CONDENSED tannins present in black wattle or commercial ‘mimosa’ extracts from the bark of Acacia mollissima show absorption behaviour (λmax. = 203 and 280 mµ) in the ultra-violet spectrum1, which is typical of the natural catechins and flavan-3.4-diols2 and also of their constituent phenols.

Multiplication of juvenile black wattle by microcuttings
Plant Cell, Tissue and Organ Culture, 2001The influence of mineral formulation, growth regulators and activated charcoal on micropropagation of juvenile black wattle (Acacia mearnsii) was studied. Nodal segments of one-month-old seedlings were used as starting material. After 30 to 45 days, they developed into shoots, which were divided into microcuttings and transferred to fresh media.

The Latin Name of the Black Wattle
Kew Bulletin, 1960The name A. decurrens var. mollis was published by Lindley in Bot. Reg. 5, t. 371 (1819), with a good description and plate. Mr. E. J. H. Corner kindly informs us that there is no specimen of this in the Lindley Herbarium at Cambridge University, nor has authentic material come to light elsewhere.

Southern Forests: a Journal of Forest Science
Black wattle (Acacia mearnsii De Wild.) stands as a pivotal commercial tree species, spanning 82 000 ha of land in South Africa. The revenue stream, sourced the from timber (85%) and bark (15%) sales, is estimated at US$200 million annually.

Black wattle tannin as a zinc phosphating coating sealer
Surface and Interface Analysis, 2013This paper reports an investigation into the use of condensed black wattle tannin as an environmental friendly sealer after zinc phosphating of carbon steel. In order to verify the sealer efficiency against corrosion, electrochemical impedance spectroscopy, potentiodynamic polarisation and salt spray tests were performed.
