Abstract
In seven species of Korean Asarum, 44 qualitative and 28 quantitative characters were reviewed taxonomically. Among 44 qualitative characters observed in vegetative and reproductive organs, the states of 27 characters were common in all the seven species. Among 28 quantitative characters, five characters have the same values in all the seven species; the number of cataphyll (2-4), leaf (2), calyx lobe (5), stamen (12) and pistil (6). White spots on adaxial surface of leaf (effectively) distinguished A. maculatum and A. versicolor from the other species. Many long soft hairs on abaxial surface of leaf distinguished A. mandshuricum from other species with short hairs. The glandular hairs on inner surface of calyx tube were divided into 2 types, reflecting the taxonomic relationships between the species: Type 1 has non-stalked glandular hairs (A. maculatum, A. sieboldii and A. sp.), and Type 2 has stalked glandular hairs (A. patens, A. versicolor, A. mandshuricum and A. misandrum). The length, shape, colour of calyx lobe and the extent to which the calyx lobe recurves, as well as the diameter and colour of calyx tube throat, were confirmed to be taxonomically valuable. In the case of glandular hair density on the surface of calyx lobe, A. patens with low density and A. sp. with high density were clearly distinct from all the other species with intermediate hair density. Meanwhile, the stylar protuberance length of A. patens (2.9-3.3 mm) was strikingly different from other species (1.4-2.5 mm). Additionally, further examination of the identities of A. yeonbyeonense and A. yeonbyeonense var. viridiluteolum is required.
