Genus

Characteristics

Herbs or shrubs, the indumentum of stellate and often also simple hairs. Leaves petiolate (at least the lower ones), the stipules caducous, the blade cordate, the margins usually dentate, sometimes inconspicuously so. Flowers axillary and solitary, or in paniculiform, or spiciform inflorescences; epicalyx wanting; calyx 5-merous, campanulate or somewhat turbinate, lobed to about the middle, per-sistent; corolla small or medium-sized, the petals 5, the base adnate to the staminal tube; staminal tube short, ventricose, filamentiferous at the apex, the filaments numerous, the anthers reniform; ovary of 5-11 carpels, each carpel 3-ovulate, the ovules anatropous, pendulous; styles isomerous with the carpels, the stigmas capi-tate. Fruits stellate-turbinate or shortly cylindric, of 5-11 mericarps, these usually apiculate to rostrate apically, more or less divided into 2 superposed cavities by a transversal, membranous, tongue-like projection of the dorsal wall (endoglossum), the lower cavity with 1 seed, the upper with 2 collateral or superposed seeds, ulti-mately incompletely 2-valvate; seeds subglobose-reniform, glabrous or pubescent; embryo curved, the albumen scant.
More
Subshrubs or shrubs. Stems erect or rarely decumbent, setose or stellate-hairy, not viscid. Leaves: stipules persistent, linear to lanceolate; blade ovate to broadly ovate, unlobed or sometimes shallowly 3-lobed, not dissected, base cordate, margins crenate to serrate. Inflorescences axillary umbels or solitary flowers, sometimes aggregated in terminal inflorescences; involucel absent. Flowers: calyx accrescent, subequal to mature fruit, not inflated, lobes unribbed, triangular to ovate, basally rounded; corolla rotate or shallowly campanulate, yellow; staminal column included; ovary 5–8[–10]-carpellate; ovules (2 or)3 per cell; styles 5–8[–10]-branched; stigmas capitate. Fruits schizocarps, erect to weakly ascending, not inflated, oblate, slightly indurate, hairy; mericarps 5–8[–10], 1-celled sometimes with endoglossum which partially divides chamber into upper and lower portions (this may be interpreted as 2 cells), apex rounded, with divergent apical distal spines, lateral walls usually disintegrating at maturity, dehiscent. Seeds (2 or)3 per mericarp, turbinate, papillate, glabrous. x = 8.
