Climbers herbaceous, 1-2 m long, glabrous or very finely powdery puberulent, dioecious. Stems 3-4 mm thick, finely ridged when dry, glabrous. Petiole 1-2.5 cm, glabrous to very finely pubescent; prophylls ca. 1/2 as long as petioles; leaf blade ovate, ovate-lanceolate, or elliptic, 6-16 × 3-8 cm, membranous to thinly papery, drying pale green abaxially, abaxially densely brownish red glandular especially along veins, very finely powdery pubescent along veins especially abaxially, glabrescent, base rounded, or shallowly cordate, occasionally broadly cuneate, often oblique, apex acuminate to long acuminate; veins 5-7, apical pair arising 0.5-5 cm above base, next pair sometimes also arising above base; reticulate veins conspicuous Spikes leaf-opposed.

59.球穗胡椒(拉汉种子植物名称)
Piper thomsonii (C. DC.) Hook. f. Fl. Brit. Ind. 5: 87. 1886.——Chavica thomsonii C. DC. in DC. Prodr. 16: 389. 1868.
草质攀援藤本,长1-2米许;枝干时具细纵纹,无毛。叶纸质,有细腺点,卵形、卵状披针形或椭圆形,长6.5-14厘米,宽4-8厘米,顶端渐尖至长渐尖,基部通常偏斜,钝圆或浅心形,两面沿脉上被极细的粉状短柔毛(放大镜下始见),背面尤著,老时脱落;叶脉7条,最上1对离基5-15毫米从中脉发出,基部常与中脉平行紧贴,其余2对均自基出;叶柄长1-2厘米,被极细的短柔毛;叶鞘长为叶柄的1/2或稍过之。花单性,雌雄异株,聚集成与叶对生的穗状花序。雄花序于花期比叶片短3倍,密花;花序轴被毛;苞片圆形,无毛,近无柄,盾状,直径约1毫米;雄蕊4枚。雌花序短,球状,长和宽近相等,直径约6毫米,总花梗短于叶柄,长4-5毫米,花序轴和苞片与雄花序的相同; 子房离生,柱头2。浆果球形,密集,干时变黑色,直径约2毫米。花期4-6月。
产于云南中南部至东南部(楚雄、景东至西畴)。生于山谷密林或疏林中,攀援于树上,海拔1300-1700米。印度东部也有。
Piper mullesua D. Don与本种的雌株极相似,主要不同点在于前者为木质藤本,叶基部短狭或楔形,两面沿脉上无毛,叶柄通常较短,花两性等而显然有别。
