Distribution. South-west Western Australia mainly in the Avon, Roe and Eyre Botanical Districts 
but with a few collections from the eastern part of the Coolgardic Botanical District and one outlier 
at Madura in the Nullabor Botanical District (1:250,000 maps H50-12, 15, 16; H51-15; H52-13; 
150-3, 4, 7, 8, 12; 151-1, 2, 5, 6). Mainly scattered throughout an area bounded by Chiddarcooping 
Hill Nature Reserve and Trayning, south to the Fitzgerald River, cast to near Sparkle Hill (c. 100 
km NE of Espcrance) and north to the Fraser Range and north-east to near Buningonia Spring; the 
Madura collection is from along the Eyre Highway within 175 km of the border with South 
Australia, if the collection data are correct. 
Habitat. In open shrub mallec or low mallee woodland often in association with Eucalyptus spp. 
(E. wandoo , E. platypus, E. salubris, E. transcontinentalis, E. longicornis, E. salmonophloia, 
E. redunca), rarely in open savanna or along creek course, on soils of clay, sandy or gravelly loam 
or brown, red or white sand. 
Flowering and fruiting periods. Flowers collected in late May to September; mature fruits with 
seeds collected in December and January. 
Affinities. Material of the new species has usually been referred to the eastern A. ixiophylla which 
differs by its stellate hairs intermixed with simple ones on many parts, by its relatively well-marked 
main nerves, by the position of the phyllode-gland at the distal end ol' the pulvinus, pubescent 
ovary, and semiconstricled legumes which are dull and villose, at least marginally. A. verricula is 
also the nearest relative of A. lobulata. 
Synonomy. Acacia glutinosa F. Mucll. was published in Fragm. 4: 6 (1863) with the type indicated 
only as having been collected in Western Australia by G. Maxwell. Two sheets at Herb. MEL 
which we and others consider to comprise Mueller’s type, each bears a flowering branchlct and a 
packet of fruits and seeds. We have checked the protologue, point by point, with the MEL sheets 
(1553911 and 1553912) and it is clear that Mueller had this material before him when he described 
the species. There is also a sheet at K, bearing only a flowering branchlct, annotated by Mueller as 
A. glutinosa, which is surely a part of the type collection. The flowering material at both K and 
MEL is labelled in Mueller’s hand as being from the Melbourne botanical garden but one of the 
MEL sheets (1553911) is annotated by Mueller as " Acacia ixiophylla Bcnth.", the other (MEL 
1553912) as "Acacia glutinosa F. M./ A. ixiophylla var. Bcnth.", also in Mueller’s hand. Both MEL 
sheets bear packets containing mature pods and seeds, but only sheet 1553911 is annotated to 
suggest the contents were collected by Maxwell, the collector cited in the protologue. This packet
