||The genus Liparis in Taiwan was taxonomically revised based on morphological, |
phytogeographical and ecological evidences. Pseudobulb articulation, leaf number, lip and column are the most valuable characters for the classification within the genus in Taiwan. The morphology of leaf epidermis and seed coat also provide useful information in subgenus or section level. Geographically, eleven species are distributed in Machilus-Castanopsis zone, in which the species L. somai Hayata, L. campylostalix Rchb. f., L. wrayi Hook. f., and L. henryi Rolfe have strict distributional range. According to cladistic analysis, the result reveals that Liparis is a paraphyletic group rather than a monophyletic group. As a result of above studies, twenty-two taxa, including one variety and two uncertain species, are recongnized. L. japonica (Miq.) Maxim. and L. cespitosa (Thouars) Lindl. are synonyms of L. elongata Fukuy. and L. laurisilvatica Fukuy., respectively. L. kawakamii Hayata and L. derchiensis Ying are instead conspecific to L. nakaharai Hayata. and L. japonica (Miq.) Maxim. L. amabilis Fukuy. and L. hensoaensis Kudo. are treated as uncertain species due to insufficiency of evidence.
