''Pycnosorus'' is a genus of Australian plants in the pussy's-toes tribe within the daisy family.〔Bentham, George. 1837. Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel page 63〕〔(Tropicos, Pycnosorus Benth. )〕 ''Pycnosorus'' grow in wetter conditions everywhere from sea level to the alps. The genus is found in every state of Australia, except Western Australia. The leaves form rosettes and are usually linear. They range in colour from white through to grass green, and are usually covered in fine hairs. The flowers are hemispherical to spherical and are formed of tiny flowers (florets) without any surrounding ligules. ;Species〔(Flann, C (ed) 2009+ Global Compositae Checklist )〕〔(Atlas of Living Australia )〕 == Cultivation == ''Pycnosorus globosa'' is a commonly grown cut flower, and is exported to the world from wild collection from around the Murray river. The tall flower stalks, with their yellow spikey spherical heads are very popular, particularly in Japan. ''Pycnosorus'' can be propagated by division by cutting a rosette from a clump or by seed. Seeds from temperate varieties will germinate in days if lightly sprinkled on seed raising media and not covered. Plants are generally only poorly self-fertile. In the wild they grow in very poor soils that are seasonally inundated. In cultivation they appreciate good potting mix, including Phosphorus. Most species are widely grown both as ornamentals and for revegetation work. 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「Pycnosorus」の詳細全文を読む スポンサード リンク
