has black spores which are papillose, while Anthoceros Pearsoni M. A. 
Howe has yellow spores with crescentic markings. This latter species 
is by far the most common. It is not rare at Catalina Island, and at- 
Santa Barbara I saw a bank thickly covered with it and extending for 
several hundred yards. 
Among the more conspicuous hepatics are the Asterellas. These 
plants may be found as early as November, but the fruit does not fully 
mature until March. Asterella California ( Hampe) Underw. is the com- 
monest species. This plant is dioicous and both male and female 
plants may usually be found growing near together. The receptacles 
in this species are 4-lobed. Asterella Palmeri (Aust. ) Underw. grows 
in more sunny places. This species is monoicous and the recep- 
tacle is not lobed, but conical. 
The genus Cephaloziella is represented here by two species. Cephalo- 
ziella Starkii (Nees) Schiffn. is nearly, if not quite, identical with C. 
divaricata (Sm.) Schiffn. while Cephaloziella divaricata scabra (M. A. 
Howe) may be recognized by its serrulate leaves which have several 
large papillae on their under sides. Both of these interesting species 
seem to be fairly well distributed, but on account of their minute size 
it is easy to overlook them. They may be looked for on the ledges 
and cuts in the mountain trails. They are too small to distinguish 
with the naked eye, so when I find a spot that looks “ suspicious ” I 
remove a bit of the earth or rock and take it home for further exami- 
nation. Out of every ten collections thus made, seven or eight will 
probably prove to be blanks, while the remaining lot will contain some 
of these tiny Cephaloziellas. 
It was my good fortune while at Santa Barbara to discover a fine 
lot of Frullania Catalinae Evans in full fruit. I am told that this is the 
third station to be reported for this fine species. I found it quite 
abundant, growing on several oak trees, but not knowing at the time 
the value of my discovery I neglected to seek further for it. Another 
species, Frullania Bolanderi Aust., I have collected occasionally in the 
San Gabriel Mountains at an elevation of 4000 feet. It grows on 
various trees but seems to prefer the live oaks. 
No list of hepatics would be complete without mentioning Mar- 
chantia polymorpha L. One lawn in the center of the city is thickly 
covered with this plant. Dr. Howe says in his book that he has not 
seen mature capsules of this hepatic in California, but these 
Pasadena plants have abundant fruit. 
This is not a complete list of Southern California hepatics, but 
merely a list of those species that I have found here during the past 
year. There are still several species to be looked for, especially those 
found in the higher mountains. 
In conclusion, I wish to express my thanks to Miss C. C. Haynes, 
Dr. Evans, and Dr. Conklin, for valuable aid in determining some of 
the specimens. Pasadena, California.
