1.The karyotypes of five species and three varieties in Ranunculus are determined as follows:
R. japonicus K(2n)=14=2A1m+2A2m+2Bm+2C1st+22Cst+2C3st+2tDst
R. yakushimensis K(2n)=14=2A1m+2A2m+2Bm+2C1st+2C2st+2C3st+2tDst
R. auricomus K(2n)=28=4A1m+4A2m+4Bm+4C1st+4C2st+4C3st+4tDst
R. ternatus var. glaber K(2n)=16=2A1m+2A2sm+2A3sm+2B1st
+2B2st+2Bst+2Cst+2Dst
R. ternatus var.
quelpaertensis K(2n)=16=2A1m+2A2sm+2A3sm+2B1st
+2B2st+2B3st+2Cst+2Dst
R. cantoniensis K(2n)=32=4A1m+4A2sm+4A3sm+4B1st
+4B2st+4B3st+4Cst+4Dst
R. sceleratus K(2n)=32=12Am+4Bm+12Cst+4Dst
R. reptans var. flagellifolius K(2n)=32=12Am+4Bsm+16Cst
2. Comparing the 7-basic complement in fig. 1 with the 8-basic one in fig. 3, we find the former to differ markedly from the latter in the absence of a chromosome corresponding to h in fig. 3 and the presence of a satellite g in fig. 1.
3. From the karyotype analysis, the race with the basic number 8 is divided into two groups. The first includes R. cantoniensis and the two varieties of R. ternatus, and the second R. sceleratus and R. reptans var. flagellifolius.
