Phylogenetic reconstruction of Burmannia L. (Burmanniaceae): a preliminary study

ZHANG Dian-Xiang

Abstract:

Preliminary cladistic analyses of the genus Burmannia were performed using different

outgroups. Although results from different analyses were inconsistent in some aspects, some clades

were found in both analyses, suggesting the specific relationships among species in these clades are

well-solved. Of the two sections recognized by Jonker, sect. Foliosa is probably a monophyletic

group, while sect. Burmannia is not. If the loss of chlorophyll is considered to be an irreversible

process, holo-mycoheterotrophism has very likely emerged only once in the tribe Burmannieae.

Key words: Burmannia, Burmanniaceae, Cladistic analysis, Mycoheterotroph, Mycoheterotro-
