L. multicaule, Hook. Annual?, more or less puberulent : leaves very narrow, mostly 

 linear, awn-pointed, less than 3 lines long, 1-nerved below, often revolutely concave, fre- 

 quently ciliate, the upper often scarious-margined : flowers mostly few, terminating the 

 branches : sepals ovate, abruptly bristle-pointed, more or less evidently 1-nerved, with broad 

 scarious often subentire margins : petals 4 or 5 lines long, deeper colored at base : capsule 

 about as long as the sepals. — Hook, in Torr. & Gray, Fl. i. 678; Planch. 1. c. vii. 185;

 small, yellow, white, or roseate : sepals usually glandular-ciliate, persistent : petals com- 

 monly with lateral teeth and 1 to 3 ventral appendages at base : filaments sometimes 

 2-toothed at base, otherwise unappendaged : carpels 2 or 3, without cartilaginous inser- 

 tions ; styles distinct ; stigmas small, oblique or subcapitate : capsule very small (scarcely 

 a line long), separating into twice as many valves as there are carpels, with firm septa 

 long-ciliate at base ; seeds mostly plump, small : mostly forking slender annuals, of the 

 Pacific Coast. — § Hesperolinon. 



•f— Carpels 2 : false septa complete : petals yellow, not appendaged. 



L. digynum, Gkat. A span or less high, glabrous, somewhat glaucous : stems slender, 

 striate, mostly simple below, several times corymbosely forked above, without stipular 

 glands : leaves usually opposite, elliptic-spatulate, the larger 5 lines long, 1- or obscurely 

 3-nerved, the lower entire and obtuse, the upper serrate, acute or mucronate : flowers sub- 

 racemose or loosely corymbed, short-pedicelled : sepals very unequal, ovate-oblong, obtuse, 

 glandular-serrulate or lacerate, 1- to somewhat obscurely 3-uerved at base : petals 1^ lines 

 long : capsule ovoid, slightly retuse at apex, a little shorter than the calyx. — Proc. Am. 

 Acad. vii. 334; Brew. & Wats. Bot. Calif, i. 89; Trelease, 1. c. 17. — Washington to the 

 mountains of Central California. A small plant of the aspect of L. catharticum. 



•t- -I— Carpels 3 : false septa incomplete : petals mostly appendaged. 



++ Leaves glandular-denticulate : no stipular glands : false septa narrow. 



L. drymarioides, Curkan. a span or two high, sparingly white-villous : stems rather 

 coarse at base, repeatedly dichotomous, with long slender internodes : leaves opposite or 

 the lowest subverticillate, broadly ovate, the larger 5 lines long, rather loosely veined, acute 

 or acuminate, with short crowded marginal glands : flowers roseate, scattered along the 

 branches, mostly short-pedicelled : sepals lanceolate, acute or mucronate, minutely serrulate 

 and occasionally glandular-ciliate, 1-nerved : petals minute, 2-toothed and appendaged at 

 base, the median appendage rounded and glabrous or sometimes wanting : capsule ovoid, 

 acute, as long as the calyx. — Bull. Calif. Acad. Sci. i. 152 ; Trelease, 1. c. — Lake County, 

 California, Mrs. Curran. 



L. adenoph^llum, Gray. A span to a foot high, glabrate or somewhat villous, espe- 

 cially Just above the nodes : stems slender, repeatedly forked, striate : leaves alternate or 

 the lowest opposite or in threes, remote, very narrowly oblong, less than an inch long, 

 folded along the midrib, obtuse, somewhat cordate, 1-nerved, closely and conspicuously 

 glandular-denticulate : flowers yellow, terminating the branches, slender-pedicelled : sepals 

 lanceolate, acute, usually minutely glandular-denticulate, 1-nerved : petals 2 or 3 lines
