Description
|
Erect, branching, sparingly pubescent herbs; branches slender; roots fibrous. Leaves alternate but sometimes appearing opposite, simple, ovate, the margins serrate, chartaceous, sparingly pubescent; petioles slender. Inflorescences several, loose, small, umbellate or cymose panicles subtended by foliaceous bracts; pedicels slender, subtended by minute linear bracteoles. Heads small with few florets, discoid; involucral bracts 3-5, ovate-lanceolate, unequal, pubescent, drying reddish brown; receptacle minute; paleas indurate, acute, longer than the involucral bracts, pubescent, enveloping the florets; disc florets 3-5, the corolla narrowly campanulate, pubescent outside, the anthers black with narrowly deltoid append- ages, basal auricles present but obscured, the style branches deltoid with a cuspidate apex, pubescent, the style base expanded, slightly immersed in the nectary, the ovary compressed. Achene plump, pubescent without longitudinal veins; pappus a ring of minute, partially connate scales.

Note
|
This genus is superficially similar to Stevia in its reduced heads, but the florets, individually wrapped in paleas, and the pappus of minute scales easily separate the two genera, which are in fact, only distantly related. Superficially the plants are similar to those of Eleutheranthera ruderalis but the flower structure and achene is quite different, and the pubescence is sparser.
