Abstract: The present paper reports karyotypes in 4 species and 5 subspecies of Hippophae L. in China. It is found that all of the species and subspecies are diploid, with 2n=24, their com- plements are made of m and sm chromosomes and of them only H. thibetana has a pair of satel- lites. All of these karyotypes are symmetrical and primitive. It can be simplied as follows: Hippophae neurocarpa 2n = 2x = 24 = 18m+6sm, H. thibetana 2n = 2x = 24 = 14m (2sat)+ 8sm, H. rhamnoides L. ssp. gyantsensis 2n=2x=24= 18m+ 6sm, H. salicifolia 2n = 2x = 24 = 10m + 14sm, H. rhamnoides L. ssp. sinensis 2n=2x= 24 = 18m + 6sm, H. rhamnoides L. ssp. turkestanica 2n = 2x = 24 = 20m + 4sm; Hi. rhamnoides L. ssp. yunnanensis 2n = 2x = 24 = 14 + 10sm, H. rhamnoides L. ssp. mongolica 2n = 2x = 24 = 16m + 8sm.
