Tall, glabrous, spreading shrubs 1-3 m high; branches spreading almost terete; bark smooth reddish-brown.

Inflorescences in axillary racemes usually shorter than phyllodes, consisting of 4-16 heads, often appearing paniculate towards the ends of the-branches; flower-heads globular, deep yellow, c. 50-flowered; peduncles glabrous, short and thick; flowers 5-merous.

Legumes narrowly oblong, 3-7 cm long, c. 10 mm broad, straight, flat but raised over seeds; margins thickened vein-like. Seeds transverse in legume; funicle long, encircling the seed in a double fold.

Related taxa: Acacia validinervia was previously regarded as a variety of A. notabilis. It differs mainly in the prominent lateral reticulate venation of the phyllodes. Acacia beckleri is closely allied but distinguished by its longer narrower phyllodes and larger flower-heads. Acacia pruinocarpa has similar phyllodes but differs in its inflorescences with sparsely arranged flower-heads on long peduncles.

A possible hybrid hetween A. notabilis and A. anceps occurs only in a small population in the hundred of Glynn on Eyre Peninsula.

Taxonomic notes: Some comments on A. notabilis and its relationships to A. anceps may be found in Maslin & Whibley (1987).

Cheal (1981) describes the relatively recent (1979) recognition of A. notabilis in the far north-west of Victoria. A description is given to distinguish it from other local species.

The only mistletoe found on Acacia notabilis has been a single collection of Amyema preissii.

A. notabilis is reported by Isaacs (1987) to be a source of both gum and seeds for Aboriginal food.

Cultivation: A handsome, bushy, blue-green shrub with large deep, yellow flowers in the spring. Suitable as an ornamental and also as a low shelter belt species in dry inland areas.
