摘要
本文分析了该新种的核型,其核型公式为K(2n)=2x=16=14m+2st(2SAT),具一对居间随体,有时该居间随体不明显。核型的不对称性为2A型。
The new species of Allium L. , A. maawenense J. M. Xu, from Sichuan Province is described in this paper. It is similar to A. eusperma Airy-Shaw, but differs from the latter by white flowers and filaments about 2 times longer than tepals. The present paper also reports the karyotype of the new species. The karyotypic formula was K (2n) =2x=16=14m + 2st (2SAT) with one pair of intercalary satellites, which sometimes were not found clearly. The karyotypic asymmetry belongs to Stebbins' 2A type.
