Description
Burmannia is a genus of mostly mycoheterotrophic plants, with ca. 61 accepted species found throughout the world, including 14 species in Thailand. Obtained from previous studies, it can be categorized into main two groups: Chlorophyllous and Achlorophyllous groups with and without chloroplasts, respectively. In this study we constructed a phylogenetic tree of 29 species, which included 12 species from Thailand, based on 18S rDNA and the internal transcribed spacer (ITS) regions using Bayesian, Maximum Likelihood, and Maximum Parsimony analyzes. Additionally, we also reconstructed the ancestral state of some interesting morphological characters, ie. the presence of rosette leaves, the presence of chloroplast, flower shapes, outer and inner perianth shapes.
