16 PITTONIA. 
7. A. HUMISTRATA. Stout and succulent, the branches 
mostly prostrate, a foot long, racemose throughout: pedicels 
short and stout, commonly deflexed : calyx lobes linear-spatu- 
late, in fruit greatly enlarged (4—6 lines long) and turned to 
one side, standing vertically in a row: corolla small; nutlets 
ovate lanceolate, 2-line long, straight, carinate ventrally down 
to the nearly or quite basal, rounded scar, the back with very 
minute muriculations and sharp-edged transverse rugule 
which commonly develope short and minute penicillate bris- 
tles.—Eritrichium Californicum var. subglochidiatum, Gray, 
Bot. Cal. i. 526 and Syn. Fl. 191 in part, also of Krynitzkia, 
l e. 266, but excluding the plant of the Rocky Mountain 
region. 
Frequent from San Diego throughout the State, growing in 
moist places, flowering in early spring, the branches in age 
becoming indurated. 
8. A.scoPULORUM. Much smaller and more slender than 
the last, but somewhat succulent, the branches depressed, 
1—6 inches long, leafy-racemose throughout, the floral leaves 
linear, elongated : segments of the calyx linear not accrescent, 
or turned aside: nutlet a half-line long, ovate-lanceolate, 
lightly carinate ventrally down to the almost basal, ovate scar, 
also dorsally toward the apex, the back otherwise muriculately 
or even somewhat penicillately roughened and rugulose, the 
rugule running well into favose meshes.— Eritrichium Cali- 
fornicum, var. subglochidiatum, Gray, l. c. (and Krynitzkia, 
l. e.) as to the plant of Colorado, Wyoming and Montana. 
. Very distinct every way from the last; far more like the 
next. 
À. PLEBEIA. Branches depressed, a span or more long : 
floral leaves linear-oblong : calyx slightly accrescent : nutlets 
ovate, a line long, carinate ventrally down to the ovate 
sear, the back rugose-reticulate, glabrous. —Lithospermum 
plebeium, Cham. & Schlecht. Linnea. iv. 446: Eritrichium, 
A DC.1. e 133; Gray L e; Krynitzkia, Gray 1. c.
