grounds in the valleys to their summer ranges in the mountains, 
sometimes in small parties, sometimes singly, and owners of these 
animals say they manifest much uneasiness and are held with diffi- 
culty when the time approaches for the spring drive. The first cool 
storm in fall is likely to start them down the mountains to their 
winter ranges again. They sometimes make a considerable part of 
these journeys during the night. 
NOTES ON THE NATURALIZED PLANTS OF 
“SOUTHERN CALIFORNIA, III. 
BY::5,:B, PARISH. 
Some additions to our naturalized flora might reasonably be ex- 
pected from Chinese sources. These people began to arrive soon 
after gold was first discovered here, and have penetrated to all parts 
_ of the state; they are largely engaged in occupations connected with 
the soil, as gardening, mining and grading; they camp along the 
lines of new railways, and occupy the neglected outskirts of towns, 
and wherever they may be they are supplied with many articles im- 
ported from their native country. Under these favoring conditions 
doubtless some Asiatic plants have escaped here and there, yet there 
has been recorded only a single species,* a grass which was perhaps 
a mere waif. 
Among the plants most likely to reach us through these influences 
Sagittaria Chinensis is to be expected. Its tuberous roots are used 
as an article of diet, and always occupy a prominent place in the 
collection of strange delicacies which the Mongolian grocer sets forth 
to tempt the appetites of his customers. As sold they are in an 
entirely fresh state, and if planted in damp soil grow as readily as a 
potato. 
Last summer for the first time I found this Sagitiaria growing on 
the banks of Warren Creek, a stream which flows by the ‘‘ Chinatown” 
of San Bernardino. There were two clusters at places about a mile 
apart. Each consisted of some twenty or more plants, and had 
probably established themselves the year before. ‘The severe floods 
of last winter covered one of these Stations. under a sand-bar, while 
the other was ravaged by Chinamen, but despite these drawbacks 
plants have reappeared this summer at both places, as well as at in-
