Gnetum gracilipes C. Y. Cheng,植物分类学报13 (4) : 88. 图64 . 1-3. 1975.

Vines; old branches usually gray. Petiole slender, ca. 1 cm; leaf blade narrowly oblong or narrowly elliptic, sometimes elliptic, 6-15 × 2-5.5 cm, leathery or nearly so, base cuneate or sometimes rounded, apex shortly acuminate or acute. 

Male inflorescences once branched, occasionally twice; male spikes with 12-16 involucral collars, each collar with 50-60 flowers plus 10-14 sterile female flowers, basal hairs forming a dense cushion. 

Female inflorescences axillary, unbranched, short and thick when ripe; female spikes with involucral collars 6-10 mm apart. Seeds broadly ellipsoid or oblong-ellipsoid, 2.5(-3) × 1.5-1.6 cm, base cuneate into a stipe, apex acute or subacute, outer coat thin and smooth; stipe 1.5-2.5 cm × ca. 2 mm, with inconspicuous, longitudinal grooves.

Shows many similarities to the rather poorly known Gnetum latifolium Blume var. longipes (Markgraf) Hiep, from Cambodia, New Guinea, the Philippines, and probably Vietnam, and may indeed prove to be the same taxon. The information available suggests that there is a discontinuity between G. latifolium var. longipes and other varieties of G. latifolium, and so the Chinese taxon is here treated as a distinct species.<ref>[http://www.iplant.cn/info/Gnetum%20gracilipes?t=foc 细柄买麻藤 Gnetum gracilipes] 产地: 广西十万大山(模式标本地); 分类树 盖子植物纲 Gnetopsida 买麻藤目 Gnetales 买麻藤科 Gnetaceae 买麻藤属 Gnetum 细柄买麻藤 Gnetum gracilipesi... </ref>

==辨析==
本种与[[菲律宾]]产的G. arboreum Foxw. 相似，不同之处在于本种之叶的先端短渐尖或急尖，成熟种子宽椭圆形或矩圆状椭圆形，两端窄尖形如橄榄。而后者之叶的先端长渐尖，尖头钝，成熟种子两端不窄尖。与国产的其它有种子柄的种类相比，本种具细而长的种子柄，种子两端窄尖极易区别。
