落叶乔木或灌木，高可达14米；树皮薄，灰白色或茶褐色，无毛或稍被短硬毛。叶膜质，矩圆形，矩圆状披针形，稀卵形，长2-9(-11)厘米，宽1-4.4(-5)厘米，顶端渐尖，基部阔楔形，上面通常无毛或有时散生小柔毛，下面无毛或微被柔毛或沿中脉被短柔毛，有时脉腋间有丛毛，中脉在上面略下陷，在下面凸起，侧脉3-10对，顶端连结；叶柄短，长2-4毫米。花小，白色或玫瑰色，直径约1厘米，组成顶生圆锥花序，长5-15厘米，具灰褐色微柔毛，花密生；花萼有棱10-12条，长3.5-4.5毫米，5裂，裂片三角形，直立，内面无毛；花瓣6，长2-6毫米，皱缩，有爪；雄蕊15-30，约5-6枚较长，12-14条较短，着生于萼片或花瓣上，花丝细长；子房无毛，5-6室。蒴果椭圆形，长6-8毫米，3-6瓣裂；种子有翅。花期6-8月，果期7-10月。
产台湾、广东、广西、湖南、湖北、江西、福建、浙江、江苏、安徽、四川及青海等省区；喜湿润肥沃的土壤，常生于林缘、溪边。日本琉球群岛也有分布。
材质坚密，可作家具、细工及建筑用，也可作轻便铁枕木；花供药用，有去毒消瘀之效。

Lagerstroemia subcostata Koehne
南紫薇 nan zi wei
Lagerstroemia subcostata var. hirtella Koehne; L. unguiculosa Koehne.
Trees or shrubs, to 14 m tall. Branchlets glabrous to gray puberulous or pubescent. Petiole 2-4 mm; leaf blade oblong, ovate-lanceolate, elliptic, obovate-elliptic, or infrequently obovate, 2-9(-11) × 1-5 cm, papery, abaxially glabrous or slightly pubescent, lateral veins 3-10 pairs, base broadly cuneate to subrounded, apex acuminate. Panicles pyramidal, 7-16(-30) cm, gray-brown pubescent, densely flowered. Floral tube 6-merous, 3.5-4.5 mm, with (10 or)12(or 14) dark veins or obscurely (10 or)12(or 14)-ribbed, glabrous to densely gray pubescent; sepals 1-2 mm, adaxially glabrous; annulus thin or apparently absent; epicalyx absent. Petals white, pink, or purple, broadly ovate with obtuse base, 7-10 mm including claw 3.5-6 mm, claw ca. as long as blade. Stamens 15-30, dimorphic. Ovary glabrous. Capsules globose to mostly oblong, 6-9(-11) mm, 3-6-valved. Seeds including wing ca. 4 mm. Fl. Jun-Aug, fr. Jul-Oct.
Forest margins, streamsides; low to medium elevations. Anhui, Fuian, Guangdong, Guangxi, Hunan, Hubei, Jiangsu, Jiangxi, Qinghai, Sichuan, Taiwan, Zhejiang [Japan, Philippines].
It is difficult to separate the following two species, Lagerstroemia glabra (including L. stenopetala) and L. caudata, from the widespread L. subcostata. Further knowledge about the degree of development of indumentum and variability of leaf shape and size is needed. More abundant gatherings may erase apparent differences between the species.
