Geographical Distribution Patterns of the Apiaceae in Sakhalin and the Kuril lslands
Thirty species of the Apiaceae in Sakhalin (S) and the Kuril Islands (K) were examined on 1,592 specimens deposited in the main Japanese herbaria: KYO, SAPS, SAPT, TI and TNS. The geographical distribution of 27 of these 30 species was determined quantitatively. Ligusticum scoticum (number of specim...
