Typus: 8 mi. [12.8 km] E of Gnowangerup, Western Australia, 23 Aug. 1964, K.R. Newbey 1302 
(holo: PERTH; iso: CANB, K, MEL, PERTH). 
Spreading shrubs 1-2.5 m tall, 1.5-4 m diam. Bark rough, grey. Branchlets sparingly to 
sparsely puberulous or pilosulosc, often resinous apically. Stipules persistent, subulate to 
subulate-triangular, to 1 mm long, ciliolate. Phyllodes oblong to elliptic, more or less asymmetric, 
apex rounded to subtruncate and retuse, mucronulate to rostrate-mucronulatc, base acute, pulvinus 
0.5-1 mm long, glabrous, blades (12-)15-20(-22) mm long, (4-)5-7(-8) mm wide, thin-coriaceous, 
inclined, straight, glabrous or rarely few micro-hairs on margins, two longitudinal main nerves on 
each face distant, salient, secondary nerves impressed and openly reticulate. Gland conspicuous, 
annular, w'ider than phyllode thickness, situated on upper margin of phyllode 2-3 mm above 
pulvinus. Peduncles 3-5 mm long, solitary, glabrous; basal peduncular bracts persistent, broadly 
ovate, 1.5 mm long, glabrous except ciliolate. Flower-heads globular, 4 mm diam., 22-30-flowered. 
Bracteoles spalhulate, blade broadly ovate, acuminate or acute. Flowers 5-merous. Sepals less than 
1/2 length of petals, 1/2-3/4-united, sericeous externally. Petals narrow-elliptic, free, glabrous. 
Ovary granulose or papillose, sometimes puberulous or sericeous apically. Legumes linear, 
depressed between seeds, 4-7 cm long, 3-4 mm wide, chartaceous, in one or two coils, glabrous, 
usually strongly resinous. Seeds longitudinal, oblong, 4-5 mm long, 2.5-3 mm wide, glossy 
dark-brown; pleurogram narrowly U-shaped, c. 3 mm long; aril apical. 
Specimens examined. WESTERN AUSTRALIA: Wagin, 10 Sept. 1955, J . Graffin s.n. (PERTH 
00697192); 2 miles [3.2 km] E of Jerramungup, K.R. Newbey 488 (PERTH) and 488D (MEL, 
PERTH); 8 miles [12.8 km] E of Gnowangerup, K.R. Newbey 1302D (PERTH); 7 miles [1 1.2 km] 
NE of Ongcrup, K.R. Newbey 3686 (PERTH); 4 km ENE of Jerramungup, K.R. Newbey 9535-1 
(MELU, PERTH); 2.4 miles [3.8 km] E of Jerramungup on road to Ravcnsthorpe, M.D. Tindale 248 
& B.R. Maslin (PERTH). 
Distribution. South-west Western Australia in southern Avon and Roe Botanical Districts 
(1:250, OCX) maps 150-7, 8). Infrequent but locally common from Wagin ESE to Jerramungup. 
Habitat. Found predominantly in Eucalyptus occidentalis woodland on sandy or granitic loam. 
Flowering and fruiting periods. Flowers August — September; legumes with mature seeds collected 
in December. 
Affinities. Related to A. lanuginophylla which is very distinct because of its densely lanale 
branchlets, phyllodes, peduncles, bracts, bracteoles and legumes. Both species have the same sort 
of annular phyllode-gland, stipules, solitary flower-heads, ovale bracteoles and broadly ovate 
bracts. 
Conservation status. 3R, using the criteria of Briggs & Leigh (1988).
