herbaceous, much branched, 5° high; stem smooth; stipules falling away 
very early ; leaves deeply 3-parted, with the divisions lanceolate, tapering 
into along point; bracts three times as long as the truncate cyathiform calyx ; 
petals very delicate rose color, 1’ long, obovate, woolly at the base on mar- 
gins; style longer than the stamineal column. Young branches, petioles, 
leaves, and flowers sprinkled abundantly with black dots. (698.)' Sanoita

STERCULIACE4.+ 
AyentAt pusitua, L., var. ramis erectis, foliis superioribus lanceolatis, 
Gray (Pl. Wright. 1, p. 24)—Perennial, with many thin, wiry stems from 
the thick, woody root; lower leaves ovate and somewhat irregularly serrate, 
upper ones irregularly serrate, twice as long, and lanceolate; flowers small, 
on reflexed, filiform pedicels, which are 2-4” long; capsule tuberculated 
and hairy. I would call attention to the fact observed by Dr. Gray (PI. 
Wright. 2, p. 24), that the anthers are trilocular. Judging from the state- 
ment in Bentham and Hooker, Gen. Plant. vol. 1, p. 225, this would also 
appear to be the usual rule in the genus. My specimens (569) from South- 
ern Arizona correspond exactly with those obtained by Dr. Thurber at Van 
Horn’s Wells, in what was then Sonora. 
LINE. 
Linum rieipum, Pursh, var. puberulum, Gray (Pl. Wright. 1, p. 25)— 
Low, 2’—4’ high, annual, branching from near the base; stems decidedly 
puberulent, leaves less so; leaves slightly imbricated, 3-6” wide, lower 
obtuse, upper slightly mucronate; vein inconspicuous ; pedicel very slightly 
thickened at the top (not, however, forming a cupule); sepals acute, 
mucronate, glandular hispid on the margin; central vein prominent, and on 
outer (sepals) the lateral ones inconspicuous, a little longer (3-4” long) 
than the mature capsule (sepals about equal in length to the nearly undi-
