Taxonomic study of Sino-Himalayan Impatiens

凤仙花属植物广泛分布于世界各地，中国-喜马拉雅地区是凤仙花属植物多样性的中心之一。为了阐明凤仙花属中国-喜马拉雅成分的特征，对凤仙花属植物进行了形态和细胞遗传学研究。为了进行比较，还研究了日本凤仙花属植物。对花器的形态变异进行了观察。对保存在主要草本植物和日本种的标本进行了调查。观察染色体数目和核型。对物种划分进行了研究。对花序的形态特征进行了观察，并对属下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.
