296 MuNz AND JOHNSTON: PLANTS OF SOUTHERN CALIFORNIA 
In the San Bernardino Mts. about the crest of Mt. San 
Gorgonio, at altitudes from 11000 to 11700 ft., the var. austro- 
montanum becomes consistently much reduced in stature, having 
stems only 1-2 cm. high. This form, typified by Munz 6208 
(Baker Herb. 12844), may be known as the forma alpigenum. 
¥ Malvastrum clementinum sp. nov. 
A rounded tufted shrub with many ascendingly branched 
stems 7-10 dm. high; stems rather coarse, tomentose when young; 
leaves angularly 3-lobed or orbicular or ovate, 3-5 cm. broad, 
base cordate, margin irregularly crenate, upper surface green 
but with a very sparse stellate pubescence, under surface canes- 
cent with a dense stellate tomentum, veiny; flowers many, 
subsessile and densely glomerate in the axils of the uppermost — 
leaves and continuing out into an elongate naked interrupted 
spike 1-2 dm. long; calyx 7 mm. high, loosely stellate-tomentose;

Los ANGELES spent On walls of the ao rtinning into 
the sea from Lemon Tank, San Clemente Island, April 9, 1923, 
Munz 6684 (TYPE, Baker Herb. 20491; 1sotyPE, Gray Herb.). 
This beautiful Malvastrum was found to be occasional in 
rock-crevices and at the base of rocky walls of a very precipitous 
canyon on the northeast side of San Clemente Island. It is 
characterized by its pale dense stellate pubescence with long 
trichome-branches, by its conspicuously bicolored leaves, and 
by its very dense interrupted spicate inflorescence. It suggests 
typical M. fasciculatum (T. & G.) Greene in the contour of its 
bicolored leaves, but differs in its much looser pubescence of 
long whitish hairs, in its more crowded flowers, more deeply 
lobed and more loosely pubescent calyces, and very much longer 
bractlets. From M. Fremonti Torr. and allies, which it suggests 
in its loose tomentum and interrupted congested spikes, it differs 
in its longer pubescence, bicolored leaves, and longer bractlets. 
Malvastrum nesioticum Robins., an endemic of Santa Cruz 
Island, differs from M.clementinum in the characters enumerated 
for M. fasciculatum, and furthermore, like M. fasciculatum var.
