| 摘 要： | 本文对湖南产的宝锋草（ＤｉｓｐｏｒｕｍｓｅｓｓｉｌｅＤ．Ｄｏｎ）和广西产的长穗开口箭（ＴｕｐｉｓｔｒａｌｏｎｇｉｓｐｉｃｇＹ．ＷａｎｅｔＸ．Ｈ．Ｌｕ）的核型作了分析。前者的核型公式为２ｎ＝１４＝４ｇ＋１０ｓｍ（２ｓａｔ），核型类型属于３Ａ；后者的核型公式为２ｎ＝３８＝２４ｍ＋６ｓｉｎ＋８ｓｔ．核型具有明显的二型性，属于２Ｃ型。此外还讨论了宝锋草的核型变异以及开口箭属和蜘蛛抱蛋属（Ａｓｐｉｄｉｓｔｒａ）的关系。

| Abstract: | In this paper, karyotypes of Disporum sessile from Hunan and Tupistra longispica from Guangxi were reported. The karyotype of D.sessile was formulated as 2n=14=4m+10sm (2sat) and belonged to 3A type, and that of T.longispica was formulated as 2n=38=24m+6sm+8st and bimodal, and belonged to 2C type.In addition,haryotypic variations in D. sessile and the relationship between Tupistra and Aspfdistra were preliminarily discussed. |
