CAEYOPHYLLE^E. 37 



leaves narrowly linear or subulate, acute or mucronate, J£ — % in. long; 

 stipules lanceolate, acuminate, 1 — 2 lines long: pedicels slender, 2 — 3 

 lines long: sepals oblong, obtuse, scarious-margined: petals reddish, 

 about equalling the sepals: capsule ovate, obtuse, not exserted: seeds 

 brownish, tuberculate, wingless, triquetrous-obovate, ,with a marginal 

 elevation. — Roadsides; frequent, and sometimes perennial. April — Oct. 



6. T. marina (Wahlb.), Britt. Root thickish, not much branched, 

 sometimes- perennial: stems ascending, 3 — 8 in. high, somewhat com- 

 pressed or angular, glabrous or somewhat glandular-pubescent: leaves 

 semilerele, narrowly linear, acute, light green, glabrate, seldom exceeding 

 the internodes; stipules broadly ovate, abruptly acuminate : cymes 

 scarcely leafy: pedicels about twice as long as the capsules: sepals acute 

 or acuminate, with a broad or narrow scarious margin : petals broadly 

 ovate, obtuse, scarcely equalling the sepals, whitish or pale rose-color: 

 capsule ovate, obtuse, nearly twice the length of the calyx: seeds orbicular, 

 with an elevated margin, reddish-brown, smooth, winged or wingless. — 

 Common and variable, occurring mostly near the sea. 



7. T. salina (Presl.), Britt. Roots slender and tufted, simple or 

 much branched: stems 6 in. high, much branched, usually ascending, 

 rarely divaricate and prostrate: herbage glabrous or pubescent: leaves 

 flat, linear-filiform, obtuse or acutish, glabrous, light or livid green, sel- 

 dom longer than the internodes; stipules broadly ovate, short-acuminate, 

 not shining: pedicels leafy-bracted, or the upper bractless, none of them 

 longer than the capsules: sepals oblong or oblong-ovate, obtuse, scar- 

 ious-margined: capsule acute, much longer than the calyx: seeds round- 

 obovate, tuberculate or muriculate, the marginal elevation distinct; hyaline 

 wing narrow or wanting. Var. sordida, Greene. Stems ascending; 

 herbage very viscid and hairy; fl. in unilateral leafless racemes: seeds 

 nearly black, sharply muriculate, wingless. Var. Sanfordi, Greene. 

 Stems erect repeatedly dichotomous: herbage scarcely viscid and only 

 slightly pubescent: inflorescence partly dichotomous, only the ultimate 

 branchlets unilaterally racemose: seeds dark brown, nearly smooth, 

 wingless. — Common on the seaboard. The first variety is very abundant 

 in low rich soil above the salt marshes on the " Island," near Alameda. 

 The second belongs to the plains in the interior. March — May. 



9. T. tennis, Greene. Slender, prostrate, very diffuse, the whole 

 plant 1 ft. broad, glabrous, or the inflorescence sparsely glandular- 

 pubescent: leaves linear-filiform, 1 in. long, equalling the internodes; 

 stipules broader than long, acute, but small and inconspicuous: fl. very 

 numerous, crowded and often subsessile on the countless dichotomous- 

 cymose branchlets, apetalous: stamens 2: capsule triquetrous, acute, more 

 than twice the length of the oblong obtuse scarious-margined sepals: seeds 

 reddish brown, obliquely obovate, compressed, smooth, margined, wing- 

 less. — Alameda.
