1. Alepidea amatymbica, Ecklon and Zeyher, Enum. PI. 339 (1835). 
A glabrous plant with a robust, erect, hollow, grooved, and leafy stem, 
3- 7 ft. high, racemosely or paniculately branching from below the middle ; 
branches occasionally short but more often long and slender, exceeding 
^ ft. in length, ascending— spreading, with the ultimate branchlets minutely 
scaberulous or smooth. Leaves more or less herbaceous, large, pale olive- 
green with very prominent venation on the lower surface ; margin finely 
or coarsely dentate, teeth triangular, acute, yV- i in. long : radical laxly 
spreading, petiolate ; petiole flattened and winged, 3-7 in. long, J in. 
broad, entire, widening towards the base and clasping the stem ; blade 
4- 5 in. long, 2 in. broad, oblong, rounded at both ends ; cauline leaves 
sessile or rarely subpetiolate, distant or imbricate, adpressed or spreading, 
oblong to oblong-cuneate or spathulate, the lower 4-12 in. long, 1-3|- in. 
broad, the upper decreasing in size, auriculate with coarser toothing. 
Elowers — heads numerous, compound — umbellately disposed, congested, 
or scattered, 7-10-flowered, ^-^ in. diameter. Involucre usually of 5 
spreading or incurved, acute or acuminate, entire, coriaceous, keeled and 
nerved segments, with smaller triangular teeth occasionally alternating, 
pale olive-green without, pale yellow within. Calyx-teeth obsolete, -i-th 
line long, deltoid. Styles variable in length, erect or reflexed. Fruit 
smooth or slightly muricate at the apex, ovoid or suborbicular. Carpo- 
phores occasionally persisting on the mature receptacle. Dietrich Syn.
