Chavica officinarum Miquel; Piper chaba Hunter; P. officinarum (Miquel) C. de Candolle.

Climbers glabrous except for rachis and stigmas, dioecious. Stems brownish when dry, ca. 2 mm thick, terete, striated. Petiole 5-11 mm, sheathed at base only; leaf blade narrowly elliptic, ovate-oblong, or elliptic, 8.5-16 × 3.2-7.5 cm, papery, glaucous when dry, densely glandular, base with both sides rounded or 1 side slightly tapered and short, tapered and short side sometimes concave to semicordate, ± symmetric to oblique, bilateral difference 0-5 mm, apex shortly acuminate to acute; veins 9-11, rarely more, pinnate, usually 4 or 5 on each side of midvein.

Spikes leaf-opposed. Male spikes 5-6.5 cm; peduncle slightly longer than petioles; bracts orbicular, 1-1.2 mm wide, peltate, sessile. Stamens 2 or 3; filaments nearly absent; anthers broadly ellipsoid. Female spikes 3-4 cm × ca. 7 mm; peduncle and bracts as in male spikes. Ovary immersed in rachis; stigmas 3, ovate-acute, recurved. Unripe drupe partly connate to rachis, apex rounded. Fl. May-Jul.

?Yunnan; cultivated in Guangdong [India, Indonesia (?Timor), Malaysia, Philippines, Thailand, Vietnam]

Widely cultivated and of uncertain origin. There is a single record of this species (or a closely related one), apparently growing wild in Yunnan. The collection, C. W. Wang 75415, differs from the usual cultivated plant by the longer infructescence.

假荜拔分布范围

中国仅见于广东广州)有栽培。印度泰国越南马来西亚印度尼西亚菲律宾也有,上述这些国家有的亦为栽培,原产地可能是帝汶岛[3]

假荜拔主要价值

果序药用,可作兴奋剂,亦为胃寒要药。[4]
