Cotoneaster rubens W. W. Smith in Not. Bot. Gard. Edinb. 10: 24. 1917; Hand. -Mazz. Symb. Sin. 7: 457. 1933; Yu in Bull. Brit. Mus. Bot. 1: 131. 1954; Klotz in Wiss. Zeits. Univ. Halle 6: 971. 1957; Hara, Fl. E. Himal. 2: 51. 1971.
形态特征：直立或匍匐落叶至半常绿灌木，高0．5—2米，常具不规则分枝；小枝粗壮，圆柱 形，灰黑色，幼嫩时具糙伏毛，老时无毛。叶片近圆形或宽椭圆形，长1—2．3厘米，宽 0.8—1.8厘米，先端圆钝而常具小突尖，基部圆形，全缘，上面无毛，叶脉下陷，下面密 被黄色绒毛，叶脉突起：叶柄粗壮而短，长1—2毫米，具柔毛：托叶早落。花多数单 生，直径8—9毫米，具短梗；萼筒钟状，外面具稀柔毛，内面无毛；萼片三角形，先端稍 钝，外面有柔毛，内面仅沿边缘处有柔毛：花瓣直立，圆形至宽倒卵形，直径4—5毫 米，先端钝，深红色：雄蕊约20，比花瓣短：花柱2，离生，稍短于雄蕊；子房顶端具柔 毛。果实倒卵形，直径8--9毫米，红色，具小核2或3。 花期6--7月，果期9—10 月。
产地分布：产云南西北部和西藏东南部。生于山坡密林中或林缘草地，海拔3000--4100米。 模式标本采自云南中甸。缅甸、不丹也有分布。
本种提示：此种和单花栒子C．Unifiorus Bge．比较，区别在于本种的叶片多数近圆形，先端 钝，下面密被黄色绒毛，花红色，萼筒外面有毛，而后者叶片多数卵形，先端急尖稀圆 钝，老时下面近于无毛，花粉色，萼筒外面无毛。

红花栒子 hong hua xun zi
Shrubs deciduous to semievergreen, erect or prostrate, 0.5–2 m tall, usually irregularly branched. Branchlets grayish black, terete, robust, initially strigose, glabrous when old. Petiole short, 1–2 mm, stout, pubescent; stipules caducous; leaf blade suborbicular or broadly elliptic, (0.8–)1–2.3 × (0.6–)0.8–1.8 cm, veins raised abaxially and impressed adaxially, abaxially densely yellow tomentose, adaxially glabrous, base rounded, apex obtuse or mucronate, rarely acute. Inflorescences usually 1-flowered. Flowers 8–9 mm in diam., shortly pedicellate. Hypanthium campanulate, abaxially pilose. Sepals triangular, 1–2 × 1.5–2.5 mm, apex ± obtuse. Petals erect, dark red, orbicular to broadly obovate, 4–5 mm in diam., apex obtuse. Stamens 20, shorter than petals. Ovary pilose apically; styles 2 or 3, free, somewhat not exceeding stamens. Fruit red, obovoid, 8–9 mm in diam., pyrenes 2 or 3. Fl. Jun–Jul, fr. Sep–Oct.
Dense forests on slopes, forest margins, grasslands, rocky places; 3000--4100 m. W Sichuan, SE Xizang, NW Yunnan [Bhutan, N Myanmar].
