racemose

D. Ajàcis, L. Flowers more numerous and spicately racemose; pods pubescent.—Sparingly escaped from gardens in E. Atlantic States.

Embryo foliaceous, heart-shaped.—Flowers greenish-white, in long racemose panicles.

Stems gregarious, erect or ascending from a creeping or decumbent base, slightly viscid, and with the mostly racemose short branches striate with about 4 sharp wing-like angles decurrent from the leaves; these broader than in the last, and mostly oblong, usually with all the lower ones opposite; flowers more crowded; sepals scarcely equalling the very small subglobose brownish pod; otherwise nearly as n. 1.—Wet or boggy grounds, E. Mass. to Lakes Ontario and Huron, Ill., and southward.

Smooth, or scabrous-pubescent or below hirsute, slender, often branched, 2–5° high; leaves rather finely serrate, ovate to oblong-lanceolate, pointed; the upper small, oblong to narrowly lanceolate, often entire; heads loosely racemose; rays 1–5 or none; achenes pubescent.—Dry grounds, Va. and southward.

Stems 1° high; glabrous or nearly so; heads ½´ high, rather few, racemose or spicate; outer scales lax, foliaceous; rays purple; leaves linear, entire.—Mo. to Tex., thence to Car. and Ga. § 2.
