摘要:

该文报道了四川凤仙花属四新记录种,即睫毛萼凤仙花(Impatiens blepharosepala Pritz. ex Diels)、红纹凤仙花(Impatiens rubro-striata Hook. f.)、滇西北凤仙花(Impatiens lecomtei Hook. f.)及松林凤仙花(Impatiens pinetorum Hook. f. ex W. W. Smith),并进行了鉴定和讨论,同时提供了相关照片。凭证标本保存于西昌学院标本室(XIAS)中。我国西南地区是世界五大凤仙花属植物分布中心地区之一,此次在四川发现的四新记录种均为我国特有种,该发现对于研究我国西南地区凤仙花属植物的起源和扩散路线具有一定的指导意义。

Abstract:

Four new record species of Impatiens in Sichuan, China have been reported: Impatiens blepharosepala Pritz. ex Diels, Impatiens rubro-striata Hook.f., Impatiens lecomtei Hook. f., and Impatiens pinetorum Hook.f. ex W. W. Smith. The corresponding photos have been provided and their identifications have been discussed. The voucher specimens are preserved at the Herbarium of Xichang College(XIAS). Southwest China is one of the five major distribution areas of Impatiens plants around the globe. Each of those four new record species discovered in Sichuan is exclusively found in China. This discovery can guide the research of Impatiens plants in Southwest China regarding their origins and colonization routes to some extent.
