 of the disc, incurved in bud, sometimes erect, the filaments often connate at base; ovary inferior, 1- to many-locular; ovules 

 many, on axile, rarely on parietal placentae; fruit loculicidally dehiscent or indehiscent; seeds nearly destitute of endosperm;

 ninerved; stipules absent; flowers bisexual, usually showy, actinomorphic; calyx short-tubular, adnate to the ovary or sometimes 

 connected by the septa, or free, the lobes imbricate or valvate in bud; petals imbricate, free; stamens as many or twice as many
