Stem finely speckled with purple, green or more often suffused with 
purple, not glaucous, scarcely darker at the nodes, usually solid but 
frequently hollow, scabrous-puberulent above and apparently some- 
what glandular: leaves generally in 3's or 4's occasionally in 2's or 
5's, from broadly to narrowly ovate, sub-acuminate, abruptly nar- 
rowed to a conspicuous petiole which is 10-15 mm. long, coarsely 
serrate with somewhat rounded and mucronate or sharper teeth, 
veiny and often rugose, more or less plainly 3-nerved, above usually 
scabrous, beneath atomiferous and glabrous except on the veins 
which are more or less scabrous-puberulent: inflorescence rather 
small and dense, convex, when well developed hemispherical or short- 
oblong: heads narrowly oblong, 6-9 (rarely 5 or 12)-flowered, usually 
deep-purple: involucral bracts slightly narrower than in the next 
species; the inner often sub-acute: corolla 4.5-5.5 mm. long, slightly 
exserted: achenes 3.5-4.5 mm. long.—Borders of swamps and in
