Juncaceae
The family Juncaceae (the rush family) is cosmopolitan and has seven genera and about 440 species. The rush family is found mainly in temperate to polar regions, and in the tropics it is found mostly above 2000 m elevation. Species of Juncaceae are grass-like herbs with glumaceous flowers that are usually bisexual, pentacyclic and trimerous. Here we present a taxonomic treatment of the species of Juncaceae that grow in Colombia, including 3 genera, 22 species and 3 infraspecific taxa. Keys for taxon identification, morphological descriptions, taxonomic notes, information regarding the geographic dis- tribution and distribution maps are provided, as well as, illustrations for the majority of Colombian Juncaceae.
