Shrubs; taproot stout. Stems spreading, woody, hirsutulous; caudex absent; aerial flowering stems spreading, herbaceous, hirsutulous. Leaves usually persistent through anthesis, 1 per node, cauline, alternate; petiole present, blade narrow to broadly elliptic, margins entire. Inflorescences terminal, cymose; branches dichotomous, not brittle or disarticulating into segments, round, hirsutulous, each node with 1 short-pedicellate flower and 4-12 sessile or subsessile flowers; bracts 3-4 at proximal nodes and leaflike, 2-3 at distal nodes and scalelike, distinct, hirsutulous. Peduncles erect, slender. Involucral bracts obscure, in 2 whorls of 3 plus 2 lobes at proximal nodes, distinct, reduced to 2 lobes at distal nodes, not awn-tipped. Flowers 4-6 per involucral cluster, sessile or pedicellate; perianth yellow to reddish yellow, broadly campanulate when open, narrowly urceolate when closed, hispidulous abaxially; tepals 6, slightly dimorphic, those of outer whorl broader and longer than those of inner whorl, entire apically; stamens 9; filaments basally adnate, pilose basally; anthers yellow, oblong. Achenes, light reddish brown, not winged, 3-gonous, pubescent apically. Seeds: embryo curved. x = 20.
