1. B. australis (Australian), Hook. Bot. Mhr. i. 157, t. 45 ', Benth. Fl. Austr. 

 I. 445. A scrubby, much-branched, thorny shrub of 1 to 2ft., usually glabrous. 

 Branches green, terete, the smaller ones reduced to stout spines of 1 to l^in. 

 Leaves often appearing clustered from the shortness of the shoots, oblong or 

 cuneate, obtuse or emarginate, rarely exceeding fin. Pedicels solitary or 

 clustered in the axils of small leaves, which soon fall off from the very short 

 branches, the flowers then appearing densely clustered under the spines. Flowers 

 sweet-scented, white. Calyx-tube broadly campanulate above the disk, the limb 

 spreading to about 2 lines diameter. Petals spathulate or oblong-cuneate, hood- 

 shaped. Ovary deeply immersed in the disk, the short free part 3-lobed. Fruit 2 to 3 

 Hues diameter. — Hook. f. Fl. Tasm. i. 69 ; Reissek. in Linnsea, xxix. 266 ; F. v.

 small, in terminal or axillary racemes ; rhachis often passing into tendrils. 



The species are scattered through the tropics. 



Leaves on short petioles. Fruit, including the wings, 4 lines diameter . . 1. G. australiana. 

 Leaves on longish petioles. Fruit very small, including the wings about 2

1. Ct. australiana (Australian), F. v. M. Fragm. iv. 144, and Bail. Bep. 

 Bell. Ker Eccp., 1889. A tall, velvety- tomentose climber. Leaves cordate or

 long, IJ to Sin. broad, penninerved, tomentose on both sides. Petioles somewhat 

 short, the spiciferous panicles wide- spreading. Bracts narrow, semi-lanceolate, 

 scarcely 1^ line long. Flowers subsessile, densely hoary. Fruit 8-winged, 

 3-celled, including the wings about 4 lines diameter, tomentose, like the rest of

 branches and petioles fusco-tomentose. Leaves ovate or cordate-orbicular, entire 

 except the somewhat acute apex, the upper side glabrous, under side moderately 

 pilose, 2 to Sin. long, 1| to 2in. broad. Petioles somewhat long. Nerves 

 conspicuous on the under side. Stipules caducous. Flowers in spicifbrm 

 terminal panicles, about Bin. long. Fruit glabrous, including the wings about 

 2 lines broad.
