ever, it exhibits certain marked peculiarities, and a series of 
specimens enable me to describe it as 
Ruvus TriLopatTa, Nutt., var. quinata. Lateral leaflets 
broadly ovate or obovate, crenate above or 3-lobed, at base 
obtuse or cuneate or even strongly oblique; terminal leaflet 
3-cleft, -parted or -divided, the terminal division 3-lobed and 
sparingly crenate, the lateral divisions similar in size and 
shape to the lateral leaflets—the leaves thus simulating the 
quinate. 
The pulp of the viscidly pilose scarlet fruit is thin with 
longitudinal fibres of a resinous texture, two of these on the 
edge of the flattened smooth stone are conspicuously free and 
attached at the summit of the drupe to the epicarp. This 
character, however, is not peculiar to this variety but is found 
in various Pacific Coast forms of the species.

ALIEN Puants IN Canirornia.—It is well known to field 
botanists in California that many native plants are being 
slowly crowded out chiefly through the growth of the agri- 
cultural and horticultural interests. It is noticeable in the 
first place in the reduced size of various species as well as 
fewer individuals. Specimens of Linanthus androsaceus are 
hardly half as large as those collected ten or twenty years 
ago. And so with many other Polemoniacex. Well marked 
local forms of Eschscholtzia, perhaps not even worthy of 
varietal names so far as classification goes, have been in cer- 
tain instances entirely driven out. 
In this process of extermination of native plants foreign 
weeds also play a part, for many native annuals are too feeble 
to resist the hardy invaders. It is true that many immigrant 
plants, notwithstanding the favorable conditions, do not 
spread, and a few survive only for a time. It is likewise 
true that others take absolute possession of large areas. The 
behavior of foreigners on our soil should in all cases be care- 
fully observed and will form a distinct contribution to the 
botanical history of the State. The possibilities of further
