Mostly tropical and subtropical, worldwide.
Genera ca. 15, species ca. 125 (3 genera, 5 species in the flora).
Although Burmanniaceae have traditionally been placed in the Orchidales, it has been suggested that the family may be more closely related to the Melanthiales (= Liliales in the broad sense, as traditionally circumscribed) (R. M. T. Dahlgren et al. 1985). More recently, molecular and morphological studies by L. R. Caddick et al. (2000, 2000b) support placement of the family in the Dioscoreales.
Burmanniaceae traditionally have been characterized as saprophytic, but the life form is more accurately described as mycotrophic or myco-heterotrophic (J. R. Leake 1994). Even the photosynthetic species have been shown to be endomycorrhizal (P. J. M. Maas et al. 1986b; C. E. Wood Jr. 1983) and have been described as hemisaprophytic. Saprophytism in the Burmanniaceae and other achlorophyllous families has been fully discussed by J. R. Leake (1994).
