Colchicaceae is a family with a complicated distribution pattern.
Mannen J. Natalie F. Ehrendorfer 1994 Phylogeny of Rubiaceae-Rubieae inferred from the sequence of a cpDNA intergenic region.
Nordal I. Bingham 1998 Description of a new species, Gloriosa sessiliflora (Colchicaceae), with notes on the relationship between Gloriosa and Littonia.
A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented.
An investigation of the distribution of colchicine within the expanded Colchicaceae is conducted to evaluate the potential of colchicine as a synapomorphy of the re-circumscribed family.
Further, the DIVA analysis indicates that Colchicaceae originated in Australia, first reached Asia and North America, and later Africa, from where they expanded to Europe and also dispersed back to Australia.

Colchicaceae are cormose or rhizomatous geophytes that may be recognised by their rather large flowers with six free tepals, each more or less enveloping a stamen, and a superior ovary.
Stem group Colchicaceae are dated to ca 76 mybp, crown group Colchicaceae to ca 44 mybp (Janssen and Bremer 2004).
Although Colchicaceae are noted for their alkaloids, these are absent from these clades (including Uvularia: Kite et al.
The family includes approximately 225 ((biology) taxonomic group whose members can interbreed) species in 22 (Click link for more info and facts about genera) genera.

Conditions favoring the evolution of separate sexes (dioecy) in plants is one of the "big questions" of evolutionary biology.
The major limiting factor in microevolutionary studies of dioecy is the rarity of species containing a high degree of gender variation, such that recently-diverged sexual systems can be compared.
Australian Wurmbea dioica (Colchicaceae) is comprised of populations that are either monomorphic for gender, containing only cosexuals (hermaphrodites), or dimorphic for gender, containing separate sexes (males and females).

Our study demonstrates adverse effects of interference under natural conditions, and indicates that inappropriate pollen deposition may contribute to pollen limitation more often than previously recognized.
