Globba, the largest genus of Globbeae with 90 species, is the subject of monographic and pollination biology studies in addition to the current study. The genera of Globbeae (Gagnepainia, Globba, Hemiorchis, and Mantisia) are distinguished from the rest of the family by the possession of a unilocular ovary with parietal placentation. In order to elucidate the relationships within Globba and the Globbeae a phylogenetic analysis using the ITS region was conducted on a broad sampling of the tribe. Parsimony analysis supports two pairs of sister genera: Globba + Mantisia and Gagnepainia + Hemiorchis. These data support the monophyly of the sections of Globba which are based upon the number of anther appendages (0,2, or 4).
