164 New Species of Lower California Plants. [ZOE 
This tree-composite is abundant in some parts of the Cape Re- 
gion, especially so about Todos Santos. I have collected it often 
in unsatisfactory condition, and now Dr. Purpus has sent fine 
specimens. 
Stephanomeria Guadalupensis. Perennial, growing in clumps 
3-4 dm. high; leaves densely covered with white wool, especially 
below, becoming glabrous with age, 15 cm. long, 5 cm. wide, 
pinnately parted into rounded lobes; flowering stems 3-4 dm. 
high, striate; bracts woolly; branches of the panicle short; invo- 
lucre calyculate at base, the scales 7-8 mm. long; heads about 1o0- 
flowered; pappus of 10 or more bristles, plumose nearly to 
the base. 
Collected on Guadalupe Island in Sparmann’s Cafion, March 
26, 1897. The clumps of white leaves growing on the nearly 
perpendicular dark-colored cliffs are very conspicuous. The only 
fruiting heads collected were remnants from the preceding season. 
Diospyros TEXxANA Scheele, var. Californica. A small tree 
4-6 m. high; leaves 6-7 cm. long, glabrous or pubescent, rounded 
or cuneate at base, sometimes retuse at apex; fruit 2-3 cm. in 
diameter. 
The native persimmon of the Cape Region of Lower California 
agrees with D. Zexana in nearly all respects, differing only in 
the larger size of the leaves and fruit, and from descriptions of 
the Texas species, seems to be more arborescent. ‘The leaves are 
very variable in shape and pubescence. 
ROTHROCKIA CORDIFOLIA Gray. This is a common plant of 
the Cape Region. ‘The lobes of the corona, as well as the ap- 
pearance of the produced stigma, are very variable. ‘The corona 
lobes sometimes appear as if joined about their center to the sta- 
men tube or corolla. Below the junction and on the sides the 
lobes are thick and fleshy with the free edges indistinctly crenate, 
above they are thinner and the upper edge is sharply 2-toothed 
near the middle, there are also two lateral teeth more or less de- 
veloped. In one flower examined some of the corona lobes lacked 
the thickened, free margin of the base. At the side and base of 
the lobe, the fleshy free margin often stands out as an auricle.
