EuPATORiuM. COMPOSITE. 85 



Alabama! and Western Louisiana! Aug.-Oct. — Stem 2-3 feet high. 

 Leaves spreading or divaricate, rather rigid, perhaps never verticillate, sel- 

 dom fascicled in llie axils, the uppermost rarely alternate, both surfaces of a 

 pale glaucous hue, the midrib prominent beneath ; the lower ones 2 or rarely 3 

 inches in length, and from one-fourth to nearly half an inch wide, serrate 

 wuh appressed teeth; the upper narrower and more finely serrate, or 

 sometimes entire. Corolla, &c. nearly as in E. hyssopifolium. Appendages 

 of the anthers short, obtuse. Branches of the style exserted.— This has 

 sometimes been confounded with P2. hyssopifolium, but is readily distin- 

 guished as well by the leaves as by the very scarious and acute scales of the 

 involucre. 



8. E. cuneifolium (Willd.) : pubescent; stem simple or branching, loosely 

 corymbose at the summit; leaves very short, ojiposite, or the uppermost 

 frequently alternate, obovate-oblong, s])atulate or oblong-lanceolate, acute or 

 attenuate at the base, slightly petioled, tripli-nerved or 3-nerved from the 

 base, pubescent and punctate on both surfaces, mostly obtuse, and with a 

 few obtuse serratures towards the apex; heads 5-flowered, somewhat crowd- 

 ed on the loose tomentose branchlets of the corymb ; scales of the involucre 

 8-10, very pubescent, sprinkled with glands, obtuse ; achenia slightly glan- 

 dular.— T'FzMfZ. / sjKC. 3. p. 1753, not of DC! E. glaucescens, EU.! sk.

Shady places, S. Carolina ! Georgia ! Alabama ! and Florida ! Aug.- 

 Sept. — Stem about 2 feet high, erect or ascending at the base. Leaves 

 about an inch long, of a pale glaucous hue on both sides, very obtuse, the 

 uppermost sometinies acute, entire and cuneiform at the base, usually with 

 2-4 obtuse teeth on each side towards the summit. Involucre, flowers, 

 pappus, &c. nearly as in E. hyssopifolium. 



9. E. jmrvifl or urn {E\l.) : minutely velvety-pubescent, branching ; leaves 

 opposite, or the lower sometimes ternate, and the upper frequently alternate 

 (sometimes verticillate, opposite, and alternate on the same specimen), lan- 

 ceolate or oblong, minutely jmnctate, tripli-nerved, somewhat reticulate- 

 veined, unequally and acutely serrate, usually entire below the middle, 

 tapering to the base, the lower slightly petioled ; corymbs numerous ; heads 

 (small) crowded, 5-flowered ; scales of the involucre 8-10, in a double 

 series, pubescent and glandular; the exterior very short ; the interior linear, 

 obtuse ; achenia glabrous or minutely glandular. — Ell. ! sk. 2. p. 299, (not

/?. lancifolium : stem or branches strict, glabrous below, corymbose at the 

 summit; leaves opposite (sometimes ternate), lanceolate, rather rigid, almost 

 glabrous, acute, serrulate above the middle, tripli-nerved or 3-nerved ; the 

 nerves sparingly anastomozing. 



Damp soil, Virginia! to Georgia! Florida! Alabama! and Western Lou- 

 isiana! /). Ijoimmna, Dr. Leavenwor ill ! Louisiana and Texas, Dnimmond ! 

 Aug.-Oct. — Stem 2-3 feet high, usually diffusely branched above. Leaves 

 pale, minutely velvety-pubescent beneath, 2-3 inches long, often an inch 

 wide, varying from scarcely acute to acuminate, sometimes serrate nearly to 

 the base ; the texture rather firm. Heads about as large as in E. coronopi- 

 folium, crowded. Involucre shorter than the flowers.— In our var. jS. the 

 leaves arc smaller, nearly glabrous, and rather narrowly lanceolate, resem- 

 bling the upper leaves of E. parviflorum, witli which it agrees in other re- 

 spects. We had considered it a new species, but having observed various 

 intermediate states, we are satisfied that it is a mere variety of E. parvi- 

 florum. The E. ambiguum of Hooker is said to have 8-10-flowered involu-
