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.
