3-6 lines long, pungent flowers 5-merous on long pedicels that are erect in 
fruit: sepals a line long: petals nearly as long: stamens 10: capsule ex-

obtuse, exceeding the petals: stamens 1¢: capsule xt length nearly twice 
longer than the calyx. In wet places on high mountains, Arctic America 
to California. 
A. erassicaulis Greene l. c. Sagina crassicaulis Watson. Smooth per- 
ennial stems several to many, branching 1-5 inches long: leaves linear, pun- 
gent thickish, 2-7 lines long or more, the basal forming a rosette which 
may persist or not; the cauline connate by broad scarious membranes: pedi- 
cels numerous, straight: flowers 5-parted, petals and sepals subequal 1144 
lines long: capsule 44-44 longer. Near the sea, mouth of the Columbia river

9 SPERGULA L. Gen. n. 586. 
Dichotomously or fasciculately branched annuals with subu- 
late fascicled or apparently whorled leaves with small scarious 
stipules and small white flowers on slender pedicels in dichoto- 
mous cymes. Sepals 5, entire. Stamens 10, rarely 5. Ovary 1- 
celled, many-ovuled; styles 5, alternate with the sepals. Cap- 
sule 5-valved, the entire valves opposite to the sepals. Seeds 
laterally compressed, acutely margined or winged : embryo spiral. 
S. arvensis L. Sp. 440. Smooth: stems several, a foot or two high: 
leaves filiform, numerous in apparent whorls, 1-2 inches long; stipules 
small: pedicels at length reflexed: sepals oblong to ovate 2 or 3 lines long, 
equalling the petals, a little shorter than the broadly ovoid capsule: seeds 
rough, acutely margined. Sandy fields, especially near the Coast, Wash- 
ington to California; naturalized from Europe,

Low, more or less succulent herbs, usually depressed, with se-

5, rarely few or wanting. Stamens commonly 10. Styles 3, very 
rarely 5. Ovary 1-celled. Capsule with as many valves as styles, 
when 5, alternate with the sepals. Seeds often margined.

base, sparingly pubescent, at least above: leaves linear, fleshy, 1-2 inches 
long; with large ovate stipules: flowers large, subracemose; pedicels 4-12 
lines long becoming reflexed : sepals ovate-lanceolate, 3-5 nerved, more or less 
tomentose, 3 lines long or more, equalling or exceeding the petals: capsule
