Abstract
Fritillaria tokushimensis(Liliaceae)was described as new species by Naito(2005). Fritillaria shikokiana and F . muraiana which distribute in the same area, Shikoku Island, are closely related to the new species. These 3 taxa belonging to F . japonica group, resemble morphologically closely and show their differences only in flower. Comparing the new species with the othe two, F . shikokiana and F . muraiana, we conclude that the new plant is a natural hybrid between them, because of many intermediate characters among the numerous morphological characters of their flowers. Namely shape of flower, shape and pattern of outer and inner perianth, process on style and filament are intermediate character. Moreover, 13 of the 33 morphological characters of flower meas-ured in the present study are in intermediate values. Hybrid nature of the plant is also discussed from the point of chromosome number and karyotype, geographical distribution and habitat.
