Cyananthus flavus Marq., Kew Bull. 247. 1924; Tsoong, Contr. Inst. Bot. Nat. Acad. Peiping 3 (3): 106. 1935.
多年生草本。茎基粗壮，顶部具宿存的鳞片，鳞片长卵形，长约3毫米，宽约1毫米。茎数条并生，上升，长7-12厘米，不分枝或有短分枝，密生灰白色开展的长柔毛。叶互生，唯花下4或5枚叶聚集呈轮生状，自茎下部向上逐渐增大，较密生，几无柄；叶片椭圆形或卵圆形，长5-14毫米，宽3-8毫米，两端锐尖，边缘反卷，全缘，两面生灰白色开展柔毛，或无毛。花单生于茎顶端，花梗长1-2厘米，无毛或疏生短毛；花萼短筒状，底部浑圆，果期膨大，筒长宽近相等，8-10毫米，无毛，裂片三角形，长宽均约3毫米，内面生柔毛；花冠黄色或淡黄色，长2.5-2.7厘米，外面无毛，内面喉部密生白色柔毛，裂片倒卵状矩圆形或倒卵状椭圆形，长1.4-1.6厘米，宽5-7毫米，顶端常生几根锈色柔毛；子房花期约与萼筒等长，花柱超出花冠筒。花期7-8月。
本种叶片椭圆形或卵圆形，长5-14毫米，宽3-8毫米，两端急尖，全缘；花冠黄色或淡黄色，裂片长于筒部，有别于相近种类。模式标本采自云南（丽江）。本种包含有两个变种。

黄钟花 huang zhong hua
Roots carrot-shaped, up to 5 mm in diam. Caudexes robust, multibranched, covered with persistent scales toward apex; scales ovate, ca. 3 × 1 mm. Stems caespitose, ascending, 5.5-16 cm, simple or with short branches, densely white villous to subglabrous. Leaves alternate, gradually increasing in size toward apex, sessile or nearly so; blade elliptic, obovate-lanceolate, or broadly ovate, 5-16 × 3-8 mm, both surfaces gray-white hirsute or glabrous, base cuneate, margin entire or sometimes slightly sinuate, slightly recurved, apex acute, obtuse, or rounded. Flowers solitary and terminal, subtended by a whorl-like aggregation of 4 or 5 leaves; pedicel 1-2 cm, usually glabrous, rarely sparsely hirsute. Calyx glabrous, except yellow hirsute inside lobes; tube broadly cylindrical, 8-12 mm, base rounded or truncate, enlarging in fruit; lobes triangular, 3-4 × ca. 3 mm. Corolla white or various shades of yellow, 2.5-3 cm, outside glabrous, inside densely white- or yellow villous at throat; lobes obovate-oblong or obovate-elliptic, 14-16 × 5-7 mm, apex often very sparsely brown villous. Capsule subequal to calyx in length; style exceeding corolla tube. Fl. Jul-Aug.
