Anaphalis gracilis Hand. -Mazz., Symb. Sin. 7: 1103, t. 17, f. 5. 1936.
茎高5-30厘米，被白色蛛丝状棉毛，上部被白色棉毛。叶线形或线状披针形，长1-2.5厘米，宽0.1-0.3厘米，上面被蛛丝状毛或疏棉毛，下面被灰白色蛛丝状密棉毛，边缘反卷。
产四川西部及西北部（松潘、道孚、太宁、康定、雅江）。生于高山干旱坡地和石砾地，海拔3200-4000米。
形态特征：多枝亚灌木。根状茎粗壮，根出条或不育茎直立或斜升，有密生的枯萎宿存的叶和显明的腋芽和顶芽。花茎由腋芽长成，高5—40厘米或更高，常纤细．上部草质，不分枝，被蛛丝状毛或具柄腺毛，有较疏生的叶。叶开展或多少直立，线形、线状披针形或倒披针形，长1—3．5厘米，宽0．1—0．7厘米，基部等宽或渐狭，沿茎下延成狭或较宽绿色的翅，顶端急尖或渐尖，有小尖头，上部叶渐尖，有长尖头，边缘反卷，全部叶质厚，上面被蛛丝状棉毛或具柄腺毛、下面被蛛丝状密棉毛，中脉在下面高起。不育茎顶部叶较短，两面被白色密棉毛。头状花序5—50个密集成伞房或复伞房状。花序梗长1—2毫米。总苞狭钟状，长4—5毫米，径4稀6毫米；总苞片约6层，外层宽卵圆形，稍尖，长1．5毫米，褐色，被棉毛，内层舌状椭圆形，长3—3．5毫米，宽1毫米，在雄株常达1．5毫米，白色，顶端钝或圆形，最内层长约4毫米，有长达全长四分之三的爪部。花托有缝状突起或短毛。雌株头状花序外围有多层雌花，中央有1—4个雄花；雄株头状花序全部是雄花。花冠长约3毫米。冠毛较花冠稍长；雄花冠毛上部较粗扁，有锯齿。瘦果长圆形，长约1毫米，被密乳头状突起。花期7—8月，果期8—9月。
产地分布：产四川西部及云南西北部。
本种提示：此种有相当大的变异。生长习性与亚灌木香青A．SuffruticosaHand．Mazz．接近。粗壮的植株有时略似二色香青的同色变种A．Bicolorvar．Subcon·colorHand．·Mazz·，但后者的头状花序较大。此种花枝纤细，径0．8—2毫米，但根状茎径达1厘米或更粗壮，有时花茎丛生于根状茎上。

Subshrubs. Rhizome thickish; sobols or sterile stems erect or ascending, densely withered, marcescent leafy and with distinct axillary buds and terminal buds. Flowering stems arising from axillary buds, 5-40 cm or more, often slender, upper parts herbaceous, simple, tomentose or cauliferous glandular pilose, sparsely leafy. Leaves expanding or somewhat erect, linear, linear-lanceolate, or oblanceolate, 1-3.5 × 0.1-0.7 cm, uniformly wide or base attenuate, decurrent on stem into a narrow or broad green wing, apex acute or acuminate, with short cusp; upper leaves acuminate, with long cusp, margin revolute; all leaves thickly arachnoid tomentose or cauliferous glandular pilose. Capitula 5-50, densely corymbiform or compound corymbiform; peduncle 1-2 mm. Involucre narrowly campanulate, 4-5 mm, rarely to 6 mm; phyllaries ca. 6-seriate, expanding; outer phyllaries brown, broadly ovate, ca. 1.5 mm, tomentose, slightly acute; middle ones lingulate-elliptic, 3-3.5 × ca. 1 mm, ca. 1.5 mm wide in male capitula, apex white, obtuse or rounded; innermost ones ca. 4 mm, with a ca. 3/4 of full length claw. Receptacle with fimbrillate appendage. Predominantly female capitula with numerous marginal female florets, center with 1-4 male florets; predominantly male capitula with male florets only. Corolla tube ca. 3 mm. Pappus slightly exceeding corolla, incrassate at tip of apex in male florets, serrulate. Achenes oblong, ca. 1 mm, densely papillose. Fl. Jul-Aug, fr. Aug-Sep.
