灌木或小乔木，高1-4米；叶对生，膜质，长圆形至椭圆状倒卵形，长8-15厘米，宽3-6.5厘米，顶端渐尖，基部楔形，上面无毛，下面近无毛或沿中脉上和脉腋内被短柔毛；侧脉每边约7条，在叶片上面平坦，在下面凸起；叶柄长1-2厘米；托叶阔卵状三角形，长约3毫米，外面无毛，里面有白色长毛，顶端急尖。花序生于侧枝顶部，多花，长7-9厘米，直径7-15厘米；花具梗，梗长3-6毫米；萼管钟形，长约1毫米，萼檐扩大，在顶部不明显的4裂，裂片三角形；花冠白色，冠管长约15毫米或长些，外面无毛，里面基部被疏柔毛；花丝极短，花药突出，线形，长约4毫米，花开时部分旋扭；花柱长约35毫米，柱头棒形，全缘。果球形，直径约6毫米。花期3-4月。
产广东、香港、海南、广西、云南等省区。生于海拔200-1300米的灌木丛中。分布于越南。模式标本采自香港。
全株入药，有清热解毒、活血去瘀之效，又能治感冒发热、中暑、肝炎、跌打刀伤。本种的叶表面有固氮菌所形成的菌瘤，满布叶上呈点状，故民间称“满天星”。

Petiole 1-2 cm, glabrous; leaf blade drying membranous, elliptic-oblong to elliptic-oblanceolate, 8-15 × 3-6.5 cm, often with bacterial nodules, adaxially glabrous, abaxially glabrous, glabrescent, or pubescent along midrib, base cuneate to acute, apex acuminate to acute; secondary veins 6 or 7 pairs; stipules broadly ovate-triangular, 1-3 mm, glabrous, acute to shortly aristate. Inflorescences terminal on lateral branches, laxly corymbose, 7-9 × 7-15 cm, many flowered, glabrous; peduncle 1-2 cm; pedicels 3-6 mm. Flowers pedicellate. Calyx with hypanthium portion ellipsoid, ca. 1 mm, glabrous; limb 0.5-1.5 mm, glabrous, shallowly lobed. Corolla white, outside glabrous; tube 12-19 mm, inside pilose at throat; lobes narrowly triangular-oblong, 5-7 mm, acute to obtuse. Style ca. 35 mm. Drupes globose, 6-7 mm, pilosulous to glabrous, calyx limb persistent. Fl. Mar-Jul, fr. Jul-Nov.
