''Meineckia'' is a genus of flowering plants in the family Phyllanthaceae first described as a genus in 1858.〔Baillon, Henri Ernest. 1858. Étude générale du groupe des Euphorbiacées 586〕〔(Tropicos, ''Meineckia'' Baill. )〕 ''Meineckia'' 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. 〕 They are native to the Americas, South Asia, Africa, and Madagascar.〔(Kew World Checklist of Selected Plant Families )〕 The genus is particularly well represented in Madagascar. Species of ''Meineckia'' may be monoecious or dioecious. They are trees or shrubs, or rarely, they are subherbaceous. ;Species〔 ==Circumscription== The circumscription of ''Meineckia'' has undergone several changes since Henri Ernest Baillon erected the genus in 1858. 〔 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. 〕 Some of its species have been put in other genera and sometimes other genera have been merged with it. The name ''Peltandra'' had been used for some species in ''Meineckia'', 〔 ''Peltandra'' At: International Plant Names Index (see ''External links'' below). 〕 but this is now a nomen rejectum. The name ''Peltandra'' is now conserved as the name of a genus in Araceae. 〔''Peltandra'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below).〕 ''Meineckia'' was last revised in 2008 by Vorontsova and Hoffmann. They recognized 30 species and divided the genus into two subgenera. 〔 ''Meineckia'' subgenus Petaliferae has only two species: its type species, ''Meineckia cerebroides'', and ''Meineckia gracilipes''. They are dioecious shrubs from Madagascar. Their petals are very small. ''Meineckia'' subgenus Meineckia has 28 species. Its type species, ''Meineckia phyllanthoides'', is the same as that of the genus. 〔 ''Meineckia'' At: Index Nominum Genericorum. (see ''External links'' below). 〕 They are monoecious or dioecious trees or shrubs, or sometimes, subherbaceous. Their flowers have no petals. This subgenus is the only completely apetalous taxon in the tribe Poranthereae. Vorontsova and Hoffmann did not recognize ''Zimmermannia'' and ''Zimmermanniopsis'' as separate genera, but placed their species in ''Meineckia'' subgenus Meineckia. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Meineckia」の詳細全文を読む スポンサード リンク
