(PERTH 00336947); Hyden, 1979, RJ. Lane s.n. (PERTH 00336955); near Hyden, 18 July 1988, 
RJ. Lane s.n. (AD, G, K, MO, PERTH 00884847). 
Distribution. South-west Western Australia in Roe Botanical District (1:250,000 map 150-2, 4). 
Restricted to area south and cast of Hyden within a 25 km radius. 
Habitat. Growing in associauon with Salmon Gum ( Eucalyptus salmonophloia ) or York Gum 
(E. loxophleba ) along creek and drainage lines at lower elevations on red or brown clay, clay-loam 
or gravelly loam (R.J. Lane, pers. comm., 28 Aug. 1987). 
Flowering and fruiting periods. Flowering mainly in July — August, sometimes September or as 
early as mid-July (RJ. Lane, pers. comm., 28 Aug. 1987 and 18 July 1988). Fruiting 
mid-November to mid-December (R.J. Lane, pers. comm., 28 Aug. 1987). 
Affinities. Closely allied to several species in the A. ixiophylla alliance; it differs lrom A. ixiophylla 
in having longer, strap-like phyllodcs, all simple pubescence, and longer, glabrous legumes. 
A. lanei can be distinguished most readily from all related species (ol which A. spongolitica is 
perhaps the closest) by the white patch at each node, at the base of the phyllodcs, in the axils and at 
the base of the peduncles. 
Conservation status. 2ELK], using the criteria of Briggs & Leigh (1988). 
Etymology. Named for Richard J. Lane, the Western Australian farmer who called our attention to 
the plant in July 1986 as an excellent windbreak because it is vigorous in growth and is not browsed 
by livestock.
