灌木，高0.2-1.3米，具纤细的分枝；嫩枝被极短的绒毛，很快无毛，老时具灰色纵裂的树皮。叶在长枝上疏生，着生在其腋中的极短枝条上的叶极密挤，使长枝上的叶具轮生的外貌，叶片长圆形或卵形，长4-9毫米，宽1.25-2毫米，基部或顶部宽，顶端短尖或稍钝或具细尖头，基部渐狭，两面无毛；中脉在上面压入，下面凸起，侧脉不明显；叶柄极短或近无柄；托叶膜状革质，小，长约1毫米，上部的三角形，下部的刺状渐尖，边缘或靠近边缘有2条胼胝质脉直贯顶端，被柔毛和缘毛。花于具叶近长的侧枝上顶生，此外在上部2-3个节上的每一叶腋均生花1-3朵，总花梗有或几无；小苞片合生至中部或中部以上，透明，有脉纹，长圆形，长约2毫米，顶端圆，有细尖头，上部边缘有毛，余无毛，比萼稍长；萼裂片5，长稍超过宽，顶端圆，有缘毛；花冠小，管狭漏斗形，长约5毫米，多少弯，外面被圆锥状绒毛，里面喉部密被长毛，基部无毛，裂片长圆形，长约2毫米，顶端内弯，有柔薄的狭边，外面有短乳突，里面基部被长柔毛；雄蕊生冠管喉部；长柱花：花丝短，花药内藏；短柱花：花丝长，花药伸出；柱头5裂，长柱花明显伸出，短柱花伸出喉部下方。蒴果长约4毫米；种子的假种皮紧贴种皮。
产四川西北部和中部、云南西北部、西藏波密。模式标本采自云南维西茨开。
本种与 L. purdornii 的区别是：苞片长于萼；萼裂片钝。

Leptodermis schneideri var. hutchinsonii H. J. P. Winkler.
Shrubs, 0.2-1.3 m, branches slender; young branches tomentulose, soon glabrescent, old branches with gray longitudinally fissured bark. Leaves sparsely arranged on long branches, very crowded on very short branches in axils of long branches, appearing as if leaves whorled; petiole very short or leaves subsessile; blade oblong or ovate, 4-9 × 1.25-2 mm, glabrous on both surfaces, base attenuate, apex acute or slightly obtuse or apiculate; midrib impressed adaxially and prominent abaxially, lateral veins inconspicuous; stipules membranous-leathery, small, ca. 1 mm, pilose and ciliate, upper portion triangular, lower part acicular acuminate, with 2 callose nerves near margins extending to apex. Flowers terminal on lateral foliate branches, upper 2 or 3 nodes with 1-3 flowers axillary; peduncles present or almost absent; bracteoles transparent, oblong, ca. 2 mm, slightly longer than calyx, connate to or above middle portion, margins of upper portion hairy, apex rounded, apiculate. Calyx lobes 5, length slightly greater than width, ciliate, rounded. Corolla small; tube narrowly funnelform, ca. 5 mm, ± curved, covered with conical woolly hairs outside, densely covered with long hairs on throat inside, glabrous at base; lobes oblong, ca. 2 mm, covered with short papilla outside, villous at base inside, with thin, soft, narrow margins, apex incurved. Stamens inserted in throat of corolla tube; long-styled flowers with filaments short, anthers included; short-styled flowers with filaments long, anther exserted. Stigmas 5-lobed, conspicuously exserted in long-styled flowers, extending below throat in short-styled flowers. Capsules ca. 4 mm; seed aril adherent to testa.
