Abstract:
A report of chromosome numbers for eight species endemic to China is
made in the paper, including first counts for 4 genera and 4 species and first karyoty-
pic analyses of two species.
Sinojohnstonia chekiangensis (Migo) W. T. Wang (Boraginaceae) 2n=24*;
Coptis chinenis Franch (Ranunculaceae) 2n=18**;
Dichocarpum dalzielii (Drumm. et Hutch.) W. T. Wang et Hsiao (Ranunculaceae)
2n=24*;
Eomecon chionantha Hance (Papaveraceae) 2n=18;
Camptotheca acuminata Dcne. (Nyssaceae) 2n=44;
Calycanthus chinensis Cheng et S. Y. Chang (Calycanthaceae) 2n=22**;
Eucommia ulmoides Oliv. (Eucommiaceae) n=17;
Pinellia pedatisecta Schott (Araceae) 2n=26;
The previous reports of chromosome numbers of the same groups are compared with
our own (See Table 1). The vouchers for the present study are preserved in the Herba-
rium of Futan University.
