| 摘 要： | The paper reports chromosomal number and chromosomal morphologies of
annual Aconitum gymnandrum endemic to China and Beesia calthifolia for the first
time. Of the two spcies, chromosome number is same (X=8, 2n=16) and chromosome
average lengths are 6.17μ , 10.73μ respectively. The longest chromosome 1, the short
chromosomes 3-5, 7 and the shortest chromosome 8 are metacentrical (m), the chro-
mosomes 2, 6 are submetacentrical (sm), and the pairs 4, 5, 8 have satellites in the
karyotype of A. gymnandrum. In B. calthifolia, all of the chromosome 1-5 are the
long m, the chromosomes 6, 8 are the short sm and the 7 is telocentrical (t). The pairs
3, 4, 6 have satellites.
According to the comparison of karyotypes of three subgenera—subgen. Para-
conitum, subgen. Aconitum and subgen. Gymnaconitum in Aconitum, the evolution trend
of chromosomes is further discussed.
Finally, the relationship between Aconitum and Beesia is also discussed in thispaper.
