Smallii Britton, Mem. Torr. Club 4: 132. 1893. Similar to the preceding species but taller, grow- ing in large clumps; stem li°-2i° high, slender, densely and persistently floccose-woolly at the base and in the lower axils, or finally glabrate. Basal leaves elongated-oblong or linear-oblong, obtuse or acute, long-petioled, crenate-dentate, 3'-6' long, 3"-i2" wide, at first tomentose, at length nearly glabrous; stem leaves several, deeply pinnatifid, or the lower lyrate, the uppermost very small; heads very numerous, 4"-S" broad, about 2V high, slen- der-peduncled, forming large corymbs; rays 8-10; achenes hispidulous; pappus white. In meadows and thickets, southeastern Pennsylva- nia to Florida and Alabama. May-June. 22. Senecio densus Greene. Western Squaw- weed. Fig. 4631. Senecio aureus var. compactus A. Gray, Syn. Fl.

Basal leaves linear-cuneate, entire or 3-toothed at the apex, i'-3' long, 2"-$" wide, thick, slender-petioled, the petioles commonly woolly-mar- gined ; lower stem leaves often much larger and broader, usually laciniate or pinnatifid, but sometimes similar to the basal, the uppermost very small and sessile; heads several, 8"-io" broad, short-peduncled in a compact co- rymb; rays 10-15; achenes hispidulous; pappus white.
