1. B. spinosa (spiny) Cav. Ic. iv. 30, *. 350; Bmth. Fl. Austr. i. 114. A 

 shrub or small tree, glabrous, and when young very bushy, the smaller branches 

 often reduced to short subulate thorns. Leaves very variable, most frequently 

 clustered, obovate, oblong or cuneate, obtuse, truncate or notched, ^ to lin. long, 

 narrowed at the base, and sometimes shortly petiolate, green on both sides ; in 

 luxuriant specimens they vary to oblong-lanceolate, 1 to 2in. long ; in a few 

 others they have occasionally a few coarse teeth at the top. Flowers white, 

 usually very numerous, in a broad, pyramidal, terminal panicle, arranged along 

 its branches in short racemes, on pedicels of 1 to 3 lines ; occasionally the 

 panicles are reduced to short racemes or to 1 or 2 terminal flowers. Bracts 

 minute and very fugacious. Sepals small, also falling off long before the petals 

 open. Petals narrow, about 2 lines long. Capsule 8 to 4 lines or, in the var. 

 incann, sometimes 5 lines broad. — DC. Prod. i. 847; Bot. Mag. t. 1767; Hook.

3. B. tenuifolia (thin-leaved). Bail. A tall shrub or small tree, the 

 branchlets more or less corrugated and bearing prominent lenticels. Leaves 

 lanceolate, about 2^in. long, the apex obtuse, tapering to a rather slender petiole 

 2 or 8 lines long, smooth and rather glossy with the erecto-patent parallel nerves 

 prominent above, the under side covered with a thin tomentum, the nerves and 

 principal veins showing as dark lines, margins entire. Panicles elongated upon 

 peduncles of from only a few lines to 2in. Flowers pedicellate, bracts narrow- 

 lanceolate, an upper one often very narrow, ferruginous. Sepals lanceolate, 

 ciliate. Petals recurved, oblong- linear, 2| lines long, marked with 3 lines ; 

 filaments about as long as the petals, subulate. Ovary glabrescent. 



Hab.: Barron Eiver, E. Cowley; Shaw Island, Lord Lamington; Northcote, iJ. G. Burton; 

 Herberton, J. F. Bailey. This species has more membranous leaves, more slender branchlets 

 and panicles than any of the other species of the genus.
