常绿大乔木，高达20米，树干具板状基部，有时有气根；树皮淡绿灰色，光滑，浅纵裂或龟裂，有时具瘤状体，内皮黄色、浅棕色至浅红色；小枝初近四棱形，后为圆柱形，灰褐色，具纵皱纹或条纹，有白色圆形皮孔；顶芽椭圆状至倒卵圆形，扁平。叶厚纸质或近革质，倒卵形，有时椭圆形，长10-18厘米，宽6-10厘米，顶端骤尖或短尖，基部渐狭或楔形，常渐狭窄，两面均无毛；侧脉5-7对，无毛，脉腋窝无毛；叶柄长0.8-1.5厘米或稍过之，粗壮而无毛；托叶倒卵形或倒卵状长圆形，无毛。总花梗1-3条；头状花序不计花冠直径8-12毫米；小苞片存在；花萼管上部有苍白色短柔毛，萼裂片密被苍白色毛，长3.5-4.5毫米；花冠窄漏斗形或高脚碟状，花冠管的外面无毛，花冠裂片长圆形，两面均无毛；花柱伸出。果序直径20毫米；小蒴果被短柔毛，顶部有宿存的花萼裂片。花、果期9-12月。

Trees, evergreen, to 20 m tall; trunk often buttressed at base, sometimes with aerial roots; bark greenish gray, fissured and cracked, sometimes warty, with inner bark yellow, pale brown to pink; branchlets quadrangular becoming terete, grayish brown, rugose or striate, white lenticellate, glabrescent. Petiole 8-20 mm, stout, glabrous; leaf blade drying thickly papery to subleathery, obovate to elliptic, 8-22 × 4-15 cm, both surfaces glabrous, base acute to cuneate and frequently decurrent, apex rounded then abruptly cuspidate or acute; secondary veins 5-7 pairs, in abaxial axils with glabrous domatia; stipules obovate to obovate-oblong, 5-10 × 3-8 mm, weakly keeled, glabrous, apex obtuse. Inflorescences puberulent to glabrescent; peduncles 1 or 3, 2-6 cm; flowering heads solitary, 8-12 mm in diam. across calyces, 25-30 mm in diam. across corollas; involucral bracts not seen; bracteoles 0.5-1 mm. Calyx with ovary portion obconic, 1-1.5 mm, glabrous in lower 2/3, pilosulous in upper 1/3; limb partially lobed, with basal tubular portion ca. 1 mm; lobes with shaft clavate, 3.5-4.5 mm, densely pilosulous, with apical portion fusiform, deciduous before corollas open, pilosulous on lower portions, glabrous at apex. Corolla red (Henry 12676, MO!), narrowly funnelform to salverform, outside glabrous; tube 7-8 mm, inside glabrous to sparsely pubescent; lobes elliptic-oblong, 2-3 mm, acute. Stigmas subglobose, ca. 1 mm, exserted for 5-6 mm. Fruiting heads ca. 20 mm in diam. Capsules obconic, 5-6 mm, pilosulous at least at apex; seeds not seen.
Dense forests in valleys or on humid slopes; 800-1300 m. Guangxi, Guizhou, Yunnan [Bhutan, N India, Myanmar].
