• Type: " "Black Wattle." Tree good for tan bark. Up to about thirty feet high. Milton (R.H. Cambage, No. 784, December, 1902; No. 4113; November, 1914; No. 4151, August, 1915). ... I constitute the Milton specimens type of the new species."

taxonomic synonym: Acacia penninervis var. angustifolia Maiden legitimate

• Etymology: "... the new species... is named in honor of my young friend Miss Mabel Fanny Cambage. The naming of a wattle after her is appropriate, because she is Honorary Treasurer of the New South Wales Branch of the Wattle Day League in connection with which she has done admirable service, and this particular wattle has associations for her in that many specimens occur on the South Coast property of her grand parents."
• Comment: The epithet is treated here as being based on the Latin name Mabella rather than its English equivalent, Mabel.

• Text: "Mabel Fanny Cambage (1883–1939) was a daughter of R.H. Cambage (1859–1929), a botanical colleague of J.H. Maiden. Since Maiden consistently used the form mabellae, it must be accepted that he deliberately adopted a latinisation of Miss Cambage's name as Mabella. A change to mabelliae is not in accordance with International Code of Botanical Nomenclature, and mabeliae would not be justified in light of Maiden's deliberate modification of the name."
