Taxonomic study of Himalayan Impatiens

为阐明凤仙花属喜马拉雅植物的特征，对凤仙花属植物进行了形态学和细胞遗传学研究。对日本凤仙花属植物进行了比较研究凤仙花是凤仙花中最独特的花。下萼片的距侵入到下萼片的内部。对这种独特的花作了详细的描述云南南部的凤仙花（Impatiens wuchengyii）、芦春凤仙花（I.luchunensis）、maguranensis、clavigeroides和线性凤仙花凤仙花（I.linearisepala） 5个新种。中国云南南部首次报道kamitilongensis和prophyrea两种。对云南15种凤仙花的染色体数目和核型进行了研究结果表明，中川凤仙花是小叶凤仙花的变种，几乎分布于小叶凤仙花变种的所有范围。

To clarify the characteristics of the Himalayan elements of the genus Impatiens (Balsaminaceae) the morphological and cytogenetical studies were carried. For the comparison Japanese plants of Impatiens were studied.1 Impatiens nubigena W.W.Sm.has the most uniquw flower in Impatiens. The spur of the lower sepal is intruding into the inside of the lower sepal. A detailed description of the unique flower was given.2 Five new species, Impatiens wuchengyii, I.luchunensis, I.maguranensis, I.clavigeroides and I.linearisepala were described from S Yunnan, China. Two species, I.kamitilongensis and I.prophyrea, were first reported from China (S Yunnan).Chromosome numbers and karyotypes of 15 species of Impatiens collected from Yunnan were investigated.3 Impatiens microhypophylla Nakai were cleared to be a variety of I.hypophylla and distibuted almost all the range of var.hypophylla.
