The lamina is entire. The flowers are hermaphrodite, and usually showy, ranging in size from small to large, and composed of numerous distinct parts that change grade slightly as they spiral around the receptacle. The parts begin with a

The stem presents nodes unilacunar (with one trace), with internal phloem absent, secondary thickening developing from a conventional cambial ring, xylem with tracheids; The sieve-tube plastids are S-type. The fruit is non-fleshy; the fruiting carpel is dehiscent, with a follicle (the cycle of follicles often spreading radially in a stellate pattern) and presents only one seed. The seeds are copiously endospermic and oily. The embryo is well differentiated (very small), achlorophyllous. The germination is phanerocotylar.
