’ Lepidium bernardinum sp. nov. 
Root stout, perpendicular ; stem simple below, branched above, 
or in small specimens simple, 4-6 dm. high, pubescent below with 
short, deflexed hairs, puberulent above ; basal leaves oblanceolate, 
the blade toothed, 3-5 cm. long, tapering to a slightly longer, 
somewhat winged petiole, pubescent ; petiole ciliate on the mar- 
gin; stem-leaves narrowly oblanceolate, sessile, pubescent, toothed, 
those of the ultimate branches becoming entire and nearly linear ; 
sepals slightly exceeding I mm. in length; petals oblanceolate, 
scarcely equaling the sepals; silicels glabrous, 3.5 mm. broad, 
orbicular or slightly longer than broad, on slender, puberulent, 
widely spreading, terete pedicels, which are about 5 mm. long; 
cotyledons incumbent. 
A near relative of Lepidium medium, but readily distinguished 
by its pubescence, broader leaves, and larger silicels. 
Lepidium bernardinum is common in the coniferous forests of 
the southern California mountains. The type, which is deposited 
in the herbarium of the New York Botanical Garden, was collected 
by the writer (2826) in Bear Valley, San Bernardino Mountains, 
July, 1902. 
‘ Cercocarpus minutiflorus sp. nov. 
Shrub 2-2.5 meters high, with herbage glabrous throughout ; 
leaves obovate, cuneate at base, serrate-toothed on the rounded 
summit, I~2 cm. long, green and shiny beneath, thin; veins 3 or 4 
pairs ; petioles 4 mm. long ; pedicels slender, 7 mm. long; calyx- 
tube 12 mm. long (in young fruit), 1 mm. broad; calyx-limb 2 
mm. broad, minutely and very sparsely tomentulose, its lobes 
subulate-triangular. 
The small bright green leaves distinguish this species at once 
in the field. The minute calyx-limb with its almost subulate lobes 
are, also, quite unlike the silky-tomentose calyx-limb and broadly 
triangular lobes of C. detulacfolius. 
This species belongs to the chaparral belt of southwestern San 
Diego County, where it seems wholly to replace C. detu/acfolius.
