Pitcairnia subg. Pepinia is a subgenus of plants in the family Bromeliaceae. It has at times been treated as the separate genus Pepinia, but is now included again in the genus Pitcairnia. The name is for Pierre Denis Pépin, French member of the Imperial and Central Society of Agriculture (c.1802-1876).[1]
Pepinia was established as a genus in 1870 by Adolphe-Théodore Brongniart in a publication by Édouard André. Pepinia was reduced to a subgenus of Pitcairnia in 1881 by John Gilbert Baker, but elevated again to a genus in 1988, largely on the basis of the morphology of its seeds. The use of morphological characters to differentiate Pepinia from Pitcairnia was rejected in 1999; a view later confirmed by multiple molecular studies.
