The present paper reports the results of cytological studies of three samples of
comfrey introduced into China as forage plants. It is found that the chromosome numbers of these three different samples of comfrey are the same, 2n = 40. This number
is consistant with that of the Symphytum peregrinum Ledeb. in literature, but different
from that of the other species. Therefore from the view point of chromosome number
we consider preliminarily that these three samples of comfrey are identical withSymphytum peregrinum Ledeb.
