimes 2-stratose as high as the middle, the 
remainder unistratose ; calyptra 2- or 3-stratose throughout : cap- 
sule cylindrical-oblong, .6-.8 mm. x .28-. 5 mm.; spores cinnamon 
colored, 
On decaying logs in moist shaded places, rarely on the ground. 
Common in the Coast Range Mountains, north of San Francisco.

The perianth in our specimens is usually of a thinner texture 
than i$ ascribed to Cephalosia multiflora by Dr. Spruce. Itis 
rarely that the perianth-wall is 2-stratose so far as the middle. In 
Most cases the perianth-wall is of more than one layer of cells only 
= the lower third or fourth, sometimes even only in the basal 
Sixth, yet we have been able to discover no other character to 
distinguish the Californian plant from the European and an exam- 
ination of European specimens seems to indicate that this character
