The genus Daubenya is indigenous to the winter rainfall regions of the Western Cape, South Africa. Its species are all very local, uncommon to exceedingly rare, and found in a narrow swath of land across the Western Cape.
The genus Daubenya was revised in 2002 by John Manning and Alison van der Merwe. Several formerly monotypic genera of closely related bulbs were merged into Daubenya at that time.
The genus Daubenya now comprises the following species:
comata (Burch. ex Baker) J.C. Manning & A.M. van der Merwe
Formerly Massonia comata Burch. ex Baker, Polyxena comata (Burch. ex Baker), Neobakeria comata (Burch. ex Baker)
namaquensis (Schltr.) J.C. Manning & A.M. van der Merwe
Formerly Neobakeria namaquensis Schltr., Massonia angustifolia sensu Jessop
marginata (Willd. ex Knuth) J.C. Manning & A.M. van der Merwe
Formerly Massonia marginata Willd. ex Knuth, Marginata rugulosa Licht. ex Knuth, Polyxena haemanthoides Baker
capensis (Schltr.) A.M. van der Merwe & J.C. Manning
Formerly Androsiphon capense
stylosa (W.F.Barker) A.M. van der Merwe & J.C. Manning
Formerly Amphisiphon stylosum
