摘要
描述了延龄草科一新变种——攀西直瓣重楼(Paris polyphyllaSmith var.panxiensisJ.L.Liu),并绘制了形态图。新变种以其叶片狭长、条形而与狭叶重楼(Paris polyphyllaSmith var.stenophyllaFranch.)和小重楼(Paris polyphyllaSmith var.minorS.F.Wang)相近似,但又以花瓣线状圆柱形、直立、不弯曲、远短于萼片、向上逐渐增粗呈棒状、先端圆形或钝圆,花药药隔明显头状突起而有明显区别。
Paris polyphylla Smith var. panxiensis J. L. Liu, a new variety of the Trilliaceae from Sichuan, China,is described and illustrated. It is closely related to Paris polyphylla Smith var. stenophylla Franch. and Paris polyphylla Smith var. minor S. F. Wang by its leaf blade narrowly long and fasciate, but differs in having petals linearis-terete, erect and never curved, much shorter than sepals, up to thick to clavellate gradually,rounded or obtusely rounded at the apex,anther connective obviously capitate-protruding.
