226 PITTONIA. 
coarsely toothed, 3 inches long, the rameal ones shorter, 
dilated below and sagittate-clasping: racemes elongated, the 
whitish flowers on very short pedicels: sepals subequal, 
obtuse, none saccate at base, all earinately 1-nerved, glabrous: 
petals all with broad claw and rather narrow limb, very un- 
equal, the upper pair much longer: upper pair of filaments 
exserted, united almost throughout and with small abortive 
sterile anthers, the other stamens very short, scarcely ex- 
serted: pods 2 inches long, ascending or suberect, rather 
broadly linear,carinate-nerved : seeds suborbicular, narrowly 
winged. 
Mt. St. Helena, Calif., June, 1894. Collected only by the 
author. 
STREPTANTHUS FOLIOSUS. Annual(?), tall and branching, 
glabrous and glaucous: lower leaves and main stem un- 
known, the mere flowering branches 1 to 14 feet long, very 
copiously leafy or leafy-bracted, the leaves or bracts from 
oblong-obovate to orbicular, the lower and elongated ones 
saliently dentate, the upper and rounded entire, mucronate, 
these producing from their axils similarly round-bracted 
branchlets each terminating in short sessile dense speciform 
raceme of large white flowers: sepals thin, subequal, two 
slightly saccate, the tips of all rather amphiate and recurved : 
petals narrow and inconspicuous: stamens all with exserted 
linear stigmas, and their filaments distinct. 
The fragmentary though large specimens indicating à 
strongly marked species of the S. tortuosus group have been 
in my herbarium some eight or nine years. I had hoped 
to obtain fruiting specimens, as well as some data regarding 
the root and lower leaves before publishing ; but the remote 
and scarcely explored parts of the Californian mountains (of 
Fresno County) whence the fragments were brought to me 
are still unvisited by any botanist. The short sessile spikes 
at the ends of branchlets, upon which the round cordate- 
clasping bracts are quite crowded, are in striking contrast 
with the inflorescence of every other known Streptanthus. —
