Description
The genus Dyscritothamnus, comprising only two species, is distinguished by this combination of features:[4]
- They are woody shrubs with leaves appearing singly at each point along the stems, not opposite one another.
- Flowering heads consist of reduced flowers (florets) with orange corollas
- Two series of bracts of conspicuously different lengths form a cylindrical structure, the involucre, from which the florets arise in two series.
- Atop the one-seeded, cypsela-type fruits the pappuses consist of numerous bristles with tiny projections along their sides, like barbs along a very slender feather's rachis.
