1. D. triquetra (referring to angles of branches), Andr. Bot. Rep. t. 280. 

 "lunginga Kilamul," Moreton Bay, Watldns. Erect, usually tall, glabrous, 

 not very viscid, the young branches flattened or angular. Leaves from oval- 

 elliptical to oblong-lanceolate, acuminate, 2 to 3 or rarely 4in. long, the pinnate 

 and reticulate veinlets few and fine, usually scarcely conspicuous. Pedicels 

 slender, in short, oblong, compact panicles or racemes. Sepals minute, rarely | 

 line long. Anthers linear, often If line long. Styles, when long, attaining fin. 

 Capsule of D. viscosa, usually middle-sized. Seeds brown, very smooth and 

 shining.— DC. Prod. i. 617 ; F. v. M. Fragm. i. 75, and PL Vict. i. 226.— X>.

Hab.: Brisbane Eiver, Moreton Bay to Eockingham Bay. 



The Fiji Island plant referred by A. Gray and Seemanu to D. triqueti-a appears to me to be 

 one of the common forms of D. viscosa. — Benth. 



Wood of a light colour, except near the centre, which is dark, close-grained, tough, and nicely 

 marked.— Bailey's Cat. Ql. Woods No. 107. 



2. B. lanceolata (lanceolate), F. v. M. Fragm. i. 73 ; Benth. Fl. Austr. i. 

 475. Very closely allied to D. triquetra, with the same angular branches, smooth, 

 almost veinless leaves, slender pedicels, and very shining seeds, and scarcely 

 distinguishable except by the sepals, which are from 1 to 1^ line long. The 

 leaves are perhaps generally rather narrower, and the capsule-wings broader, but 

 neither of these characters can be relied upon.

 Brown; Cape Cleveland, ^. Cunningham; Sunday Island, M'Gillivray ; Pahn Island, Hcnme ; 

 Port Denison, Fitzalan. 



3. S. petiolaris (petiolate), F. v. M. Fragm. iii. 13 ; Benth. Fl. Austr. i. 

 475 ; Fragm. ix. 89. Leaves rounded at the base, here and there truncate, veined as 

 in D. viscosa, but sometimes narrowed at the base, on petioles of 2 or 3 lines. 

 Sepals 5, narrow. Stamens 10, 8 times as long as the calyx. Anthers apiculate. 

 The single capsule seen not yet full-grown, but, in that state, does not appear at 

 aU different from the larger varieties of D. viscosa, of which this plant may 

 probably prove to be a variety. — Benth. (in part).

4. 2>. viscosa (viscid), Linn.; DC. Prod. i. 616 ; Benth. Fl. Aitstr. i. 475. 

 Hop Bush. " Tecan," St. George, Wedd. A shrub, sometimes low and stunted, 

 more frequently tall, glabrous, and usually more or less viscid, the young branches 

 frequently compressed or somewhat triangular, but much less so than in D. 

 triquetra. Leaves simple, varying from broadly oblong-lanceolate, acute or 

 acuminate, and 3 or 4in. long, to narrow-lanceolate, or oblong-cuneate and very 

 obtuse or almost linear-cuneate, always narrowed into a more or less distinct 

 petiole, entire or obscurely sinuate, or rarely almost 3-toothed at the end, the 

 pinnate veins usually rather numerous and very divergent, sometimes scarcely 

 conspicuous. Panicles or racemes usually short and terminal, or reduced to 

 axillary clusters. Sepals ovate, usually as long as or rather longer than the 

 oblong obtuse anthers. Style rarely lengthened out. Capsule very variable in 

 size, the wings continued from the base to the style, or nearly' so, either equally 

 rounded at the top and at the base or more contracted at the base. Seeds rather 

 large, dark-coloured or black, opaque or scarcely shining. — Hook. f. Fl. Tasm. i. 

 55 ; F. V. M. PI. Vict. i. 85.

 Bay, A. Cunningham; Cape Upstart and Port Curtis, M'Gillivray ; Eookhampton, Thozet ; 

 Moreton B&j,.Fraser, A. Cunningham, and others ; Condamine Eiver, and many other localities. 



The form growing in India is said to be used for engraving, turning, tool-handles, and 

 walking-sticks. Has a white sapwood and a hard dark-brown heartwood, which is close-grained. 

 The leaves of a form of this species are said to be used in some parts of India as a febrifuge. 



Wood of a brown colour, close-grained, and hard. — Bailey's Cat. Ql. Woods No. 108.
