* Outer sepals provided with lateral teeth. 

 ' L. Texana, Hook. Branching from near the base : branches 4-G 

 inches long : flowers chiefly borne upou short secund and somewhat 

 recurved branchlets : sepals straight or slightly curved : stamens in 

 the flowers examined 3 (5 according to Honk, and Gray) : seeds 

 rather broadly obovate. — Icon. t. 285 (text with t. "27.")). Brandegee, 

 Zoe, i. 219. L. squarrosa, Ton*. & Gray, Fl. i. 674 ; Gray, Gen. ii. 23, 

 t. 106 (Figs. 7 and 8 represent the seed too narrow and with cotyle- 

 dons incumbent instead of accumbent as is the case) ; Coult. Man. of 

 S. W. Tex. 31. — Central and Eastern Texas, Drummond, Wright, 

 Hull; differing slightly, but as it appears constantly, from the 

 following. 



Li. squarrosa, Nutt. Smaller, 2-4 inches high : branchlets 

 scarcely or not at all secund: sepals pretty strongly recurved and 

 squarrose : stamens 3 (—5?): seeds oblong or elliptical in outline. — 

 Torr. & Gray, Fl. i. 174; Brew. & Wats. Bot. Calif, i. 72; Wats. 

 Bibl. Index, 104 (excl. syn.) ; Brandegee, 1. c. 219. — Sandy soil, 

 California, San Diego northward to Sierra Co., Lemmon. 



* * Sepals all entire. 



L. pusilla, Curran. Low and condensed, 2-3 inches in height ; 

 branches closely flowered, not distinctly secund : sepals lanceolate, 

 acute and bristle-tipped: stamens (in flowers examined) 3. — Hull. 

 Calif. Acad. i. 152 ; Brandegee, Zoe, i. 220. — Tehachapi, California, 

 4,000 ft, Mrs. Curran. — This very interesting species has the calyx 

 of a Cerdia, but is distinguished from that genus by the number of 

 stamens, the absence of a style, and the accumbent position of the 

 cotyledons, which in Cerdia appear to be constantly incumbent. 



18. STIPULICIDA, Michx. (Name from the Latin stipula, 

 stalk, blade, stipule, and ccedere, to cut, from its deeply divided 

 stipules.) — A monotype, scarcely differing in its technical char- 

 acters from the Old World Polycarpcea, but with a very distinct 

 habit, somewhat that of an Eryogonum. — Fl. i. 26, t. G; Gray, Gen. 

 ii. 25, t. 107. 



S. setacea, Miciix. I.e. A span high: root simple: the stem. 

 dichotomously forked: radical leaves spatulate, 2-4 lines long, nar- 

 rowed to a slender petiole: flowers small, fascicled at the ends "I 

 the naked branches.- Chapm. Fl. 47. Polycarpon stipulicidum, 

 Pers. Syn. i. Ill; Pursh, Fl. 90. — Sandy soil, North Carolina to 

 Florida.
