Acacia obtusifolia, commonly known as stiff-leaf wattle or blunt-leaf wattle, is a perennial tree in subfamily Mimosoideae of family Fabaceae.
Description
Acacia obtusifolia is an upright or spreading perennial tree, which grows from 1.5m to 8m in height and is native to Australia. It is closely related to Acacia longifolia. A. obtusifolia can be distinguished by having phyllode margins which are resinous, usually blooming later in the year and with paler flowers than A. longifolia.[2] It flowers usually from December through February. Some populations of A. obtusifolia can survive winters to −6 °C and possibly a light snow; however, plants from populations in areas that are frost-free such as the coastal ranges of Northern NSW are susceptible to cold and will be killed by frosts lower than −3 °C. These populations avoid the valley floors and occur mainly on sandstone ridges well above the frost line.
Phytochemicals
Teracacidin, a flavan-3,4-diol, can be isolated from A. obtusifolia heartwood.[3]
Despite the lack of formal scientific publishing of its phytochemistry, several chromatographs show 0.3% alkaloid consisting of 2:1
