well as its upland habitat mark it as wholly distinct from all others in 

 our district. Apr. — June. 



* * Annuals; flowers usually lilac or loA'ender-color. 



5. T. EUBRA, Britt. Bull. Torr. Club, xvi. 126 (1889) ; Linn. Sp. PI. 

 i. 423 (1753), under Arenaria; Fries, Fl. Hall. 76 (1817), under Lepigoniim. 

 Stems slender, terete, prostrate, a few inches long, glabrous below, 

 pubescent and more or less glandular above : leaves narrowly linear 

 or subulate, acute or mucronate, ^4~^2 ^^- 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 

 above Petaluma, collected by the author in September, 1888. Doubt- 

 less introduced from Europe, where it is common in many districts, 

 chiefly at some distance from the sea. It was also found in the interior 

 of Oregon, in the summer of 1890. 



6. ? T. aiandra, Britt. 1. c. 128 ; Guss. Prodr. Fl. Sicul. i. 515 (1827), 

 under Arenaria. A. saUuginea, Burge, in Ledeb. Fl. Alt. ii. 163 (1829). 

 Near T. rubra, but more slender ; stipules very short ; cyme leafless and 

 widely divaricate, more profusely flowering ; capsules minute, sub- 

 globose ; seeds very small, black. — A plant doubtfully referred to this Old 

 World species by Dr. Britton, was found in Sierra Valley by Mr. Lemmon. 



7. T. marina, Britt. 1. c. 126. Arenaria rubra, var. marina, Linn. Sp. 

 PI. i. 423 (1753). Spergula marina of pre-Linna?an authors. Lepigouum 

 marinum, Wahlb. Root thickish, not much branched, perhaps sometimes 

 perennial: stems ascending, 3 — 8 in. high, somewhat compressed or angu- 

 lar, glabrous or somewhat glandular-pubescent : leaves semiterete, nar- 

 rowly linear, acute, light green, glabrate, seldom exceeding the inter- 

 nodes ; stipules broadly ovate, abruptly acuminate : cymes scarcely leafj' ; 

 pedicels about twice as long as the capsules : sepals acute or acuminate, 

 with a broad or narrow scarious margin : petals broadly ovate, obttise, 

 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 ; perhaps also on subsaline 

 plains of the interior. 



8. T. salina, Britt. 1. c. 127 ; Presl. Fl. Cech. 93 (1819), under Spergu- 

 laria. 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, seldom longer than the inter- 

 nodes ; stipules broadly ovate, short-acuminate, not shining : pedicels
