302 PITTONTA. 
10. PUMILA. Rigidly shrubby and intricately branched dwarf, 
apparently 8 or 10 inches high including the small pods all 
on terminal peduncles: leaves ovate-lanceolate to elliptic, acute 
by a recurved mucro, } to } inch long, pale, reticulate, the 
veins and meshes on both faces minutely scaberulous: corolla 
ä inch wide: pods 1 to 13 inches long. 
Mt. St. Helena, Napa Co., Calf., April, 1889, T. S. Brandegee ; 
type in U. S. Herb. This interesting dwarf is guessed by me 
to have come from perhaps the very summit of this culminating 
point of the middle Californian Inner Coast Range. The knotted 
and gnarled lower branches bear lichens in evidence of the under 
shrubs’ inhabiting a height where the summer fogs, which pre- 
vail in the coast ranges, come early in the day and stay late. 
. D. LEIOPHYLLA. Leaves coriaceous on mature branches, 
si: iot very rigid, ascending, 1} to 24 inches long, rather 
broadly elliptic-oblong, mucronate- -acute, entire, or now and 
then with some obscure denticulation, only two lateral veins 
manifest and these more or less tortuous as partially circum- 
scribing the coarse and altogether faint low smooth reticula- 
tion; leaves of young plants much thinner and larger, oval, 3 
inches long, 2 in breadth, showing usually a few coarse serrate 
teeth towards the apex, the feather-veins more numerous if not 
more distinct, the reticulation not formed, only foreshadowed 
by various delicate elevated lines; buds globose: corolla 13 
inches wide. 
Fine species of the Sierra N evada, represented in U.S. Herb. 
ve a specimen from Cherokee, Butte Co., by Mrs. Bidwell, May, 
, and two from near Alta, by Brandegee, July, 1889, one 
a these from a robust seedling, showing the toothed foliage 
mentioned by Brandegee in Zoe, i. 47, whose account of e 
young seedling plants, by the way, is one of the most intere 
facts hitherto published concerning this remarkable genas. 
In so far as I know, Mr. Brandegee is the only one who has 
seen thé cotyledons of Déndromecon.
