A considerable genus, spread over tropical Asia and the Indian Archipelago, extending 

 also to New Zealand. The Australian species are all endemic. The genus is readily known by 

 the tubular disk enclosing the ovary witliin the staminal tube.

1. D. latifolium, Benlh, Leaves glabrous; leaflets in our specimens 

 4 or 5, ovate or broadly oval-oblong, shortly aeuniinate, 3 to 4 in. long, 

 oblique at the base, somewhat coriaceous. Flowers in sessile or shortly 

 pedunculate clusters, along a simple, axillaiy, nearly glabrous peduncle of 4 

 to 5 in. Pedicels short, slightly pubescent. Calyx cupular, not 1 line long, 

 With 4 very short broad teeth. Petals 4, pubescent outside, about 3 lines 

 long, valvate in the bud, free from the staminal tube. Staminal tube truncate, 

 and shortly and irregularly 8-toothed. Disk broadly tubular, sprinkled with 

 ? few minute hairs. Ovary, in the flowers examined, 2-celled, with 2 ovules 

 in each cell, pubescent, tapering into an elongated style i stigma disk -like.

2. D. Fraseranum, Benth, A tree of 80 to 130 ft., the young leaves and 

 shoots slightly pubescent, glabrous when full-grown. Leaflets 5 to 9, oblong- 

 hinceolate or ellipticab acuminate, 3 to 6 in. long, narroued and equal at the 

 hase, bearing occasionally iwh^ of hairs in the axils of the principal veins 

 linderneath. Panicles in the upper axils short, loose, divaricately branched, 

 slightly pubescent. Calyx cupular, about 1 line long, shortly and broadly 

 4-lobed. Petals 4, about 3 lines long, neariy glabrous, adnate to the staminal 

 tiJbe to about half tlieir length. Staminal tube 8-toothed, glabrous outside. 

 ■L>isk broadly tubular, rather longer than the ovary. Ovary hirsute, 3-celled, 

 ^'ith 2 ovules in each cell. Pruit not seen. — Hartighsea Fraserana, A. Juss.

3. D. Muelleri, Benth. A tree of 60 ft. or more, glabrous or nearly so, 

 ^^cept the very young shoots and inflorescence. Leaves 1 to 2 ft. long ; 

 leaflets 11 to 21, from ovate to almost lanceolate, shortly acuminate, 3 to 6 

 in, long, very oblique at the base, one side rounded, tlie other truncate and 

 shorter, almost coriaceous. Panicles pyramidal, f to 1 ft. long, much- 

 biwiched and many-flowered. Calyx cupular, 1 to | line long, pubescent, 4- 

 iobed. Petals 4, nearly glabrous, about 5 lines long, adhering to the stami- 

 nal tube to about two-thirds their length. Staminal tube truncate and mi-
