Impatiens dalaiensis, a newly recorded species of Impatiens from Yunnan, China
-
摘要: 报道了中国凤仙花属一新记录种:紫花辐射凤仙花(Impatiens dalaiensis Gogoi&Borah)。该种分布于云南省腾冲县高黎贡山自然保护区,生长在常绿阔叶林下水沟边。本种主要辨别特征为:花轮生,紫色;唇瓣舟状,口部具芒;翼瓣远侧裂片长带状且螺旋扭曲。该种2015年发表时记载模式标本采自印度,而我们将原始文献中记录的模式标本采集点GPS经纬度信息标记于地图上时却发现,地点位于中国西藏自治区察隅县境内,故对原文记述的模式产地信息提出质疑。Abstract: Impatiens dalaiensis Gogoi & Borah is reported here as a newly recorded species in China. It is distributed in the Gaoligongshan Nature Reserve in Tengchong County, Yunnan Province, and grows in water ditches under evergreen broad-leaved forest. It differs from other related species by the following characters:flowers verticillate, purple; lower sepal navicular, aristate at mouth; distal lobe of lower petal long-lorate and twisted. The author who published this species stated that the type specimen was collected from India. However, when the type locality GPS latitude and longitude were marked on a map, the site was located in Chayu County, Tibetan Autonomous Region, China. Therefore, we question the type locality information recorded in the original description.
