灌木，高0.2-1米或稍过之；小枝纤细，灰色至淡褐色，被微柔毛，表皮薄，常片状剥落。叶纸质，披针形或长圆形，有时椭圆形或近卵形，长通常0.7-2.5厘米，很少达3厘米，宽0.3-1厘米或稍过之，顶端渐尖或短渐尖，稍钝头，基部渐狭或有时短尖，上面粗糙，下面被短柔毛或近无毛；侧脉每边约3条，下面明显，网状小脉两面不明显；叶柄短，通常不超过3毫米；托叶长约1.5毫米，基部阔三角形，顶端骤尖，尖头硬。花无梗，常3-7朵簇生枝顶，很少在小枝上部腋生；小苞片透明，卵形，长约3毫米，外面被柔毛，约2/3至1/2合生，裂片近三角形，顶端有硬尖头，与萼近等长；萼裂片阔卵形，长约1.3-1.5毫米，顶端钝，边缘密生缘毛；花冠淡紫红色，漏斗状，长11-14毫米，有时可达20毫米，外面被微柔毛，冠管狭长，下部常弯曲，裂片狭三角形或披针形，长约2-4毫米，顶端内弯；短柱花雄蕊微伸出，花药线形，长柱花内藏，花药线状长圆形；花柱具4-5个线形柱头裂片，长柱花微伸出，短柱花内藏。蒴果长5-6毫米，种子有网状、与种皮分离的假种皮。花期6-8月，果期10月。
产我国华北，西至陕西汉中（？）南至河南北部，尤以河北最常见。生于山坡、路边等向阳处，亦见于灌丛中。模式标本产北京或其邻近地区。
本种叶和花的大小常有变异，因此，H. Winkl. 将叶和花较大的类型建立一变种var. leptophylla H. Winkl. 似无必要。此外，产于日本的 L. pulchelta Yatabe 与上述变种几无区别，因此也很可能应归并于本种。
过去有的文献记录本种也分布至湖北，陕西等地。据目前所见标本，多为鉴定错误所造成的。

Shrubs, 0.2-1 m tall or slightly taller; branches slender, gray to pale brown, puberulent, bark thin, usually peeling off when old. Petiole short, 1-3 mm; leaf blade papery or thinly leathery, lanceolate or oblong, sometimes elliptic or subovate, usually 0.7-2.5(-3) × 0.3-1(-1.7) cm, adaxially scabrid or irregularly wrinkled and sparsely strigose, abaxially subglabrous or pubescent or hispid along midrib, base attenuate or cuneate, margins revolute, apex acuminate, subacute, or obtuse; lateral veins ca. 3 pairs, inconspicuous on both surfaces; stipules broadly triangular, 1.5-2 mm, cuspidate with a stiff apiculus.

Calyx tube ca. 2.5 mm; lobes subovate, ca. (0.7-)1.3-1.5 mm, densely shortly ciliate, obtuse or shortly acuminate. Corolla purplish red, funnelform, (9-)11-14(-20) mm; tube slender, often curved, puberulent outside; lobes subovate, narrowly triangular, or lanceolate, 2-4 mm, apex incurved.
