316 XL. SAHNDACEiE. [Dodonced. 



11. D. Hansenii (after Lars Hansen), -/''. c. M. Vict. Nat., 1891. A shrub 

 of about 12ft. high, glabrous, hardly viscid. Leaves attaining the length of 2in., 

 slightly shining, on rather conspicuous petioles, chartaceous, broadly and some- 

 what bluntly lanceolate, but more gradually narrowed into the base than into the 

 apex, subtle-venulated. Flowers Unknown. Kacemes when fruiting below the 

 leaves corymbose, few-flowered or reduced to 3 or two flowers ; pedicels rather 

 long. Sepals early deciduous. Capsule usually 4-celled, its capsular portion 

 hardly as long as broad, its wing-appendages ascemiingly divergent, venulous, 

 and from 4 to nearly 6 lines broad, considerably broader than high, rounded- 

 blunt at the upper end, ceasing before the base and before the middle summit of 

 the valves ; dissepiments seceding from the axis, closing permanently the carpels. 

 Young seeds longer than broad, almost truncate and also turgescent around the 

 hilum. Eipe seed not obtained. — F. v. M. I.e. 



Hab.: Stuart's Eiver, Stephen Johnson. 



Among the Jew species with fruit dissepiments seceding from the axis this comes nearest 

 to D. platyptera, but the leaves are of larger size, of darker green, of thinner texture, and 

 not of conspicuously glandular punctuation ; further, the appendages of the fruit are perceptibly 

 larger, and turn almost diagonally upwards, while those of jD. platyptera remain nearly at a level 

 with the vertex of the cells. The flowers and mature seeds may also yet show specific differences. 

 From D. pachyneura our new plant is also distinguished by much larger leaves, with fainter 

 and more divergent venulation, also by the greater extension of the fruit appendages. The shape 

 of the fruit is much like that of D. macrozyga and D. megazyga, but its dehiscence, as well as 

 the foliage, are very different. The leaves resemble those of D. lanceolata and D. triquetra. —

12. D. Stenophylla (slender leaves), F. v. M. Fragm.. i. 72 ; Benth. Fl. 

 Austr. i. 480. Glabrous and viscid. Leaves narrow-linear, rigid, 2 to 6in. long 

 and almost 2 lines broad, the margins usually thickened and entire. Flowers of 

 D. viscosa, in short loose racemes or almost cymose panicles. Sepals ovate. 

 Capsule small, the wings broadly oblong or obovate, diverging, not reaching to the 

 style nor to the base of the carpels ; dissepiments splitting and falling off with the 

 valves, leaving only the filiform axis persistent. Seeds shining. 



Hab.: Broadsound, E. Brown; Burdekin' Eiver, F. v. Mueller; Comet Eiver, Leichhardt ; 

 and near Moreton Bay. 



In flower, this species is scarcely to be distinguished from D. attenuata, vax. linearis; but the 

 fruit is very different. — Benth. 



13. D. triangularis (triangular), Lindl. in Mitch. Trop. Austr. 219 

 (male plant); Benth. Fl. Amtr. i. 480. An erect shrub of 3 to 4ft., 

 glabrous, pubescent or softly villous. Leaves obovate - cuneate or 

 almost triangular, rounded-truncate or 3-toothed at the end, or very rarely 

 elliptical-oblong, ^ to lin. or rarely IJin. long, coriaceous, 1-nerved, 

 the lateral veins quite inconspicuous. Flowers axillary, solitary or clustered, on 

 short pedicels. Sepals narrflw-lanceolate, rather thick. Anthers as in D. 

 triquetra, narrow, acuminate, exceeding the calyx. Capsule glabrous or 

 pubescent, 3 or 4-angled, the angles rarely dilated towards the top into very 

 narrow wings; dissepiments remaining attached to the axis, or very rarely 

 deciduous but not splitting. — D. mollis, Lindl. in Mitch. Trop. Austr. 212 (with 

 pubescent capsules) ; D. trigona, Lindl. I.e. 286 (with glabrous capsules) ; D. 

 Limdleyana, F. v. M. PI. Vict. i. 88. 



Hab.: Suttor Eiver, F. v. Mueller; near Mount Owen, Mount Faraday, and Mantuan 

 Downs, Mitchell; near Brisbane and Ironbank forest, Leichhardt; and Stanthorpe, Alex. 

 McPherson. 



14. D. megazyga (pairs of leaflets large), F. v. M. Benth. Fl. Austr. i. 488 ; 

 Fragm. ix. 86. A tall shrub or tree of 80ft., glabrous and slightly viscid, the 

 young branches acutely angled. Leaves mostly pinnate, the rhachis conspicuously 

 winged; leaflets usually numerous, sometimes above yO, lanceolate, acute, ^ to lin. 

 long ; in some specimens the lower leaves of the branches reduced to very few
