Acacia macnuttiana, commonly known as McNutt's wattle, is a flowering plant in the family Fabaceae and is endemic to north-eastern New South Wales. It is a shrub with linear phyllodes, spherical heads of bright yellow flowers arranged in racemes in leaf axils and seeds usually in more or less straight, leathery pods.

Description

Acacia macnuttiana is a bushy shrub that typically grows to a height of {{cvt|1.5–3|m}} with finely ribbed, dark coloured branchlets. The phyllodes are narrow linear, {{cvt|80–150|mm}} long and {{cvt|2–3|mm}} wide, thin and glabrous. The flowers are arranged in a raceme {{cvt|10–50|mm}} long with more or less spherical heads of ten to fifteen bright yellow flowers, each head on a peduncle {{cvt|2–5|mm}} long. Flowering occurs between July and September and the pods are usually more or less straight, oblong to broadly linear, up to {{cvt|100|mm}} long, {{cvt|10–14|mm}} wide, dark brown and leathery, containing black seeds.{{Cite web |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Acacia~macnuttiana|title=Acacia mcnuttiana |last=Kodela |first=P.G. |date=2012 |website=PlantNet |access-date=2019-12-11}}

Taxonomy and naming

Acacia macnuttiana was first formally described in 1927 by Joseph Maiden and William Blakely in the Journal and Proceedings of the Royal Society of New South Wales from specimens collected in 1913 near the village of Bismuth near Torrington by [https://www.records.nsw.gov.au/image/15051_a047_006535 Andrew McNutt] who had been a schoolteacher at Hillgrove.

Distribution and habitat

McNutt's wattle grows near rivers and along valleys on sandy soils derived from granite from near Torrington to Boonoo Boonoo Falls, near Pindari Dam and the Washpool National Park, in north-eastern New South Wales.

Conservation status

This acacia is listed as "Vulnerable" under the Commonwealth EPBC Act, and "Endangered" under the Threatened Species Conservation Act of New South Wales.{{Cite web|url=http://www.environment.gov.au/biodiversity/threatened/species/pubs/10711-conservation-advice.pdf|title=Approved Conservation Advice for Acacia macnuttiana (McNutt's wattle) |date=2008 |website=Department of the Environment |location=Canberra |archive-url=|archive-date=|access-date=2019-12-12}}
