摘要

摘要: 报道了产自云南天门冬科蜘蛛抱蛋属（Aspidistra Ker Gawler）一新种——辐射蜘蛛抱蛋（A.radiata G.W.Hu&Q.F.Wang）。该种与春秀蜘蛛抱蛋（A.chunxiuensis C.R.Lin&Y.Liu）相近，但该种因叶鞘3~4枚；总花梗较短，长5~9.5 cm，苞片5~7枚；花被裂片较多，常16（偶14或18）深裂，花被筒扁钵形，花被裂片较长，为65~76 mm，基部较宽，为13~16 mm；雄蕊16（偶14或18）枚；柱头上表面中央隆起区从中央向边缘具8（偶7或9）条呈辐射状排列的紫黑色、花瓣状隆起，每个花瓣状隆起的中央具沟槽等特征而与后者不同。辐射蜘蛛抱蛋亦与巨花蜘蛛抱蛋（A.grandiflora Tillich）近缘，但巨花蜘蛛抱蛋的叶片为狭倒卵形，（50×11）cm，基部狭楔形；花被裂片较短，为50~60 mm；柱头上表面中央具5条紫色辐射状的肋而有别于辐射蜘蛛抱蛋。

Abstract: A new species of Asparagaceae,Aspidistra radiata G.W.Hu & Q.F.Wang,from Yunnan,China,is described and illustrated.The new species is similar to A.chunxiuensis,but differs in its vaginate leaves 3-4,peduncle 5-9.5 cm long,with 5-7 bracts,perigone deeply 16 (occasionally 14 or 18) lobed apically; perigone tube alms bowl-shaped,inside with 16 (occasionally 14 or 18) keels on the mouth; lobes 65-76 mm long,13-16 mm wide at the base; stamens 16 (occasionally 14 or 18); bumped center of the stigma upper surface with 8 (occasionally 7 or 9) radiate,dark purple,petal-like ridges from the center to the margin,and a groove in each ridge.A.grandiflora is also similar to the new species,but differs in its leaf blade narrowly obovate,(50×11) cm,base narrowly cuneate; perigone lobes shorter,50-60 mm long; and stigma upper surface with 5 purple radial ribs in the center.
