Species

Angiosperms > Icacinales > Icacinaceae > Pyrenacantha

Characteristics

Climber; young branches twining, densely setose with retrorse bristles; bark grey rough. Leaves with very hairy petioles; lamina 5-10 x 2.5-6.5 cm, variable in shape, that of the leaves in the lower part of the branches clearly 3(5?)-lobed, that of the others ovate to narrowly ovate; apex obtuse to acute and mucronate, margin with prominent gland-like hairy teeth, base broadly cuneate, ± rounded or rarely cordate; the upper surface sparsely hispid with appressed hairs (the smaller ones hooked) pointing mainly to the margin, the lower densely hispid with simple ± patent straight hairs. Inflorescences supra-axillary to proportionately smaller leaves. Male spikes c. 5 cm long, on hairy peduncles c. 2.5 cm long; flowers numerous, rather loose, sessile, subtended by bracteoles. Female flowers in short, oblong or subcapitate pedunculate few-flowered spikes. Drupe c. 1.8 cm long, slightly compressed, hispid.
