Abstract:

The present work reports the chromosome numbers of 30 species of 7 ge-
nera of Magnoliaceae in China.  The chromosome numbers of Liridendron chinense, Ma-
gnolia officinalis, M. liliflora, Michelia rigo and M. champaca are consistent with those
previously reported Magnolia denudata was reported 2n=114, but our result shows 2n=
76; M. grandiflora was reported 2n=112, 114, but here 2n=114. Chromosome numbers of
the other 23 species are reported for the first time.  Vouchers for experimental materi-
als have been preserved in Herbarium of the Department of Biology, Nankai University,
Tianjin.

Key words: Chromosome number, Magnoliaceae.
