Aster brachytrichus Franch. in Journ. de Bot. 10: 372. 1896.
多年生草本，根状茎粗壮，木质。茎直立，高15-50厘米，单生或丛生，不分枝，被疏或下部被密长毛，有等距或上部疏生的叶。莲座状叶匙形，长5-10厘米，宽1.5-3.5厘米，下半部渐狭成长柄；下部叶在花期常枯萎，较小，下部及中部叶卵圆形，长圆形或卵圆披针形，长2-9厘米，宽0.5-4.5厘米，基部圆形或稍狭，顶端圆形或稍尖，无柄，半抱茎，全缘或有疏齿；上部叶稍小；全部叶质薄，两面被疏毛或上面无毛，或被密毛，下面沿脉及边缘有开展的长毛；中脉及离基三出脉在下面稍高起或另有2细边脉。头状花序在茎端单生，径4-7.5厘米。总苞半球形，径1-2厘米，远超出花盘；总苞片2-3层，草质，长10-13毫米，宽1-4毫米；外层顶端尖或钝，沿脉有长毛，有缘毛，稀无毛；内层线状披针形稀线形，渐尖，有缘毛。舌状花30-50个或更多，管部长不及1毫米；舌片蓝色或紫色，长15-35毫米，宽1-3毫米；管状花橙黄色，长4-6毫米，外面无毛，管部长1.5-2毫米，裂片长1毫米；花柱附片长0.5毫米。冠毛1层，长约2毫米，基部黄色，干膜质，上部紫褐色，有不等长的糙毛。瘦果极扁，心状卵圆形，长4毫米，宽2-2.7毫米，下部渐狭，边缘有翅，无毛或上部有短缘毛，或两面近顶端有短毛。花期6-8月；果期8-10月。
产于云南西北部及北部，四川南部。也分布于缅甸北部。
此种的冠毛及瘦果在本组中至为特殊。叶形多变异，在模式植物上倒卵状长圆形，但有时宽卵形而两端渐狭，有时茎上部渐小渐尖与下种 (A. jeffreyanus Diels) 极难区别。头状花序的大小，总苞片从无毛至沿中脉或全部有毛，瘦果从无毛至上部有短毛或缘毛，也有一系列的变异。可分为下列各变种：

短毛紫菀 duan mao zi wan
Aster bodinieri H. Léveillé.
Herbs, perennial, 10-50 cm tall, sometimes caespitose; rhizomes robust, woody. Stems erect, simple, densely pilose proximally and apically, sparsely to moderately so at midstem, moderately to densely minutely stipitate glandular, usually regularly leafy. Leaves basal and cauline; cauline leaves slightly and gradually reduced upward, sparsely to moderately pilose or glabrous, veins villous abaxially, margin sparsely shallowly serrate or serrulate, sometimes entire, pilose-ciliate, triplinerved abaxially, veins slightly prominent; basal leaves usually withered at anthesis, long petiolate (petiole to 4 cm); blade spatulate to obovate or oblanceolate, 1-6 × 0.6-3.5 cm, base attenuate, apex rounded to obtuse; lower and middle cauline leaves sessile, ovate or ovate-lanceolate to oblong, 2-7 × 0.5-3 cm, base rounded or attenuate, subclasping, apex rounded to acute; upper leaves ovate to linear-lanceolate, 1-3.5 × 0.2-1.8 cm. Capitula terminal, solitary, 3-7.5 cm in diam. Involucres hemispheric, 1-2 cm in diam., overtopping disk florets; phyllaries 2- or 3-seriate, subequal, squarrose, 10-13 × 1-4 mm, sparsely pilose to glabrate, sometimes inner phyllaries sparsely minutely stipitate glandular distally, margin whitish, pilose-ciliate; outer phyllaries linear-lanceolate to oblong, leaflike, apex acute to obtuse; inner phyllaries linear-lanceolate to linear, apex long acuminate. Ray florets 30-60, blue to purplish, tube less than ca. 1 mm, lamina 15-35 × 1-3 mm, glabrous, eglandular; disk florets orange becoming reddish, 3.5-5 mm, limb funnelform becoming ± campanulate distally, 2.5-4 mm, glabrous, lobes spreading, narrowly triangular, 0.8-1.5 mm. Achenes obovoid, ± compressed, 2.5-4 mm, glabrous, sparsely minutely stipitate glandular apically, margin winged, 2-ribbed, plus sometimes 2- or 3-ribbed on each side. Pappus series reduced, indistinguishable, sometimes basally fused, purple brown to brown; bristles flattened, barbellate throughout, 1-4 mm, acute. Fl. Jun-Aug, fr. Aug-Oct.
