ous, it usually blooms later in the year and it has paler flowers than Acacia longifolia. It flowers usually from December through February. Some populations of Acacia obtusifolia can survive winters to -6C and possibly a light snow, however plants from populations in areas that are frost free such as the coastal ranges of Northern NSW are suscpetible to cold and will be killed by frosts lower than -3C. These populations avoid the valley floors and occur mainly on sandstone ridges well above the frost line.

Leucoanthocyanidin are colorless chemical compounds related to anthocyanidins and anthocyanins. Leucoanthocyanins can be found in Anadenanthera peregrina and in several species of Nepenthes including Nepenthes rajah, Nepenthes burbidgeae, Nepenthes tentaculata, Nepenthes × alisaputrana and...

, can be isolated from A. obtusifolia heartwood.

Net lore indicates a 0.45% average dimethyltryptamine in the bark and 0.3% in the dried young leaves. Similarly, Mulga states figures ranging from 0.4% to 0.5% in the dried bark, noting there to be some variability.
No formal scientific publishing of phytochemistry, several chromatographs show 0.3% alkaloid consisting 2:1 monomethyltryptamine,dimethyltryptamine,plus trace betacarbolines; another found additional 5methoxydimethyltryptamine and gramine. Is highly variable in composition, sometimes devoid of tryptamines (Ref: Nen in EntheogenReview (journal) 1996); privately commissioned test at Southern Cross University,NSW,Australia, 2000) Also findings of 5methoxyDMT, DMT & bufotenine
