Uvulariaceae
Encyclopedia
Uvulariaceae is a botanical name
of a family of flowering plants. While seldom recognised, the family is accepted by the Dahlgren system
, which places it in order Liliales
, superorder Lilianae
, and the subclass Liliidae
[=monocotyledons] of class Magnoliopsida
[=angiosperms].
The APG II system
places the genus Uvularia
in family Colchicaceae
, which is assigned to order Liliales
in the clade monocots.
Molecular studies have shown that Uvulariaceae is polyphyletic, meaning that the genera
placed in the family have closer relationships with other plants than with each other. The family have been split and the genera Disporum
, Kuntheria, Schelhammera
, Tripladenia
and Uvularia
are now placed in the autumn crocus family (Colchicaceae
), while Clintonia
, Medeola, Prosartes
, Scoliopus
and Streptopus are placed in the lily family (Liliaceae
). The genus Kreysigia has a somewhat troublesome taxonomic history and is either synonymous to Tripladenia
or Schelhammera
(which, together with Kuntheria should perhaps all be treated as Schelhammera).
