gular, bristle-pointed, more or less scarious-margined and remotely den- 

 ticulate, i-nerved, the base of the mid-rib callous, without stipular glands ; 

 pedicels about equal to the Howers; sepals broadly ovate, somewhat 

 acuminate, bristle-pointed, more or less evidently i-nerved, with broad 

 scarious subentire or glandular-ciliate margins, persistent: petals pale, 

 obovate-cuneate, (8-10 mm. long,) two or three times as long as the calyx, 

 bearded just above the base ; stamens and pistil of equal length, about 

 as long as the sepals; styles distinct only at the apex; capsule globose- 

 ovoid, about as long as the calyx, the false septa entirely membranaceous. 

 — Texas. 



* * * Estipulate or with stipular glands ; pedicels often elongated ; flowers medium sized 

 or mostly small, yellow, white or rose-purple; sepals usually glandular-ciliate, 

 persistent; petals commonly with lateral teeth and 1-3 ventral appendages at 

 base; filaments without intervening appendages, but sometimes 2-toothed at base; 

 carpels 2-3, without cartilaginous insertions; styles distinct ; stigmas small, ob 

 lique, or subcapitate; capsule with firm septa, long-ciliate at base, the false parti- 

 tions mostly incomplete ; seeds mostly plump ; annuals. — § Hcsperolinon. 



13. L. DiGYNUM, Gray, Proc. Amer. Acad. vii. 334. — About a spart 

 high, glabrous; stems slender, several times forked, rather prominently 

 angled above; leaves mostly opposite, elliptical-spatulate, the lower 

 obtuse and entire, the upper acute or mucronate and remotely serrulate,^ 

 somewhat 3-nerved (2-3 X 7-10 mm.), without stipular glands ; flowers at 

 length loosely corymbose or subracemose, small, yellow; pedicels shorty 

 about equal to the flowers; sepals ovate-oblong, rather obtuse, somewhat 

 faintly 1-3-nerved or keeled at base, minutely senulate, glandular and 

 lacerate below, two of them mostly conspicuously longer and very blunt; 

 petals spatulate-oblong, truncate or emarginate, neither toothed nor 

 appendaged, about 3 mm. long, one-half longer than the sepals; stamens 

 and pistil a little shorter than the calyx ; carpels 2 ; capsule a little shorter 

 than the calyx, ovoid, slightly retuse at apex, somewhat rough, com- 

 pletely 4-celled, the walls and septa rather thick; seeds .5-1 mm. In habit 

 resembling a small form of L. Virginia7ium. — Washington {Suksdorf), 

 Oregon (^Ho-mcU, Mrs. Summers), and Northern California {Bolander, 

 4900; Greetie, Lemmon). 



14. L. DRYMARioiDES, Curran, Bull. Calif. Acad. No. i. 152. — A span 

 or two high, sparingly white-villous ; stems rather coarse at base, repeat- 

 edly dichotomous, with long slender internodes; leaves opposite or sub- 

 verticillate below, broadly ovate, acute or acuminate, with short crowded 

 marginal glands, rather loose-veined, (4-6X5-10 mm.), the upper much 

 reduced; flowers small, rose-colored, scattered along the ultimate branch- 

 es; pedicels mostly short; sepals lanceolate, acute or submucronate, 

 minutely serrulate, their margins sometimes glanduliferous; petals ovate, 

 emarginate, 2-toothed and 3-appendaged at base, the median appendage 

 rounded and glabrous; stamens and pistil about equal to the calyx; cap- 

 sule ovoid-acute, about as long as the calyx, 6-valved, the false septa
