Description

Acacia minniritchi is a shrub or tree that typically grows to a height of up to 4 m (13 ft) and has dark red Minni Ritchi bark. Its branchlets are angular with a few soft hairs on the ridges. The phyllodes are mostly 35–65 mm (1.4–2.6 in) long, 1–2 mm (0.039–0.079 in) wide, thinly textured, not rigid and have yellowish hairs that lie flat on the surface. There are many veins, the central vein most prominent, and a gland 0.4–3 mm (0.016–0.118 in) above the pulvinus. The flowers are bright yellow and borne in spikes 20–40 mm (0.79–1.57 in) long. Flowering occurs between May and July and the pods are linear, 40–90 mm (1.6–3.5 in) long, 4–5 mm (0.16–0.20 in) wide, greenish brown, sticky, and covered with shaggy hairs, especially when young. The seeds are oblong, compressed and brown to black. [2] [3] [4]

Taxonomy

In 1975, Mary Tindale describe Acacia gracillima in the journal Telopea from specimens collected on Bold Bluff by William Vincent Fitzgerald in the Western Kimberley in 1905, but that name was illegitimate because it had already been given to a fossil species by de Saporta. [5] [6] In 2014, Ian Mark Turner changed the name to Acacia minniritchi in Annales Botanici Fennici . [7]

Distribution and habitat

Acacia minniritchi grows in grassland or on steep, rocky slopes, often amongst quartzite, from the Buccaneer Archipelago and south east to the King Leopold Range in the Central Kimberley, Dampierland and Northern Kimberley bioregions of northern Western Australia. [2] [4]
