''Poranthera'' is a genus of flowering plant belonging to the family Phyllanthaceae first described as a genus in 1811.〔(Rudge, Edward. 1811. Transactions of the Linnean Society of London 10: 302-303 ) in Latin〕〔(Tropicos, ''Poranthera'' Rudge )〕 It is one of eight genera in the tribe Poranthereae.〔Maria S. Vorontsova and Petra Hoffmann. 2008. "A phylogenetic classification of tribe Poranthereae (Phyllanthaceae)." ''Kew Bulletin'' 63(1):41-59.〕 Its closest relative is ''Pseudophyllanthus''. ''Poranthera'' is native to Australia and New Zealand.〔(Kew World Checklist of Selected Plant Families )〕 The name is a hybrid, derived from the Greek word, ''poros'', "opening or pore", and the Latin word ''anthera'', "anther".〔〔Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names''. volume III,. CRC Press: Baton Rouge, New York, Washington DC, USA; London, England. ISBN 978-0-8493-2677-6 (vol III). (see ''External links'' below)〕 ''Poranthera'' consists of monoecious or rarely, dioecious annual or perennial herbs. On the anthers, the line of dehiscence does not extend beyond the apex. It does not have the clearly round pores that define truly poricidal dehiscence.〔 ''Poranthera alpina'' has been placed in the monospecific genus ''Oreoporanthera'' by some authors, but in 2007, a molecular phylogenetic analysis of matK and ITS sequences showed this species to be embedded in ''Poranthera''.〔Maria S. Vorontsova, Petra Hoffmann, Olivier Maurin, and Mark W. Chase. 2007. "Phylogenetics of tribe Poranthereae (Phyllanthaceae)." ''American Journal of Botany'' 94(12):2026-2040.〕 ;Species〔 ;names in Poaceae〔 In 1830, Rafinesque〔Rafinesque, Constantine Samuel. 1830. Bulletin Botanique () 1: 221〕 used the name ''Poranthera'' to refer to a very different plant than that to which Rudge had already applied the name. Thus he created an illegitimate homonym. Species names coined using Rafinesque's homonym:〔(Tropicos, ''Poranthera'' Raf. )〕〔(The Plant List, synonymy for ''Sorghastrum nutans'' (L.)
