Abstract:
The present paper deals with the karyotype analysis of 12 species in Angelica and
three related genera-Czernaevia, Archangelica and Coelopleurum from China. Ten kary-
otypes are reported for the first time. The parameters of chromosomes of 12 species are given
in Table 1 and the karyotypes are shown in Plates 1, 2, 3. The karyotype formulae are as
follows: A. dailingensis Z. H. Pan & T. D. Zhuang 2n= 22= 20m+2sm (SAT); A. likian-
gensis Wolff 2n=22=18m+4sm; A. nitida Wolff 2n=22=14m+4sm+4sm (SAT); A.
silvestris L. 2n=22=16m+4sm (SAT) +2st (SAT) ; A. decursiva (Mig.) Fr. & Sav.
2n=22=16m+4sm+2sm (SAT); A. tsinlingensis K. T. Fu 2n=22=18m+4sm; A. a-
paensis Shan & Yuan 2n=22=14m+6sm+2st (SAT); A. oncosepala Hand. -Mazz. 2n=
4x=44=28m+12sm+4st; A. ternata Rgl. & Schmalh. 2n=22=10m+8sm (SAT)+
4st (SAT); Czernaevia laevigata Turcz. 2n=22=14m+6sm+2sm (SAT) ; Archangelica
brevicaulis (Rupr.) Rchb. 2n=22=8m+2m (SAT) +4sm+4sm (SAT) +4st; Coelopleu-
rum saxatile (Turcz.) Drude 2n=28 = 12m +6sm+10st. The karyotypes of all the species
belong to “2A” except those of A. dailingensis and Coelopleurum saxatile, which belong to
“lA” and “2B” respectively. According to the karyotypic type and the presence or absence
of subterminal chromosomes, the karyotypes of 9 species reported in the present paper and
11 species previously reported can be divided into 3 groups. The scatter diagram (Fig. 2)
shows the karyotypic evolution of Angelica and related genera Coelopleurum with n = 14 and
karyotypic type “2B” is distinct from the related genera. Based on the fact that the kary-
otypes are not obviously different among Czernaevia, Archangelica and Angelica, Czernaevia
and Archangelica might botter be merged in Angelica as sections.
