Notes on Phylogeny of the Genus Micropera Lindl. (Orchidaceae) in Thailand

EasyChair Preprint 9660

Abstract

The genus Micropera Lindl. belongs to the family Orchidaceae. It is one of the uncertainty monophyletic groups. Since the previous phylogenetic analysis employed only one species, more species are needed to reveal whether this genus forms a monophyletic group or not. Thus, this study was conducted to construct the phylogeny for the genus Micropera based on molecular data by adding 4 Thai Micropera taxa. The phylogenetic analysis was performed by using matK, ITS and combined both genes, with selected taxa in Trichoglottis clade as outgroups. It was shown that Micropera is a monophyletic group and should be accepted genus. The twist rostellum is a taxonomic character for grouping among 4 Thai Micropera species. All taxa of the genus are required for revealing the evolution relationship of this genus.

Keyphrases: Micropera, Orchidaceae, molecular phylogeny, monophyletic group
