摘要
报道了产自云南麻栗坡的兰科兰属一新杂种——麻栗坡长叶兰(Cymbidium×malipoense L.J.Chen,H.B.Zhou&Z.J.Liu),对该种的形态特征进行了描述。该种可能是长叶兰(Cymbidium erythraeum Lindl.)与龙州兰(C.eburneum var.longzhouense Z.J.Liu et S.C.Chen)的天然杂交种。本种与长叶兰的区别是:本种的花葶自叶腋发出;萼片和花瓣浅黄绿色,具浅紫红色的纵条纹和斑点;唇盘具黄色褶片;蕊柱浅紫红色;中裂片卵状肾形。长叶兰的萼片和花瓣绿色,有红褐色脉纹和不规则斑点;中裂片心形到剑形;唇盘密被毛。本种与龙州兰的区别是:本种萼片和花瓣浅黄绿色,具浅紫红色的纵条纹和斑点;侧裂片有紫红色条纹;蕊柱浅紫红色。龙州兰萼片和花瓣白色,外表面略带粉红色;唇瓣白色,侧裂片和中裂片具有紫红色斑点。
Cymbidium×malipoense L.J.Chen,H.B.Zhou&Z.J.Liu,from Malipo County,Yunnan Province,China,is described and illustrated as a new hybrid species of Orchidaceae.This new species may be a natural hybrid between Cymbidium erythraeum Lindl.and C.eburneum var.longzhouense Z.J.Liu et S.C.Chen.It differs from C.erythraeum by:scape arising from axils of leaves;sepals and petals pale yellow-green,distinctly marked with reddish-brown longitudinal stripes and irregular spots;disc with yellow lamellae;column pale purple-red,and mid-lobe cordate to reniform.Cymbidium erythraeum differs from the new species by:sepals and petals green with heavy reddish-brown longitudinal stripes and irregular spots;mid-lobe cordate to ensiform;and disk densely hairy.The new species differs from C.eburneum var.longzhouense by:sepals and petals pale yellow-green,distinctly marked with reddish-brown longitudinal stripes and irregular spots;side-lobe with purple-red stripes;and column pale purple-red.Cymbidium eburneum var.longzhouense differs from the new species by:sepals and petals white,usually tinged pink on outer surfaces;and lip white,conspicuously mottled purplish pink on lateral lobes and mid-lobe.
