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. cyperifolium Wall. 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.更多还原
