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.展开更多
