Taxonomic study of Sino-Himalayan Impatiens

凤仙花属植物在世界上分布广泛，中国-喜马拉雅地区是凤仙花属植物的分布中心之一。为阐明凤仙花属中国喜马拉雅成分的特征，对凤仙花属植物进行了形态学和细胞遗传学研究。为了比较，还研究了日本凤仙花属植物.对花器官的形态变异进行了研究.对主要标本馆保存的标本和日本种进行了调查.染色体数目及核型分析.对物种的划分进行了研究.对花序的形态特征进行了研究，并对属下类群进行了识别和比较。

The genus Impatiens (Balsaminaceae) is widely distributed in the world and the Sino-Himalayan region is one of the center of the diversification. To clarify the characteristics of the Sino-Himalayan elements of the genus Impatiens the morphological and cytogenetical studies were carried. For the comparison Japanese plants of Impatiens were also studied.1. The morphological variation of the floral organ were investigated.2. The specimens deposited in the main herbaria and Japanese species were investigated.3. The chromosome numbers and karyotypes were observed.4. The species delimitation is studied.5. The morphological characters of the inflorescences were investigated and the infrageneric groups were recognized and compared.
