A stringybark can be any of the many ''Eucalyptus'' species which have thick, fibrous bark. Like all eucalypts, stringybarks belong to the family Myrtaceae. In exceptionally fertile locations some stringybark species (in particular messmate stringybark (''Eucalyptus obliqua'') can be very large, reaching over 80 metres in height. More typically, stringybarks are medium-sized trees in the 10 to 40 metre range. Early European colonists often used the bark for roofing and walls of huts. The term ''stringybark'' is a descriptive, vernacular name and does not imply any special taxonomic relationship within the genus ''Eucalyptus''. For example, scientists consider ''Eucalyptus obliqua'' to not be closely related to the other stringybarks, because of the gumnut shape.〔Forest Trees of Australia, D.J. Boland et al. 1992 ISBN 0-909605-57-2 page 302〕 And ''Eucalyptus acmenoides'' is part of the ''mahogany'' group of eucalyptus. Also as the gumnuts are a different shape, despite the bark being somewhat stringy.〔Forest Trees of Australia, D.J. Boland et al. 1992 ISBN 0-909605-57-2 page 270〕 There are many different species of stringybark, including: * Blue-leaved stringybark (''Eucalyptus agglomerata'') * Brown stringybark (''Eucalyptus baxteri, Eucalyptus laevopinea'') * Mealy stringybark (''Eucalyptus cephalocarpa'') * Messmate stringybark (''Eucalyptus obliqua'') * Privet-leaved stringybark (''Eucalyptus ligustrina'') * Red stringybark (''Eucalyptus macrorhyncha'') * Tindale's stringybark (''Eucalyptus tindaliae'') * Yellow stringybark (''Eucalyptus acmenoides'', ''Eucalyptus muelleriana'', ''Eucalyptus umbra'') * Thin-leaved stringybark (''Eucalyptus eugenioides'') * White stringybark (''Eucalyptus globoidea'') * Wollemi stringybark (''Eucalyptus expressa'') * Stringybark or narrow-leaved stringybark (''Eucalyptus oblonga'') * Stringybark (''Eucalyptus tenella'') Studies have shown that blue-leaved stringybark is one of the 20-odd eucalypts preferred by koalas. == 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「stringybark」の詳細全文を読む スポンサード リンク
