Description
The genus Dyscritothamnus, comprising only two species, is distinguished by this combination of features:
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.
List of species As of 2025, these species are recognized:
Dyscritothamnus filifolius B.L.Rob. - Guanajuato, Hidalgo Dyscritothamnus mirandae Paray - Querétaro
