ACACIAS OF SOUTH-EAST QUEENSLAND. 41 



gives Kuranda to Almaden in the Cairns hinterland as additional 

 habitats. Recently^ it has been found on Bribie Island at the 

 northern end of Moreton Bay, growing in swampy ground, and 

 forming tall trees 40 to 50 feet high. Fortunately it was found 

 in fruit, and the curious spirally curled pods were confirmative 

 of its determination. The bark is dark, and at first sight 

 suggests an ironbark eucalj^pt. This species is figured in 

 Mueller's Aust. Ac, dec. 9, pi. 6. Along the tropical coast 

 it is called the island wattle. 



IV. — Acacia cunninghaviii Hook, was formerly known round 

 Moreton Bay as the black wattle. It grows in the same situa- 

 tions as A. aulacocarpa, which it often closely resembles in 

 height and phyllodes. When in fruit it can easily be dis- 

 tinguished by its much narrower pods ; Avhen without fruit 

 it can be separated from its ally bj^ the frequent anastomoses 

 of the veins of the phyllodes, and by the triangular outline 

 shown in a cross-section of the young twigs. 



V. — Acacia fimbriata A. Cunn. is laiown as the creek-side 

 and flax-leaved Avattle, and loves the sides of streams and the 

 borders of marshes, being found in coastal country from Bris- 

 bane to Broadsouncl. It was formerly known and distributed 

 in Queensland as Acacia lini folia Willd., from which Mr. 

 J. H. Maiden has shown that it must be sj)ecifically separated. 

 The main differences are in the phyllodes, which in A . fimbriata 

 are larger, broader, and fringed along the margins with minute 

 cilia. Mr. Maiden^ has suggested the vernacular name of 

 fringed wattle, leaving that of flax-leaved wattle to the true 

 A. linifolia. This species is figured in Forest Flora, vol. v, 

 pi. 157. It is a tall shrub or small tree, seldom reaching 20 

 feet in height. 



VI. — Acacia implexa Benth. is found in Queensland from 

 the Brisbane to the Burnett River along the coast, and inland 

 to the valley of the Dawson, the great southern tributary of 

 the Fitzroy. In S.E. Queensland it is typically a mountain 

 species, and is specially characteristic of such basaltic masses 

 as Tambourine, Beech Mountain, and Springbrook. It forms 

 trees reaching 30 or 40 feet or more. The linear pods, not more 

 than 3 lines broad when ripe, form a twisted and curled-up 

 mass, hence the specific name. It is figured in Mueller's Aust. 

 Ac, dec 8, pi. 2 ; and in Maiden's Forest Flora, vol. v, pi.
