10. 滇蜡瓣花
Corylopsis yunnanensis Diels in Not. Bot. Gard. Edinb. 5: 226, 1912.
落叶灌木，高达3米；嫩枝有绒毛，干后带灰色，老枝暗褐色，无毛，有皮孔；芽体矩圆形，外侧无毛。叶倒卵圆形，长5-8厘米，宽3-6厘米，先端圆形，有1个三角状小尖头，基部不等侧心形；上面暗绿色，初时有柔毛，老叶变秃净；下面灰色，有星毛，或仅背脉上有长毛；侧脉约8对，第一对侧脉很靠近基部，第二次分支侧脉不强烈，在上面显著下陷，在下面突起，侧脉之间的平行小脉亦明显下陷；边缘有锯齿，齿尖稍突出；叶柄长约1厘米，有毛；托叶矩圆形，外面无毛。总状花序长1.5-2.5厘米，花序轴有黄褐色长绒毛，花序柄长不到1厘米，被褐色绒毛，基部有叶片2片；总苞状鳞片卵圆形，长1 -1.8厘米，外面无毛；苞片1个，卵圆形，长6毫米，有毛；小苞片2个，披针形，长3-4毫米，有毛；萼筒有星毛，萼齿三角卵形，有绒毛，先端略尖；花瓣匙形，长6-7毫米，宽5毫米；雄蕊长4-5毫米；退化雄蕊2裂；先端平截或钝，比萼齿为短；子房有星毛，花柱长2-2.5毫米，基部有毛。果序长3.5-4.5厘米，有蒴果14-20个；果序柄及果序轴均有绒毛；蒴果长6-7毫米，有星毛，宿存花柱稍弯曲，长2毫米。种子长4-5毫米，褐色。
分布于云南的西部。
叶和花的各种特征都接近蜡瓣花 C. sinensis, 但后者的总苞有柔毛，花柱突出花冠之外，退化雄蕊先端尖，萼齿无毛。它和短柱蜡瓣花 C. brevistyla的分布区几乎相同，后者嫩枝和叶无毛，托叶较狭窄，子房与萼筒分离，无毛，苞片亦较小。

Shrubs, to 3 m tall; young branches drying grayish, tomentose, older growth dark brown, glabrescent, lenticellate; buds oblong, glabrous. Stipules oblong, glabrous; petiole 10–12 mm, pubescent; leaf blade obovate-rounded, 5–8 × 3–6 cm, abaxially gray, stellately pubescent at least along veins, adaxially drying dark green, glabrescent, base asymmetrical, cordate, margin serrate, teeth short mucronate, apex rounded with a deltoid mucro; lateral veins 8 on each side, the 2 lowermost with obscure tertiary veins.
