blunt, entire, or occasionally toothed, from 8 to 9 inches
long, and about 3 inches broad ; narrowed towards the base,
furnished with a stout midrib, which becomes so attenuated,
near the top, as to be scarcely distinguishable; those o f the
stem furnished with a few large coarse teeth; lower ones
spathulate, resembling the radical ones ; upper ones clasping
the stem, ovate-oblong, slightly conduplicate, from 2 to 4
inches long, and furnished with 5 nerves. Panicle corymbose,
large, and spreading. Capitula about, the size of those
of Stevia purpurea. Peduncles angular, glabrous. Bractes
ligulate, obtuse, glabrous, adpressed, coriaceous, 3 lines
