Altingia yunnanensis Rehd. et Wils. in Pl. Wils. 1: 422, 1913; 张宏达, 中山大学学报, 1973, 第1期59页。Liquidambar altingiana Bl. Fl. Jav. 17, 8.
常绿乔木，高约15米；嫩枝略有短柔毛，以后变秃净，干后灰褐色，老枝有皮孔。叶革质、矩圆形，长6-15厘米，宽3.5-6.5厘米，先端急锐尖，基部楔形，或有时略钝；上面绿色，干后稍暗晦略有光泽，下面秃净无毛；侧脉6-9对，在上面稍突起，在下面显著地突起，网脉在上下两面均明显；边缘有明显锯齿，有时下半部近于全缘；叶柄长1-2厘米，无毛；托叶线形，早落。雄花头状花序椭圆形，长约1厘米，常排成圆锥花序，生于枝顶叶腋内，花苞4片，卵形，长1.5厘米，雄蕊多数，近于无柄。雌花头状花序单生或排成总状，每个头状花序有花16-24朵，萼齿鳞片状，花柱长4毫米，被褐色短柔毛，果序柄长3-4厘米，被毛。头状果序近于球形，宽1.5-2.5厘米；蒴果无宿存花柱，先端稍突出头状果序之外；果序柄长3-5厘米；种子细小，有棱。
分布于云南的东南部，常见于红河及南溪河流域。就叶形看来，它和蕈树 A. chinensis较近似，但后者叶倒卵矩圆形，质地稍厚。从目前资料判断，东经105°是两者的分界线。

云南蕈树 yun nan tan shu
Trees (3–)15–30 m tall; young branches slightly pubescent, glabrescent, older growth lenticellate. Stipules linear, 2–5 mm, caducous; petiole 1–2 cm, glabrous; leaf blade usually oblong, 6–15 × 3–7 cm, leathery, abaxially glabrous, base cuneate, sometimes subrounded, margin serrate, apex acute; lateral veins 6–9 on each side, prominent on both surfaces. Male inflorescences ellipsoid, ca. 1 cm, several arranged in panicle; bracts 4, ovate, ca. 15 mm. Female inflorescences usually in racemes, 16–24-flowered. Peduncle 3–4 cm in fruit, pubescent. Male flowers: stamens sessile. Female flowers: staminode teeth scalelike; styles 3–4 mm, brown-pubescent. Infructescences subglobose, 1.5–2.5 cm wide. Seeds angular. Fl. Mar–May, fr. May–Jul.
Forests; ca. 1000 m. SE Yunnan.
