Leaf blade generally ovate to hastate or oblong, base cordate, truncate, or rounded, margins entire, apex mucronate; surfaces soft-pubescent or glabrous. Inflorescences axillary or terminal, racemes or racemose panicles; bracts minute (bracteoles). Flowers 3-ranked; sepals 6-9, ovate to elliptic or obovate, outer sepals glabrous or pilose to sparsely pilose abaxially, inner sepals glabrous; petals 6, free.
