A NEW SPECIES OF ALLIUM L.FROM SICHUAN AND ITS KARYOTYPE
|
Abstract:
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.
