| Abstract: | The new species of Allium L. , A. maowenense 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 re-
ports 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 clear-ly. The karyotypic asymmetry belongs to Stebbins’ 2A type. |
