Pitcairnioideae: Difference between revisions

'''Pitcairnioideae''' is a subfamily of the bromeliad family, [[Bromeliaceae]]. Traditionally, it was a large subfamily, comprising all those species with winged or more rarely naked seeds. [[Molecular phylogenetics|Molecular phylogenetic]] studies showed that traditional Pitcairnioideae was not [[Monophyly|monophyletic]], and the subfamily was more narrowly [[Circumscription (taxonomy)|circumscribed]].<ref name=GivnMillBerrSyts07/><ref name=GivnBarfVanERiin11/> {{As of|2022|November}}, the Encyclopaedia of Bromeliads placed five genera in the subfamily.<ref name=EOB/> Members of the subfamily are found from the [[Andes]] to the coast of [[Brazil]], with one genus (''[[Fosterella]]'') found northwards to [[Mexico]].

Species in the subfamily Pitcairnioideae have fruits in the form of capsules andwith winged seeds. The [[petal]]s are not joined together when the flowers open, and are usually large and conspicuous.<ref name=GivnMillBerrSyts07/>

Traditionally, the family Bromeliaceae was divided into three subfamilies based on the structure of the seeds and fruit, with Pitcairnioideae comprising all those with winged or rarely naked seeds. The other subfamilies were [[Bromelioideae]] and [[Tillandsioideae]]. A [[Molecular phylogenetics|molecular phylogenetic]] study in 2007 showed that traditional Pitcairnioideae was not [[Monophyly|monophyletic]], with Tillandsioideae embedded within it. The original broadly defined subfamily was divided it into six, including a more narrowly [[Circumscription (taxonomy)|circumscribed]] Pitcairnioideae.<ref name=GivnMillBerrSyts07/> The division was confirmed in a larger 2011 study,<ref name=GivnBarfVanERiin11/> and is accepted by the Encyclopaedia of Bromeliads, which includes five genera in Pitcairnioideae.<ref name=EOB/>

The subfamily is thought to have arisen in the northern [[Andes]], first spreading southwards and then eastwards into the [[Brazilian Shield]] and the easternmost part of [[Brazil]] (the "horn of Brazil"). ''Fosterella'' is also found in Mexico and Central America.<ref name=GivnBarfVanERiin11/>
