''Rosa canina'', commonly known as the dog-rose, is a variable climbing wild rose species native to Europe, northwest Africa and western Asia. It is a deciduous shrub normally ranging in height from 1–5 m, though sometimes it can scramble higher into the crowns of taller trees. Its stems are covered with small, sharp, hooked prickles, which aid it in climbing. The leaves are pinnate, with 5-7 leaflets. The flowers are usually pale pink, but can vary between a deep pink and white. They are 4–6 cm diameter with five petals, and mature into an oval 1.5–2 cm red-orange fruit, or hip. ==Synonyms== From DNA analysis using amplified fragment length polymorphisms of wild-rose samples from a transect across Europe (900 samples from section ''Caninae'', and 200 from other sections), it has been suggested that the following named species are best considered as part of a single ''Rosa canina'' species complex, and are therefore synonyms of ''R. canina'': * ''R. balsamica'' Besser * ''R. caesia'' Sm. * ''R. corymbifera'' Borkh. * ''R. dumalis'' Bechst. * ''R. montana'' Chaix * ''R. stylosa'' Desv. * ''R. subcanina'' (Christ) Vuk. * ''R. subcollina'' (Christ) Vuk. * ''R. × ''irregularis'' Déségl. & Guillon 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「Rosa canina」の詳細全文を読む スポンサード リンク
