 and Mendocino Counties. 



++ ++ Leaves entire, without marginal glands, alternate except sometimes at the very 

 base : false septa widened below. 



= False septa complete below : flowers yellow or yellowish. 



Li. Clevelandi, Greene, a span to a foot high, glabrate, repeatedly dichotomous : 

 leaves oblong, 5 lines long, 1-nerved, subacute, without stipular glands : flowers minute, on 

 filiform pedicels (sometimes an inch long) : sepals narrow, acute, sparingly glaudular-ciliate : 

 petals yellow or pale, a line long or less, 2-toothed, 3-appendaged, the median appendage 

 oblong, glabrous : capsule ovoid, acute, somewhat longer than the sepals. — Bull. Torr. 

 Club, ix. 121 ; Trelease, 1. c. — California, Lake and Mendocino Counties. 



= = False septa not reaching the axis except in the last species : flowers white, roseate, 

 or purplish. 



a. Loosely branched, the flowers slender-pedicelled. 



L. micranthura, Gray, a span to a foot high, of the aspect of the preceding, glaucous, 

 somewhat soft-pubescent toward the base of the slender nearly terete branches, loosely 

 dichotomous : leaves alternate, spatulate-oblong, 3 to 7 lines long, 1-nerved, obtuse or sub- 

 acute, mostly with stipular glands : flowers white or faintly roseate, considerably exceeded 

 by their slender straight pedicels : sepals ovate-lanceolate to oblong, subacute, the inner 

 sparingly glandular-ciliate : petals 1 to occasionally 2^ lines long, 2-toothed, mostly unappen- 

 daged : capsule ovoid, acute, about equal to the sepals. — Proc. Am. Acad. vii. 333 ; Brew. 

 & Wats. Bot. Calif, i. 90; Trelease, 1. c. 18. — Oregon to the vicinity of San Francisco, 

 California. 



L. spergulinum, Gray. Similar to the last and perhaps scarcely separable : leaves linear, 

 5 to 10 lines long, with or without stipular glands: flowers roseate, somewhat nodding on 

 filiform pedicels (occasionally 7 lines long) : petals 2 to 4 lines long, 2-toothed, 3-appendaged, 

 the median appendage ligulate and the lateral sometimes greatly reduced : capsule ovoid, 

 acute, nearly twice as long as the sepals. — Proc. Am. Acad. vii. 333 ; Brew. & Wats. Bot. 

 Calif, i. 90; Trelease, 1. c. 19. — Central California. 



b. Often more corymbose, the short-pedicelled flowers rather closely clustered at ends of the 

 branches. 



L. Calif ornicum, Benth. Somewhat taller, glaucous, glabrate or sparingly puberulent 

 near the nodes, loosely dichotomous, with angled or striate branches : leaves linear, 5 to 15 

 lines long, rather obtuse, with prominent stipular glands : flowers pale or roseate : sepals 

 lanceolate, acute, keeled below, glabrous, rather thick, with pale sparingly glandular-ciliate. 

 inner margins : petals 2 to 3 lines long, 3-appendaged, the median appendage rounded 

 hairy : capsule ovoid, acute, a little shorter than the sepals. — PI. Hartw. 299 ; Gray 

 Proc. Am. Acad. vi. 521; Brew. & Wats. Bot. Calif, i. 90; Trelease, I.e. — California, 

 Butte and Colusa Counties to the region east of San Francisco. When low, leafy, and with 

 rather dense inflorescence, it is the scarcely separable var. confertum. Gray in Trelease 

 1. c, of the San Francisco region, to which pertains the type of L. Breweri, Gray, Proc. Calif 

 Acad. Sci. iii. 102, & Proc. Am. Acad. vi. 521, from the Mt. Diablo Range, Brewer, 1181 

 the flowers of which are described by error as golden. 



L. COngestum, Gray. From less than a span high to stout and tall : stem glabrous, glau- 

 cous, striate below, with corymbose angled branches at top : leaves mostly somewhat pubescent, 

 linear-lanceolate, 3 to mostly 10 or 15 lines long, acute, with stipular glands : flowers rose- 

 purple, in glomerate clusters terminating the branches : sepals ovate-lanceolate, acute, con 

 spicuously pubescent : petals 3 to 4 lines long, 2-toothed, 3-appendaged, the median appen 

 dage elongated, somewhat hairy : capsule short-ovoid, nearly as long as the calyx, the fal.'^e 

 septa complete near the base. — Proc. Am. Acad. vi. 521 ; Brew. & Wats. Bot. Calif, i. 90 

 Trelease, 1. c. 20. — California, in the region adjacent to San Francisco.
