| Abstract: | In this paper, chromosome numbers and karyotypes are reported for 12 species of Aconitum L. and three species of Delphinium L. from China. The results are as follows: A. scaposum var. scaposum and A, scaposum var. vaginatum 2n=16 = 2m 6sm 8st; A. albovi-olaceum 2n = 16 = 2m 6sm ( 2sat) 8st; A. sinomontanum var. sinomontanum 2n = 16 = 4m 4sm 8st; A. sinomontanum var'. angustius 2n = 32 = 6m4-6sm 20st(lsat) ; A.brunneum 2n=16 = 2m(lsat) 14sm; A. sungpanense 2n = 16 = 6m(2sat) 10sm(2sat) ; A. arcuatum 2n = 16 = 4m 12sm; A. carmichaeli 2n=32 = 10m 22sm; A. kusnezoffii 2n=32 = 10m 22sm; A. jaluense 2n = 32 = 10m 22sm; A. flavum 2n = 16 = 2m 14sm; A. pendulum 2n = 16 = 4m 12sm; A. sessiliflorum 2n = 16 = 2m lOsm 4st; D. kamaoense var. glabrescens 2n = 16 = 2m 6sm 8st; D. caeruleum 2n = 16 = 2m 6sm 8st D. maximauj-iczii 2n = 16 = 2m 6sm 8st. The chromosome numbers and karyotypes of A. scaposum var. scaposum A. sinomontanum var. angustius A. brunneum A, gungpanense A, jaluense A. flavum A. sessiliflorum D. kamaoense var. glabrescens D. caeruleum and D. maxtmowiczii are reported here for the first time. |
