332 PITTONIA. 
reniform-hastate to narrower and subsagittate, rather prom- 
inently and sharply mucronate: peduncles short, about 
equalling the short-petioled leaves, 1-flowered ; calyx sub- 
tended by a pair of narrowly elliptic bracts at a short dis- 
iance below it, their tips either reaching the bases of the 
sepals, or longer and partly embracing them: sepals very . 
unequal, the outer often broadly ovaland truncate and only 
half the length of the innermost, these being much narrower, 
and from obtuse to acute: corolla an inch long or more, 
yellowish ; the narrowly linear stigmas much or little sur- 
passing the anthers. 
Very common species of northern California and southern 
Oregon, among the hills and on the plains; appearing in 
such diversity of form as to indicate the possibility of more 
than one species; for the distinguishing of which, however, 
no constant characters are to be found in the dried speci- 
mens. Mr. Howell’s n. 1948, from near Roseburg, Oregon, 
differs from the more typical Californiau plant in that its 
leaves are broader and nearly glabrous; its sepals, though 
very unequal, are all broad, truncate and mueronate, and 
it has a more elongated style. 
C. PURPURATUS. C. luteolus, var. purpuratus, Greene, 
Man. 265 (1894). Suffrutescent, or even shrubby, with long 
naked grape-vine-like woody stem, the leafy and flowering 
branches mantling the summits of small trees: herbage 
glabrous: peduneles mostly bearing a cyme of several 
flowers, both the evme itself and each individual peduncle 
bearing a pair of linear or lanceolate herbaceous bracts: 
limb of corolla (pink, purple or dull creamy white) with 
entire and perfectly circular limb. 
Common along the seaboard in middle California, espe- 
cially about San Francisco Bay. In open dry ground ~ 
usually trailing over rocks and bushes, and merely suffru- 
tescent; but in groves and along streams, large, Dg 
climbing and vine-like.
