秋山，s .，若林，m .和大叶，h ., 1992。喜马拉雅凤仙花的染色体进化。对喜马拉雅凤仙花的染色体数目和核型进行了研究。除了证实先前的染色体计数外，还揭示了四倍体分类群（I. exilis）的存在。在尼泊尔中部和东部，具有x= 9的物种比具有其他基本数字的物种更常见，并且该数字被证明是该属中最常见的数字之一。大多数x= 9的物种具有双峰核型。讨论了物种关系。
AKIYAMA, S., WAKABAYASHI, M. & OHBA, H., 1992. Chromosome evolution in Himalayan Impatiens (Balsaminaceae). Chromosome numbers and karyotypes have been investigated in species of Himalayan Impatiens. In addition to confirming previous chromosome counts, the presence of a tetraploid taxon (I. exilis) is revealed. In central and east Nepal species with x= 9 are more common than those with other basic numbers and this number is shown to be one of the most frequent numbers in the genus. Most species with x= 9 have a bimodal karyotype. The species relationships are discussed.
