==毛九节形态特征==
灌木，高0.75-1.75米；小枝密被棕褐色卷曲长毛。叶对生，膜质或纸质，椭圆形、椭圆状倒卵形或长圆状倒披针形，有时稍弯，长8-17.5厘米，宽3-9.5厘米，顶端短渐尖或短尖；

基部钝圆、短尖或楔形，边全缘，具缘毛，干时暗红褐色，两面被紧贴的长毛，在中脉较密，中脉在上面平或微凹，在下面凸起，侧脉8-15对，与中脉成45度角开出，在上面平，在下面凸起；

叶柄长1-5厘米，密被棕褐色卷曲长毛，毛常渐脱落；托叶膜质，脱落，卵状三角形，顶端2裂，渐尖，外面密被棕褐色卷曲长毛，长达2厘米。 

聚伞花序顶生或腋生，长6-8厘米，宽5-6厘米，总花梗和分枝密被棕褐色卷曲长毛，总花梗长3.5-6.5厘米；苞片线状披针形，渐尖，长达1厘米，被疏缘毛。

果红色，长圆状椭圆形，无毛，长0.8-1厘米，直径4-5毫米，有纵棱，顶冠以宿萼片，宿萼片外面被长毛；种子2，黑色，腹面稍凹下，长5-6毫米。果期8-12月。

Shrubs, 0.75-1.75 m tall; stems densely villous to villosulous. Petiole 1-5 cm, densely villous; leaf blade drying papery or membranous, dark reddish brown, elliptic, elliptic-obovate, or elliptic-oblong, 8-23 × 3-11 cm, moderately to densely and similarly strigose to hirsute on both surfaces, base acute or obtuse to rounded, margins flat and ciliate, apex acute to shortly acuminate with tip to 1 cm and sometimes curved; secondary veins 5-15 pairs, not forming a submarginal vein, apparently without domatia; stipules caducous to tardily deciduous, ovate-triangular, interpetiolar, 15-25 mm, densely hirsute to villosulous, 2-lobed for ca. 1/2, lobes narrowly triangular, acuminate to caudate. 

Inflorescences terminal becoming pseudoaxillary, congested-cymose to subcapitate, densely hirsute or villous, pedunculate; peduncle 3-6.5 cm; branched portion pyramidal to subglobose, 2-3.5 × 2-5 cm; bracts linear-lanceolate, 4-10 mm, ciliate, acuminate. Flowers subsessile. Calyx glabrescent to sparsely villosulous; hypanthium portion obconic, ca. 1 mm; limb 2.5-3.5 mm, lobed for ca. 2/3; lobes narrowly triangular to linear-lanceolate. Corolla in bud funnelform, outside villosulous, to 4 mm. Drupes red, oblong-ellipsoid, 8-10 × 4-5 mm, sparsely villosulous to glabrescent; pyrenes 3- or 4-ribbed. Fl. Jul, fr. Aug-Dec.

The protologue described the inflorescences as sometimes axillary, but this appears to be a description of the position separated here as pseudoaxillary. W. C. Chen (in FRPS 71(2): 59. 1999) described the petioles as becoming glabrescent with age and the secondary leaf veins as impressed above, but these conditions have not been seen on any of the specimens studied.The protologue described the inflorescences as sometimes axillary, but this appears to be a description of the position separated here as pseudoaxillary.
