Associated with the above trees was another species of Acacia 

 known locally as Motherumbung, and which has not yet been 

 identified, as pods were not procurable. So far as seen, it 

 appears to have much the same habit as A. doratoxylon, growing 

 in clusters with long thin stems about 2-4 inches in diameter 

 and perhaps 20-30 feet high (Plate ii.). But botanically it is quite 

 a different plant, for while the Currawong has phyllodia with 

 numerous tine parallel nerves and flowers arranged in spikes, the 

 Motherumbung has " leaves " with a distinct midrib and lateral 

 veins placed at a fairly acute angle, and its flowers arranged in 

 capitula or heads instead of spikes. The Motherumbung has 

 narrow-lanceolate plwllodia, obtuse, often with a callous point 

 sometimes slightly curved, rarelj^ exceeding 2 lines broad, and 

 from about f of an inch to over 2 inches long, the terminal ones 

 being short and very glutinous towards the ends, 1 -nerved with 

 sometimes a gland about 2 lines from the base. The peduncles 

 are solitary, about 2-3 lines long, bearing a rather small globular 

 head of about 25 flowers. Pinnae on the seedlings soon disappear, 

 but three or four pairs were noticed on the lower phyllodia of 

 one plant. Judging by the description, it appears to have 

 affinities to A. Gnidhim, Benth., a Queensland species (B.Fl. ii. 

 359), but in Bailey's 'Queensland Flora' there is nothing to 

 show that this Acacia has been collected except at Mount Pluto 

 by Mitchell, and the pods are not described. 



Specimens of Motherumbung, without pods, are in the National 

 Herbarium, Botanic Glardens, Sydney. 



The Black Wattle of the district appears to be a form of A. 

 dealhata, though the glaucous appearance seen on this species in 

 the highlands is absent, the green leaves thus giving the trees 

 the aspect of A. deciirrens^ Willd., the common Green or Black 

 Wattle of the coast. 



A. spectabilis is often known in this locality as Blue Wattle, 

 chiefly from the colour of the bark on the stems, and A. decora 

 is referred to as Silver Wattle, but these names are not so con- 

 stantly used for those species as that of Brigalow is for A.
