from all other genera of the order by the absence of a corolla. Calyx 

 purplish or white, campanulate, 5-lobed, assuming the appearance of 

 a corolla, the stamens alternating with its lobes. Capsule 6-valved ;it 

 apex. Seeds few, immersed in the tissue of the placenta. (From 

 the Greek glaukos, sea-green.) 



1. G. maritima L. Sea. Milkwort. Herbage somewhat succu- 

 lent; running rootstocks slender; stems 8 to 11 in. high, erect, or 

 ascending from a decumbent base, simple or eventually branching; 

 leaves oblong, 4 to 7 lines long; flowers less than 2 lines long, solitary in 

 the axils, almost sessile; calyx-segments elliptic; capsule globose, a 

 little over 1 line long. 



Marshy shores of San Francisco and Suisun Bays. June. 



3. ANAGALLIS L. Pimpernkl. 



Low herbs with opposite or sometimes ternate entire leaves. Flow- 

 ers axillary, on slender pedicels. Calyx deeply 5-cleft into narrow 

 segments. Corolla rotate, deeply 5-parted, the rounded lobes con- 

 volute in the bud. Stamens 5, inserted on the base of the corolla; 

 filaments hirsute or pubescent. Capsule circumscissile. (Greek, 

 meaning delightful.) 



1. A. arvensis L. Poor Man's Weather-glass. Stems 1 ft. 

 long, procumbent or ascending; leaves deltoid-ovate, acute, sessile, 4 

 lines long, shorter than the pedicels; sepals lanceolate, acuminate, 

 scarious-margined toward the base, nearly distinct; corolla vermilion, 

 rotate, 4 to 5 lines broad, the petals lightly joined at base, minutely 

 glandular-ciliate at apex; capsules on recurved pedicels; seeds \ line 

 long, triangular, the surface pitted. 



Crescent City to Southern California, mostly near the coast: com- 

 mon about San Francisco Bay (Berkeley, Napa Valley, etc.). 

 Naturalized. 



4. TRI ENTALIS L. 



Low and glabrous perennials. Rootstocks sometimes stoloniferous, 

 tuberous. Stem simple, bearing scales or small leaves below and a 

 whorl of large leaves above, from the center of which the filiform 

 peduncles arise. Flowers commonly 7 (5 or 6)-merous. Corolla 

 rotate, deeply parted. Filaments long and filiform, united at base 

 into a very short ring. Style filiform. Capsule valves 5, revolute. 

 (Latin trientalis, containing one-third of a foot, in allusion to the 

 height of the plants.) 



1. T. Europaea L. var. latifolia Torr. Star-flower. Stems 4 

 to 6 in. high, from tubers £ to nearly 1 in. long; leaves of the inyolu- 

 cral whori 5 or 6, 1 to 2 in. long, broadly obovate, abruptly acute, 

 drawn down to a very short petiole; peduncle f to 2 in. long; corolla 

 white or rose-red, about 4 lines broad, its divisions abruptly acuminate
