科属（Family & Genus）：紫金牛科（Myrsinaceae）密花树属
形态特征（Description）：大灌木或小乔木，高2-7米，可达12米；小枝无毛，具皱纹，有时有皮孔。叶片革质，长圆状倒披针形至倒披针形，顶端急尖或钝，稀突然渐尖，基部楔形，多少下延，长7-17厘米，宽1.3-6厘米，全缘，两面无毛，叶面中脉下凹，侧脉不甚明显，背面中脉隆起，侧脉很多，不明显；叶柄长约1厘米或较长。伞形花序或花簇生，着生于具覆瓦状排列的苞片的小短枝上，小短枝腋生或生于无叶老枝叶痕上，有花3-10朵；苞片广卵形，具疏缘毛；花梗长2-3毫米或略长，无毛，粗壮；花长 (2-) 3-4毫米，花萼仅基部连合，萼片卵形，顶端钝或广急尖，稀圆形，长约1毫米，具缘毛，有时具腺点；花瓣白色或淡绿色，有时为紫红色，基部连合达全长的1/4，花时反卷，长 (2-) 3-4毫米，卵形或椭圆形，顶端急尖或钝，具腺点，外面无毛，里面和边缘密被乳头状突起，中部以下无上述突起；雄蕊在雌花中退化，在雄花中着生于花冠中部，花丝极短，花药卵形，略小于花瓣，无腺点，顶端常具乳头状突起；雌蕊与花瓣等长或超过花瓣，子房卵形或椭圆形，无毛，花柱极短，柱头伸长，顶端扁平，基部圆柱形，长约为子房的2倍。果球形或近卵形，直径4-5毫米，灰绿色或紫黑色，有时具纵行腺条纹或纵肋，冠以宿存花柱基部，果梗有时长达7毫米。花期4-5月，果期10-12月。
分布（Distribution）：产我国西南各省至台湾，生于海拔650-2400米的混交林中或苔藓林中，也见于林缘、路旁等灌木丛中。缅甸，越南，日本也有。
用途（Use）：用根煎水服，可治膀胱结石；树皮含鞣质20.11％；叶可敷外伤；木材坚硬，可作车杆车轴，又是较好的薪炭柴。
