the sepals. — Little, matted herbs, with thread-like or awl-shaped leaves, no 

 stipules, and small flowers terminating the stems or hrantlies ; in summer. 

 (Name from saijina, fattening; previously applied to the spurrv.) 



« Parts of the Jhwer in fours, rarely with some few in fives. 



1. S. prociimbens, L. Annual or perennial, J^/^ressec/ or. s;jrfio(//n</ on 

 the ground, glal)rous; leaves linear-thread-shaped ; ajxr of the pidnncle often 

 hooked soon after flowering; petals shorter than the broadly ovate obtuse sepals, 

 sometimes none. — Springy jilaces and damj> roiks, coast of Maine to I'enn. 

 (Ku.) 



2. S. apetala, L. Annual, erect or ascending; leaves ciliate at base or 

 glabrous; jutals none or very small; ]>eilundes altvai/s erect. — Dry soil, Mass. 

 to Peuu. ; scarce, seemingly native '. (Eu.) 



* * Parts of the flower in fives, the stamens not rarely 10. 



3. S. decumbens, Torr. & Gray. Annual, ascending ; the peduncles and 

 calyx with the margins of the upper leaves atfrst glandnlar-pnbesrent ; leaves 

 short, often bristly -tipped, not fascicled in the axils ; peduncles slender ; petals 

 equalling or shorter than the cali/x ; pod oblong-ovate, nearly twice longer than 

 the acutish sepals. (S. subulata, Man., not Wi)iim.) — E. Mass., to 111., Mo., 

 and southward. — ^'ar. S.Mf run, a slender form, apctalons, at least in the later 

 flowers. — Near riiiladelpliia, in waste ground, and in sandy fields at Somers' 

 Point, N. J., C. E. Smith. Seeds minutely roughened. 



4. S. noddsa, Fenzl. Perennial, tufted, glabrous, or glandular above; 

 stems ascending (3-5' high) ; lower leaves thread-form, the upper short anti 

 awl-shaped, with minute ones fascicled in their axils so that the branchlets ap- 

 pear knotty, petals much longer than the calyx. — "Wet .sandy soil, along the 

 coast of ]Maine and N. H., also Lake Superior, and northward. (Eu.) 



11. BUD A, Adans. Sand-Spurrey. 



Sepals 5. Petals 5, entire. Stamens 2-10. Styles and valves of the many- 

 seeded pod 3, very rarely 5, when the valves alternate with the sepals ! Em- 

 bryo not coiled into a complete ring. — Low herbs, mostly on or near the sea- 

 coast, with filiform or linear somewhat fleshy oi)posite leaves, and smaller ones 

 often clustered in the axils ; stipules scaly-mem branaceous ; flowering all sum- 

 mer. (Named probably for the city so called.) — Genus also known as Tissa, 

 Adims., Spergularia, Presl, and Lepigonum, Wahlb. The species are very 

 variously understood by European botanists, and are much confused, as well 

 as the synonymy. Our forms are annual, or at the most biennial. 



1. B. rubra, Dumort. Nearly glabrous, the summit of the prostrate or 

 ascending slender stems, peduncles, and sejjals usually glandular-pubescent ; 

 leaves linear, flat, scarcely fleshy ; stipules lanceolate, entire or cleft ; pedicels 

 longer than the bracts; pods and pink-red corolla snuill (1^"), hardly equal- 

 ling or exceeding the calyx ; seeds rough with projecting ]ioinls, semi-obovate or 

 gibbous-wedge-shaped, wingless. (Spergularia rubra, Presl.) — Dry sandy soil, 

 New Eng. to Va., along and near the coast, but rarely maritime. (Eu.) 



2. B. marina, Dumort. More decidedly fleshy than the preceding, erect 

 or ascending, usually pubescent, with ovate stipules, terete leaves, and jjcdi- 

 tels 2 - 4" long ; sepals usually becoming 2 - 2^" long, little shorter than the
