Peucedanum henryi Wolff in Fedde, Repent. Sp. Nov. 33: 248. 1933.
植株高约50厘米。根长纺锤形，不分枝，径约1厘米，木质化。茎圆柱形，坚硬，略呈空管状，分枝稀疏而细长。基生叶小，叶柄与叶片近等长，具极短叶鞘；叶片三出式三回分裂（？），羽片具长柄，小叶楔状倒卵形或卵形，长达20厘米，宽14厘米，但通常都较小，无柄或具短柄，坚实，下表面粉绿色，近于深裂，具狭裂片或小裂片。伞形花序很少，花序梗和伞辐等长；无总苞片和小总苞片；伞辐5-6，不等长，长达5厘米，最后叉开；小伞形花序有花近20，花柄丝状，近等长；萼齿显著，细小；花瓣长圆形，非常弯曲，顶端细，小舌片内曲，淡黄色至黄绿色（？），具及顶的分枝脉纹；花柱基非常发达，圆锥形，花柱反曲。果实椭圆形，背部十分扁压，无毛且平滑，分生果有时弯曲，略呈肾形，背棱线形，侧棱极狭窄，棱槽内油管3-4，合生面油管4，胚乳腹面后期凹入。模式标本（Henry no. 3604）采自湖北宜昌。

鄂西前胡 e xi qian hu
Plants to 50 cm. Stem rigid, hollow, sparingly branched, branches slender and elongate. Basal leaves small; petioles about equaling leaf blades, sheaths very short; leaf blade 3-ternate, pinnae long-petiolulate; pinnules sessile or subsessile, cuneate-obovate or ovate, ca. 20 × 14 mm, abaxially glaucous, parted or lobed. Synflorescence little-branched; peduncles equaling rays; bracts absent; rays 5–6, unequal, spreading in fruit; bracteoles absent; umbellules ca. 20-flowered; pedicels filiform, subequal. Calyx teeth conspicuous, small. Petals yellowish, oblong, with a narrow and very inflexed apex. Styles long. Mature fruit unknown, developing fruit ellipsoid, smooth; dorsal ribs filiform, lateral ribs narrowly winged; vittae 3–4 in each furrow, 4 on commissure. Fl. Jul.
Mountain slopes. W Hubei (Yichang).
This species is recorded only from the holotype (A. Henry 3604, K).
