Description

Philotheca myoporoides subsp. acuta is a shrub that typically grows to a height of 1.8–2 m (5 ft 11 in – 6 ft 7 in) with glabrous, densely glandular-warty stems. The leaves are sessile, oblong-elliptic to elliptic or rarely lance-shaped with the narrower end towards the base, 25–40 mm (0.98–1.57 in) long and 4–8 mm (0.16–0.31 in) wide and there is a small point on the tip. The flowers are arranged singly or in twos or threes in leaf axils on a peduncle up to 5 mm (0.20 in) long, each flower on a pedicel 1–10 mm (0.039–0.394 in) long. The petals are broadly elliptic, about 8 mm (0.31 in) long with a prominent keel. Flowering mainly occurs in spring and autumn.[2][3][4]

Taxonomy and naming

This taxon was first formally described in 1941 by William Blakely who gave it the Eriostemon myoporoides var. acutus and published the description in Contributions from the New South Wales Herbarium.[5] In 1998, Michael James Bayly changed the name to Philotheca myoporoides subsp. acuta in the journal Muelleria.[6]

Distribution and habitat

This subspecies grows on rocky sandstone hills, mainly from Lockhart to south of Cobar in southern central New South Wales.[3][2]
