Type: New South Wales: Northern Tablelands: high part of Bolivia Hill, c. 33 km S of 
Tenterfield, E of New England Highway, J.B. Williams 99187 & P.J. Clarke, 22 Sep 1999 
(holo NSW; iso NE). 
Shrub or mallee to 5 m tall, sometimes a tree to 12 m. Bark persistent, long-fibrous 
('stringy') with included thin scales, branches to c. 2 cm diam. smooth, weakly 
glaucous, quadrangular. Seedling leaves not seen. Juvenile leaves elliptical, dull green, 
glaucous, glabrous, 8-11 cm long, 3-6 cm wide, petioles 2-3 cm long. Adult leaves 
semi-glossy green with a bluish sheen, becoming glossy green with age, glabrous, 
highly coriaceous, similifacial, broad-lanceolate, acute or apiculate, oblique at base, 
8-13 cm long, 2.0-5.0 cm wide; petioles 2.0-3.0 cm long, strongly flattened to 
quadrangular, usually several times twisted, decurrent into strong ribs on branchlets. 
Inflorescences axillary; umbellasters 7-flowered. Peduncles thick and broadly 
flattened, 4-10 mm long, to 7 mm wide. Mature buds sessile, glaucous, ovoid to 
rhomboid, often curved, strongly 3-4-angular, 7-10 mm long, 6-7 mm diam., calyptra 
as long as hypanthium. Flowers yellow. Filaments irregularly flexed, stamens all 
fertile, anthers reniform. Fruits sessile, tightly clustered, flattened-globular, weakly 
angular, distinctly flanged at top of hypanthium, glaucous, 4-(rarely 5)-locular, 7-11 mm 
long, 9-15 mm diam. Calyptra scar and stemonophore raised, 0.5-1 mm wide. Disc 
raised, 2-4 mm wide. Valves broadly triangular, obtuse, raised at a low angle, tips 
exserted. Seeds dark brown, semiglossy, pyramidal or D-shaped, 1.5-2 mm long; chaff 
similar, smaller. (Fig. 1).
