Shrubs, unarmed, terrestrial, without raphides in the tissues, with ample resinous exudate on leaves and flowers, with branching perhaps sylleptic, principal stems with numerous short internodes. Leaves opposite, subsessile to shortly petiolate, entire, with the higher-order venation not lineolate, without domatia; stipules shortly fused around stem, tubular, truncate, erect, smooth, arrangement in bud unknown, persistent after the leaves fall. Inflorescences axillary at stem apex, with flowers solitary, ebracteate. Flowers subsessile, whether bisexual, protandrous, or homostylous unknown, presumably diurnal; hypanthium obconic, 4-ridged or -winged; calyx limb well developed, deeply 4-lobed, red, perhaps the entire calyx functioning as a calycophyll; corolla tubular, yellow, medium-sized (ca. 2 cm long), internally glabrous, lobes 4, perhaps ligulate, in bud imbricated, apparently without appendage; stamens 4, inserted in upper part of corolla tube, anthers narrowly oblong, dorsfiixed near base, dehiscent by linear slits, partially exserted, whether appendage present unknown; ovary 2-locular, with ovules 1 in each locule, basal, stigmas 2, shape unknown, exserted. Fruit samaroid, obconic, indehiscent, rather small (ca. 3.5 mm long), perhaps cartilaginous, 4-winged, with calyx limb persistent and perhaps enlarging (12--17 mm long); seeds one per locule, obovoid, punctate-reticulate.
