176 PITTONIA. 
21. P. commrxtus. More slender than the two foregoing, 
the pubescence copious, soft, spreading: corolla 1 inch 
broad, the cuneate-obovate petals apparently yellow: fila- 
ments not very unequal, spatulate-oblong, the outer obcor- 
date under the anther: carpels 12, at first concealed by a 
dense coat of appressed coarse-villous or hirsute hairs, in 
maturity little more than an inch long including the long 
and slender stigmas, rather strongly hirsute with ascending 
hairs: joints about 7, somewhat turgid, obtusely carinate 
and rugulose-roughened. 
This, together with the last two, were pressed together in 
a bunch, and fastened down as one specimen, on sheet n. 
2755 of Herb. Calif. Acad. All were collected in Lake Co., 
or perhaps Colusa Co., and in the same vicinity doubtless. 
Perceiving in the bunch three specimens of as many dis- 
tinct species, I separated them, leaving P. contortus on the 
original sheet. 
22. P. conrinis. Short leafy branches stoutish, decum- 
bent: leaves 2 inches long, oblong-linear, obtuse : scapiform 
peduncles stout, erect, 8 to 10 inches high, rather softly hir- 
sute with spreading hairs: corolla rotate, about 1 inch 
broad, cream-color, the petals broadly obovate: stamens 
very many, extremely unequal, the outermost series of less 
than a fourth the length of the innermost, their broad fila- 
ments not longer than the anthers, these in all nearly ob- 
long and short for the genus: fruit cylindric, naked, the 
petals and stamens being deciduous, carpels 9 to 12, merely 
torulose, loosely villous-hirsute: stigmas uncommonly thick 
and short for the genus, lanceolate, densely pubescent. 
Known only in a single specimen sent to the U. S. Herb. 
by J. W. Toumey, from the Bradshaw Mountains, Arizona, 
17 June, 1892.
