wings to the stem, the free part either short broad and acute, or rigid and 

 pungent-pointed. Plowers in globular heads, on axillary simple peduncles, 

 the heads rarely appearing racemose by the reduction of the flowering 

 branches. 



This series differs from the Cmifinna by the phyllodia always distichous^ much more de- 

 curreut, and often reduced apparently to lobes or teeth of the wings. A few other species, 

 such as A . C07n]}lanata^ have flattened stems, but the phyllodia are distinctly articulate on 

 the node. 



1. A. (?) bossiseoides^ A. Cunn, Herb.; BentJt. in Hook, Lond, Journ, 

 i. 323 ; not of Seem. A tall shrub, glabrous and glaucous, apparently allied 

 to A, (data, but somewhat doubtful, the flowers and fruits being unknown. 

 Phyllodia short, triangular, bifarious and decnrrcnt along the stem, each one 

 continued beyond the next below, forming continuous opposite wings, the 



xillary buds thus removed to 3 or 3 lines from the stem in the centre, as m 

 some species of Brachjsema and Bossma^ but the venation is that of the 

 "winged Acacias. Stipules small, lanceolate, oblique and almost semisagittate 

 at the base. 



N. Australia. Liverpool river, N.W. coast, J. Cunningham. A very reniarliable 

 species, originally puhlished as an Acacia, on the authority of Cuuiiingham, which I novr 

 regret, although T know of no other genus to which it is likely to belong. 



2. A. glaucoptera, Benth. in Linnrsa, xxvi. 604. A much-branched, 

 glabrous and glaucous shrub. Phyllodia erect, bifarious, oblong-falcate, de- 

 current along the stem, each one continued to the next below, but not be- 

 yond, forming opposite wings, notched at each node, where the axillary bud 

 is sessile on the stem ; the free part of the phyllodium from | to 1| in. long, 

 and 3 to 4 lines broad ai the base, with a central prominent nerve. Stipules 

 small, rigid, but not spinescent. Peduncles solitary or 2 together, under j 

 in. long, bearing each a globular compact head of very numerous (above 30) 

 small flowers, mostly 5-merous, Sepals distinct, linear-spathulate, scarcely 

 half as long as the corolla. Petals distinct, rather narrow, smooth. Pod not 

 seen. — A. bossiteoides. Seem. Eingef. Acac. t. 1, not of A. Cunn.

8. A. alata, R. Br. in Ait. Ilort. Kew. ed. 3, v. 464. A tall shinib, at- 

 taining 5 or 6 ft. or more, but flowering when only 1 or 2 ft. higb, gWm 

 or more or less hirsute. Phyllodia falcate-ovate, erect or spreading, bi ari- 

 ously decurrent along the stem, each one continued to the next below, 

 but not beyond, forming opposite wings, notched at each node, varyuig in 

 breadth from 1 or 2 lines to A in., the free part, in the ordinary forai, aboi 

 i to f in. long, usually with a gland-bearing angle on the upper eu|Y^ 

 central nerve terminating in a pungent point. Stii)ules spinescent. ^J^" ' 

 cles solitary or 2 together, bearing each a globular head of about 6 to 

 comparatively large flowers, mostly 5-merous. Bracts ovate, sessile, ^a 

 sometimes minute, sometimes nearly one-third as long as the corolla, oio. 

 more or less lobed. Petals 5, smooth, united to the middle. Pod ^^'P^H"^^' 

 oblong-falcate or lanceolate, acuminate, incurved, with thickened i""''^. jg 

 glabrous or hirsute; valves convex. Seeds ovate, transverse, the W 

 with few short folds, the last thickened into a small aril.-Wendl. tomm-
