A taxonomic study of KoreanSmilacina

Abstract

Several taxonomic problems of KoreanSmilacina were examined by statistical methods, based on morphological data. Consequently, S. davurica described in Korean flora differs greatly from original S. davurica, and closely related to S. bicoior morphologically. Therefore, the present authors treated this new taxon as a variety of S. bicolor, S. bicolor var. flavovirens N. S. Lee et J. Y. Kim vat. nov ("Yondusomdae" in Korean). The distribution in South Korea of S. bicolor var. bicolor is known as only Mt. Chiri, but this species is collected in Mt. Dukyou, also. The bounds of morphological variations of S. japonica var. japonica, the short plant size and no hairs on the stem, were revealed. The morphological characteristics of S. japonica var. japonica and S. japonica var. mandshurica is obscure to distinguish. According to the present study, S. japonica var. mandshurica differs from S. japonica var. japonica in plant size, size of adaxial leaf epidermal cell, ratio of style/ovary length and shape of stigma. The unrecorded taxon in Korean flora, S. robusta, was given a new Korean name as "Kunsomdae." Although S. japonica vat. mandshurica is the variety of S. japonica var. japonica, it is more closely related to S. robusta than to S.japonica var.japonica.
