FURTHER ADDITIONS TO THE FLORA OF 
SOUTHERN CALIFORNIA. 
By S. B. Parisz. 
Within the last few years several lists have been published 
of additions to the Flora of the southern counties of the 
State, but our knowledge of it is yet far from being complete. 
Other plants, before undetected, continue to be discovered 
in our region, and in the present paper I wish to make a 
record of some of them. 
When it is considered that, owing to the peculiar climatic 
conditions here existing, the Flora, far from being homo- 
enous, presents a constant variation, so that in whatever 
geographical direction exploration is pursued, plants of one 
area are successively disappearing and those of another tak- 
ing their places, and that while much of the ground has been 
quite thoroughly gone over, an inviting portion yet remains 
which has received only a cursory examination; it is reason- 
able to expect that very considerable further additions will 
be made to the number of plants now known. Those already 
reported number almost twenty-one hundred species and 
varieties of flowering plants. With a more complete knowl- 
edge of the entire district, it will probably be found that not 
less than twenty-five hundred seed- bearing plants grow 
within its limits. 
Those named in the following list, not otherwise credited, 
were collected by the writer. Those designated by an * 
have not before been reported from this State. My thanks 
are due to the botanical authorities who have passed upon 
some difficult species, and to the correspondents who have 
favored me with valuable specimens.

only phyllodia and a few immature leaves had been formed,
