''Cymbonotus lawsonianus'', commonly known as bear's ears, is a species of small shrub in the daisy family from southeastern Australia. It has been described as ''Arctotis lawsoniana''. It is one of three species in the small genus ''Cymbonotus''.〔 It was named in honour of the explorer William Lawson. ''Cymbonotus lawsonianus'' is a herbaceous perennial which may reach 30 cm (12 in) high, its leaves arranged in a rosette pattern on the ground. The leaves themselves are ovate, lanceolate or elliptic, and measure anywhere from 2 to 25 cm (0.8–10 in) long, 2–9 cm (0.8-3.6 in) wide, with margins entire or toothed. The yellow flowers occur from autumn to spring (March to October), and are pollinated by insects. They are followed by small black seeds in early spring (September and October). It is found from Toowoomba and the Darling Downs in south-eastern Queensland southwards throughout New South Wales, and into northern Victoria, southeastern South Australia and Tasmania.〔 It grows on both clay and sandstone soils and various loams in between, often in forest or open woodland. It can also be found in parks and gardens.〔 Molecular studies of African genera and ''C. lawsonianus'' showed the plant to be very closely related to the genera ''Arctotis'' and ''Haplocarpha'', suggesting they must have been dispersed across the Indian Ocean to Australia somehow. It is adaptable to the home garden and grows in a variety of soils, although does not tolerate waterlogging. It is a good rockery plant. Early settlers mixed the plant in lard and used as a wound salve.〔 ==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「Cymbonotus lawsonianus」の詳細全文を読む スポンサード リンク
