oblong-fusiform, opening loeulicidally in 2 woody valves leaving the placenta 
free. Seeds very flat, with a broad transparent wing. — Trees. Leaves simple, 
whorled or opposite. Flowers yellow in terminal panicles. 
The species are few, and, besides Queensland, are found in Malacca and New Caledonia. 
Large tree. Young growth softly tomentose. Leaves opposite or in whorls 
of 4 1. D. tetraphylla. 
Small tree. Young growth densely hirsute. Leaves opposite or in whorls 
of 3 ... 2 . D. hirsuta. 
1. D. tetraphylla (leaves in whorls of 4), 7?. Br. Prod. 449 ; Benth. FI. 
Austr. iv. 540. Tree often lofty, stem with a diameter often exceeding 3ft. ; 
bark thick, soft, and somewhat corky ; the thick branchlets, under side of the 
leaves, and inflorescence covered with a thick soft tomentum, often assuming a 
golden or bronzed hue, and consisting of single or clustered but scarcely 
stellate hairs. Leaves crowded at the end of the branches, in whorls of 4 
or the first leaves of young shoots opposite, on short petioles, ovate, obtuse, 
entire, 1 to 2ft. long, 1ft. or more broad, or those immediately under the 
panicle 6 to 8in., the upper surface glabrous or slightly scabrous. Flowers 
yellow, in a dense terminal panicle, nearly sessile above the last leaves, the 
primary branches whorled, each one dichotomously branched, with a flower 
shortly pedicellate in each fork. Bracts linear, minute. Calyx coriaceous, 
about |in. long, the lobes acute, as long as the tube. Corolla-tube shortly 
exceeding the calyx, the lobes as long as the tube, broadly rounded. Stamens 
and style exceeding the corolla by an inch or more, very divergent. Hypogynous 
disk rather thick. Capsule (only seen open with the valves detached) 2 to 3in. 
long, the valves hard and woody, smooth inside with a longitudal line probably 
where the dissepiment was attached, the placenta-bearing dissepiment not 
broad and rather thick. Seeds apparently ripe but the embryo not perfect in 
those examined. — F. v. M. in Seem. Journ. Bot. v. 212; Bidweria nobilissinia

2. D. hirsuta (hairy), Bail. Bot. Bull. xiv. 11. Described by collectors 
as a small tree. Branchlets quadrangular and densely hirsute. Leaves opposite 
or in whorls of three, narrow-lanceolate in outline, but very irregular, 
the ends of some being broadly truncate, attaining 20in. in length, with a 
breadth* of G^in. about the centre, margins repand, crenulate, or deeply and 
very irregularly toothed, base cordate, and much undulate, petioles | to H in., 
hirsute. Calyx |in. long, campanulate, coriaceous, appearing 3-lobed from 4 of 
the lobes being joined in pairs to near the apex, forming as it were two broad 
emarginate lobes, hairy outside, the inside bearing minute scale-like glands. 
Corolla yellow, ringent, lin. long, spreading to l^in. wide, the lobes blunt, 
longer than the tube. Stamens exceeding the corolla by about l|in. ; style 
about the length of the stamens, the stigraatic lobes ovate-apiculate. No fruit 
obtained.
