plant, liable to be passed by, for its minute white flowers are not 
large enough to attract attention. Jepson does not record it 
from so far south, giving its range from “Oakland Hills and 
Marin Co. northward to Napa Valley and Mendocino Co.” 
CHEIRANTHUS CALIFORNICUS Greene 
Plants collected on the hills back of Alum Rock Park were 
referred to this species. So far as noticed, the flowers are bright 
orange with no indication of paleness in age as in the type, 
which had “flowers large, yellow, fading to cream color.” Our 
plant frequents gravelly hillsides in rather dry places, but ust- 
ally near trees. 
GUILLENIA LASIOPHYLLA (H. & A.) Greene 
This plant, formerly included under 7helypodium, is nct 
uncommon with us, being found occasionally on grassy banks. 
It was collected this spring in the hills back of Alum Rock 
Park growing near rocks. It is widely distributed in California, 
occurring even on the Mojave desert, and is quite variable. 
TILILAEA ERECTA H. & A. (7: minima Miers.) 
A little plant resembling somewhat the staminate flowers 
of the oak, the short stems only an inch or two high, commonly 
growing in tufts either on the ground or on rocks. It is fairly 
common everywhere in the hiils, but in 1904 was very abundant 
and luxuriant on burnt places southwest of Los Gatos. 
RIBES GLUTINOSUM Benth. 
Common in the mountains back of Saratoga at medium 
elevations. This may be easily distinguished from A. malvac- 
eum by its later blooming, much greater size, more branching 
habit, thinner leaves, and much larger cluster of redder flowers, 
the calyx segments merely spreading, not rotate. It often has 
a trunk nearly two inches in diameter with smooth gray bark, 
and is often eight to ten feet high. Originally collected by 
Douglas, probably near Monterey, it is found only in the coast 
region from Monterey north to Sonoma county.
