| The morphology and somatic chromosome numbers of Korean Parasenecio were investigated to estimate their taxonomic values. Some morphological characters, such as the length of whole plants, the numbers of cauline leaves, the shapes of leaf and petioles, the numbers of involucral bracts, floret numbers per head, presence of trichomes on the style, ratio between wide part and narrow part of floret and the size of achene were found to be a good characters for delimiting each taxa. Based upon these characters, six taxa, Parasenecio auriculala var. auriculata, P. auriculata var. kamtschatica, P. hastata subsp. orientalis, P. koraiensis, P. firmus, P. pseudotaimingasa, were recognized about their distribution in Korea, but 2 taxa, P. adenostyloides, P. auriculata var. matsumurana, were needed to be studied their taxonomic position and distribution in Korea. The somatic chromosome numbers of six taxa, P. adenostyloides, P. auriculata, P. auriculata var. kamtschatica, P. hastata subsp. orientalis, P. firmus, P. pseudotaimingasa were 2n=60 and those of P. firmus and P. pseudotaimingasa were reported first in this study. |
