Type
Zeevlewya gracilis
Diagnosis
Flowers monoclinous, epigynous, slightly zygomorphous, shortly pedicellate or sessile with a swollen abscission scar, tubular, slightly curved, about 7 mm long. Floral buds clavate to obovate, obtuse, basally stalklike, conspicuously expanded in the upper third where the calyx lobes are separated. Hypanthium straight or slightly curved, longitudinally ridged and minutely hairy (with pits of hair bases on impression) over the ovary, narrowly cupuliform or funnel-shaped with 0–6 calyx lobes above. Calyx lobes narrow lanceolate, acuminate, glabrous, one lobe considerably longer than the others, valvate and clasping the stamens in bud, narrowly spreading, deciduous or obliterated later in development. Petals apparently lacking. Androecium of 0–6 stamens with long slender flexible filaments proximally adnate to the calyx tube, unequally exserted. Anthers introrse, elliptical to cordiform, dehiscing into two valves. Filament persistent after shedding the anthers as hooked bristles converging over the tube. Basal hypanthium strongly elongated in fruiting, spindle-shaped, constricted below the shrinking upper hypanthium.
