''Hedraianthera'' is a genus of a sole recognised species of shrubs or small trees found only in Australia. The genus and species constitutes part of the Bittersweet plant family Celastraceae.〔〔 The species ''Hedraianthera porphyropetala'' grows naturally in eastern Australia in littoral or sub-tropical rainforest north from Ballina, New South Wales to Cooktown in tropical north eastern Queensland. They grow in gullies or rocky slopes on shallow soils, sometimes enhanced by basalt.〔〔〔 The generic name ''Hedraianthera'' is from Greek, it refers to the flower anthers without stalks. The specific epithet ''porphyropetala'' is also from Greek, it alludes to the attractive deep purple coloured flowers, although the species definition includes plants which have different coloured flowers such as green. They are an unusually southern example of ramiflory. Previously several publications provided informal scientific descriptions of another species under the provisional scientific name ''Hedraianthera'' sp. Mossman (V.K.Moriarty 2557) Qld Herbarium.〔〔〔 In a 2012 published Celastraceae genetics study this provisionally named species was reassigned to the genus ''Brassiantha'' and formally scientifically described under the new name ''Brassiantha hedraiantheroides'', after its likeness to ''Hedraianthera''.〔〔 Though still relatively closely related the two species were found to be constitutive of different genera. ''H. porphyropetala'' here, again became the only known species in this genus and now ''Brassiantha'' constituted not only by the one, but instead by only the two known species, this forementioned ''B. hedraiantheroides'' and the New Guinean ''B. pentamera''. ''B. hedraiantheroides'' grows naturally only (endemic) in a restricted area of the wet tropics region of north eastern Queensland, Australia. It grows as an understory shrub or small tree in rainforests and sclerophyll forests, from an altitudinal range near sea level to .〔〔 ==References== 〕 }} 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「Hedraianthera」の詳細全文を読む スポンサード リンク
