''Prostanthera stenophylla'' is a shrub species that is endemic to Wollemi National Park in New South Wales, Australia. It grows to between high and has leaves that are long and wide. Dull green above and paler green below, leaves are covered with a dense mat of hairs and give off a strong aroma when crushed. The leaf edges are recurved or revolute.〔 Mauve or violet flowers appear in the leaf axils in spring, with about 4 to 6 flower-bearing branchlets arising on a leafy branch to form a raceme.〔 Individual flowers are about long.〔 The species was first formally described by Barry Conn of the New South Wales Herbarium in the journal ''Telopea'' in 2006. He held it to be allied to the granite mintbush (''Prostanthera granitica''), within the genus. The latter species is similar in appearance but has stiffer rougher hairs and broader leaves.〔 ''Prostanthera stenophylla'' is found in sclerophyll forest dominated by black cypress pine (''Callitris endlicheri''), snappy gum (''Eucalyptus rossii'') and Sydney peppermint (''E. piperita''), where it arises in sandstone outcrops,〔 which are colloquially known as 'pagodas'.〔 The first recorded collection of plant material from the type locality was by nurseryman George Althofer in 1952. A 1937 collection by Lindsay Pryor is recognised as this species, but the given locality of "Canberra district" is believed to be incorrect.〔 The specific epithet ''stenophylla'' is a combination of the Greek words ''steno'' (narrow) and ''phylla'' (leaves).〔 The species has been in limited cultivation for some years. The unofficial name of ''Prostanthera rylstonii'' has been used by plant nurseries since at least 2005.〔 ==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「Prostanthera stenophylla」の詳細全文を読む スポンサード リンク
