Native trees and shrubs of south-eastern Australia, p. 161.) Spiny-leaved shrub 0.5-2 m high; branchlets appressed-pubescent, tardily glabrescent, older branchlets with a prominent glabrous rib decurrent from each leaf base for several nodes; leaves (in S. Aust.) widely spreading, dense, rigid, linear, 0.6-3.1 cm X 0.7-1 mm, soon glabrescent, upper side with 2 lateral veins and a mid-vein often divided into 3 veins, lower side with 2 persistently sericeous narrow grooves between the recurved margins and midrib, mucro long, straight, sharp.

Racemes simple, terminal on branchlets or on short axillary shoots, umbelliform, with 7-16 flowers; rhachis 0.5-2.2 mm long, brown-tomentose; pedicel and perianth externally sparsely white-sericeous; pedicel 2.6-6.5 mm long, slender, pink; torus slightly oblique; perianth 2.6-4 mm long, narrow, pale-pink or white, white-hirsute inside around the ovary, strongly recurved below the transverse-ovoid limb, splitting into 4 free segments; gland small, semi-annular; pistil glabrous, the stipe twice the length of the ovary; style recurved, 5.5-7 mm long (straightened), white, exserted well above the perianth; pollen-presenter an oblique concave disc with scattered tiny papillae below and a short broad central cone above.

Fruit slightly curved-ellipsoid, 12-13 mm long, smooth, blackish, vertically inserted on a long slender stipe, with a usually persistent terminal curved style, glabrous; young seed compressed, broadly elliptic, grooved longitudinally on one side, with a blunt apical caruncle-like body.

Taxonomic notes: Material from Vic. and N.S.W. (var. parviflora) diverges only in its less rigid leaves more broadly grooved below and with only 3 longitudinal veins (a single mid-vein and two along the edge) above. Materal from S. Aust.: EP, KI can usefully be separated as var. acuaria F. Muell., but the above venation characters sometimes occur. There seems no basis for a distinct S. Aust. species.
