1. A. multiflora (flowers numerous), Bentli. Fl. Austr. i. 463. A tall shrub 

 or small tree, glabrous except the inflorescence. Leaflets 2 to 6, ovate or oblong, 

 very obtuse, 2 to 3in. long or rarely more, sometimes 2|in. broad, distinctly 

 petiolulate, coriaceous and strongly reticulate. Panicle peduncular above the 

 last leaves, oblong or pyramidal, minutely tomentose-pubescent. Flowers very 

 numerous, the small scale-like bracts more conspicuous than in the other species. 

 Flowers of A. hemiglauca. Ovary slightly pubescent. Samarse 1 to Ifin. long, 

 including the straight or falcate wing, very divaricate, pubescent or nearly glabrous. 



Hab.: Cape York and Trinity Island, M'GilKvray ; Brisbane Biver, W. Hill, F. v. Mueller i 

 Eookhampton, Thozet. 



2. A. hemiglauca (referring to light colour on under side of leaf), Benth. 

 Fl. Avstr. i. 463. White Wood, Cattle Bush. " Boorbal," flower " Boorbal- 

 min," St. George, Wedd. A tall shrub or small tree, quite glabrous except the 

 flowers, and more or less glaucous. Leaves usually pinnate ; leaflets few, from 

 narrow-oblong to linear, obtuse or scarcely acute, from 2 or 3 to 7 or Sin. long, 

 often somewhat falcate, narrowed at the base, but rarely petiolulate, rigidly 

 coriaceous, with numerous pinnate and reticulate veins and a somewhat thickened | 

 margin, the common petiole terete or nearly so ; sometimes, however, the petiole 

 becomes winged, or the leaves are quite simple, oblong, or linear, or the leaflets 

 are decurrent on the petiole forming a large 2 or 3-lobed leaf, or rarely the simple 

 leaf is ovate-lanceolate, and 8 to lOin. long. Panicles rather dense, the rhachis 

 and branches glabrous or nearly so ; pedicels 1 to 2 lines long. Sepals orbicular^ 

 nearly glabrous, 1^ or the inner ones nearly 2 lines long. Petals pubescent, 

 oblong, 3 to 4 lines long, with a hirsute scale at the base. Filaments pubescent. 

 Ovary densely silky-pubescent. Samar® pubescent, with minute appressed hairs, 



1 to l|in. long including the wing, which is nearly as broad as long, the cavity 

 hairy or nearly glabrous inside. — Thouinia hemiglauca, F. v. M. Fragm. i. 98. 



Hab.: E. coast, R. Brown; Oxley's Station, Leichhardt; Eookhampton, Thozet; Brisbane 

 River, A. Cunninghavi, Fraser ; Mooni River, Mitchell; and Cooper's Creek, Victorian

This small tree is often cut down for fodder in times of drought, hence known as Cattle Bush. 



Wood of a close grain, yellowish, and hard. — Baileifs Cat. Ql. Woods No. 98. 



3. A. variifolia (leaves variable), F. v. M. Herb.; Benth. Fl. Austr. i. 463. 

 A tall shrub or small tree, the young branches and panicles softly velvety- 

 tomentose. Leaves or leaflets from oblong to linear, apparently as variable as in 

 A. hemiglauca, but longer, often above 8in., very much more reticulate, the 

 common petiole usually broadly winged, the wing also much reticulate. Panicle 

 loose. Sepals silky pubescent, about IJ line long. Petals twice as long. 

 Filaments hairy. Samaras softly tomentose, 2in. long including the wing, which 

 is fully twice as long as broad, the cavity pubescent inside. — Thouinia variifolia, 

 F. V. M. Fragm. i. 46.

8. SAPINDUS, Linn.

 any. Disk annular. Staniens usually 8 ito 10. Ovary 2 to 4-lobed, 2 to 4-celled,
