Abstract
I NOTICE with interest Dr. Howard‘s records of chromosome counts of 2n = 56 for several plants of Cardamine pratensis growing in damp places1. I have been working on British plants of this species for the last two years, with the help and guidance of Dr. K. B. Blackburn, and I have collected a very considerable amount of information on its chromosome number. The normal plant which grows in damp meadows has constantly the chromosome number 2n = 56, judged from the evidence of seventy plants collected from eighteen vice-counties. Plants with semi-double flowers, first described by Dr. Wilfred Robinson2 in 1925, have been found in fifteen localities in wet places, chiefly in the north of England. They have the same chromosome number 2n = 56. Plants with 2n = 30 chromosomes seem to be characteristically from the south of England. Those examined include five normal plants and seven completely sterile double-flowered plants. No other chromosome numbers than these have so far been encountered.
