Wikstroemia gracilis Hemsl. in Journ. Linn. Soc. Bot. 26: 397. 1894; Rehd. in Sarg. Pl. WAS. 2: 536. 1916.
灌木，高约1米；小枝纤弱，被长而平贴毛发状糙伏毛；腋芽球形，被白色绒毛。叶对生或近对生，膜质，具长约1毫米的短柄，椭圆形、卵圆形或长圆形，长1.5-5厘米，宽0.8-2.8厘米，先端钝，基部钝圆或宽楔形，两面均被极稀疏的糙伏毛，后渐变为无毛，上面绿色，下面灰绿色，侧脉明显，纤细，每边约5-6条。花序总状或由总状花序组成的小圆锥花序，花序梗短；花黄色，外面被平贴毛，顶端4裂，裂片椭圆形，具明显的网纹；雄蕊8，2列；子房具柄，仅在顶端被柔毛，花柱短，柱头头状；花盘鳞片2枚，线形，1窄1宽。花期秋季。
见于四川、湖北海拔1100米的山坡林阴下。模式标本采自湖北兴山。

Wikstroemia gracilis Hemsley
纤细荛花 xian xi rao hua
Daphne rehderi Halda, nom. illeg. superfl.
Shrubs to 1 m tall. Branches very slender, turning brownish striate, long strigose; leaf buds ovoid, white pubescent or tomentose. Leaves opposite or subopposite, sometimes in whorls of 3; petiole ca. 1 mm; leaf blade green adaxially, grayish green abaxially, elliptic or ovate-orbicular to oblong, 1.5-5 × 0.8-2.8 cm, membranous, both surfaces sparsely strigose, glabrescent, base broadly cuneate to ± rounded, apex obtuse; lateral veins 5 or 6 pairs, slender. Inflorescences terminal, racemose, sometimes in small panicles; peduncle short. Calyx yellow; tube broadly cylindric, ca. 10 mm, exterior appressed hairy; lobes 4, elliptic, ca. 2 mm, reticulate veins obvious. Stamens 8, inserted in calyx tube. Disk scales 2, one linear and one oblong. Ovary stipitate, apex pubescent; style short; stigma capitate. Fruit not seen. Fl. autumn.
● Forests, shaded places on slopes; ca. 1100 m. Hubei, Sichuan.
When Halda published the nomen novum Daphne rehderi for this species (blocking name: D. gracilis E. Pritzel), he included D. rehderi subsp. techinensis (S. C. Huang) Halda, based on Wikstroemia techinensis S. C. Huang. Because the epithet of W. techinensis was available at species rank in Daphne and should have been so used (with W. gracilis as a subspecies), the name D. rehderi was nomenclaturally superfluous when published and is therefore illegitimate.
