A karyological study of seven species and one variety of Cymbidium from China

Abstract

Abstract: Seven species and one variety of Cymbidium are karyologically analyzed: C. qiubeiense K. M. Feng et H. Li (2n = 40 = 24m + 12sm + 4st), C. faberi Rolfe (2n = 40 = 30m + 8sm + 2st), C. faberi var. szechuanicum (Y. S. Wu et S. C. Chen) Y. S. Wu et S. C. Chen (2n = 40=26m+ 10sm + 4st), C. kanran Makino (2n = 40 = 26m + 12sm + 2st), C. cyperifoliumWall. ex Lindl. (2n = 40 = 24m + 12sm + 4st), C. goeringii ( Rchb. f. ) Rchb. f (2n = 40 =24m+ 10sm+4st+2t), C. longibracteatum (Y. S. Wu et S. C. Chen)Y. S. Wu et S. C.Chen (2n = 40 = 24m + 10sm + 6st) and C. serratum (Schltr) (2n = 40 = 28m + 10sm + 2st). In C. serratum, however, counts of 2n = 41, 43, 60, 80 are of occasional occurrence.

Key words: Cymbidium, Chromosome number, Karypotype
