Acacia pinguifolia (sp. 80) has phyllodes 2-3 mm diam. and more longitudinal veins. Acacia barattensis (sp. 70) has flattened and longer phyllodes.

Taxonomic notes: A. menzelii is illustrated in colour in Kenny (1976).

Cultivation: Not known in cultivation but could be a useful ornamental shrub in lower rainfall areas.
