252 CARYOPHYLLACE^. Spergularia. 



summit, 2 to 2| lines long : flowers axillary in dichotomous racemes : petals pink : capsule 

 equalling or a tliird to half longer than the calyx ; seeds minute, turgid, obovate, usually 

 roughened, less frequently almost or quite smooth (Buda marina, var. leiosperma, N. E. Brown,

 (not Britton), Fl. Francis. 128, iacl. var. sordida, a form with copious glandular pubescence 

 and dense secund racemes, and var. Sanfordi, scarcely viscid and looser flowered. T. sparsi- 

 Jiora, Greene, Erythea, iii. 47, a form with more elongated leafy-bracted inflorescence, yet 

 freely passing to the usual form. — Common on both the Atlantic and Pacific coasts, also 

 occurring upon the Gulf coast, and not infrequent about salt lakes and in alkaline regions of 

 the interior, especially westward. 



Var. C?) minor, Robinson, 1. c. Smaller, 2 to 3 inches high: flowers smaller and 

 very numerous, on short pedicels (| to 2 lines in length) and consequently rather densely 

 aggregated. — Buda marina, var. ? minor, Wats. & Coulter in Gray, Man. ed. 6, 90. — Coast 

 of New Hampshire and Massachusetts. An ambiguous form suggesting the western S. 

 tenuis, but smaller and with a better developed corolla. 

 S. borealis, Robinson, 1. c. More slender and in well developed specimens more diffusely 

 branched than the last preceding species, 2 to 5 inches high, usually glabrous : leaves 

 seldom fascicled; stipules ovate, broader than long, obtuse or obtusish : sepals ovate, 1 to 1^ 

 lines long, very obtuse : petals white or roseate : capsule ovate-oblong, usually almost or 

 quite twice as long as the calyx ; seeds generally wingless and nearly or quite smooth, a half 

 line in diameter, about twice as large as in iS. salina. — Arenaria rubra, $, Michx. Fl. i. 274. 

 (Dr. Britton, who has examined the type of Michaux's variety, pronounces it identical with 

 this species.) A. Canadensis, Pers. Syn. i. 504, the oldest specific name, but not to be selected 

 for use under Spergularia, since S. Canadensis has been employed by Don, Syst. i. 426, for 

 a " pilose " and " rather hispid " plant, extending from " Canada to Carolina " and being 

 doubtless S. salina, Presl. Lepigonum medium, Wats. Bibl. Index, 103, in part. Tissa salina,

* * * * Stout and fleshy perennials : flowers large. 



S. media, Presl. Root stout, perpendicular, giving off numerous accessory fibres : stems 

 fleshy, decumbent, ascending : pedicels commonly exceeding the flowers, deflexed ; racemes 

 short-bracted, secund : petals rose-lilac : sepals rather broadly ovate-oblong, obtusish, about 

 two thirds the length of the capsules ; the latter ovoid, l)ecoming 3^ lines long ; seeds often 

 broadly winged. — Fl. Sic. p. xvii. & in Griseb. Spicil. Fl. Rumel. i. 213. iS\ marginata,

 Frji (herb. N. Y. Bot. Garden), and Saucelito, Marin Co., Calif., Mrs. Brandegee (herb. 

 Calif. Acad. Sci.). A species now generally recognized under some name by European 

 authors. Although difficult of technical limitation on the side of S. salina, it can in general 

 be readily distinguished by its stouter- root and much larger flowers and seeds. From tlie 

 following it differs in its relatively broader sepals and well exserted capsule. 



S. macrotheca, Heynh. Smooth to densely glandular-tomentose : root large: stems 

 spreading, ascending, 8 to 15 inches in height: leaves linear, acute, mucronate, 8 lines to 2 

 inches in length, about a line in breadth ; internodes more or less developed, usually 6 lines 

 to 1 inch long : floral bracts resembling the leaves : inflorescence inclined to be racemiform ; 

 pedicels 4 to 12 lines in length, spreading or more or less deflexed : sepals lanceolate, acutish 

 or subacuminate to an obtuse point, thick in the middle, nearly smooth or viscid-glandular, 

 conspicuou.sly membranous-margined : petals roseate, shorter than the sepals : capsule ob- 

 long-ovoid, acuti.^1, about equalling the calyx. — Nomencl. ii. &B9,Jide Hook. f. & JacLson,
