and more unequally divided calyx, not appendioulated petals, and form of the anthers ; from 

 Hedraianthera in neither anthers nor stigma sessile, not hard pericarp, and the shape of the 

 arillus ; from Denhamia in the structure of the anthers, undivided stigma, not bony pericarp, 

 and seeds much emerging from the arillus. — F. v. M., I.e. 



Hab.: In the highest regions of Mount Bellenden Ker, descending to about 4000tt. , W. Sayer 

 F. V. M.l The shrub is also abundant at Pimpama and on Tambourine Mountain ; flowers 

 minute, deep-red. 



2. H. oppositifolia (opposite leaved), F. v. M., Vict. Nat., May 1892. 

 Leaves 1^ to Sin. long, on rather long petioles, mostly opposite, ovate-lanceolate, 

 bluntly acuminate. Panicle many-flowered, cymose, terminal and axillary. 

 Sepals connate towards the base. Petals ovate, beset outside with short appressed 

 hairs. Filaments much incurved, considerably longer than the anthers, stoutish, 

 dark-purplish, hispidulous. Style very short, stigma much broader, depressed ; 

 disk and ovary glabrous. Fruit not seen.

6. DENHAMIA, Meisn. 



(After Captain Denham, in African explorer.) 



(Leuoooarpon, A. Eich.) 



Calyx 5-cleft. Petals 5. Stamens 5, inserted on the margin of the disk ; 



filaments subulate ; anthers ovate. Disk broadly cupular, rather thick. Ovary 



1-celled, with 3, or rarely 4 or 5 parietal placentas, or completely divided into as 



many cells ; style short, with as many stigmatic lobes as cells or placentas. 



Ovules 3 to 8 to each cell or placenta. Capsule ovoid or globular, opening in 



thick woody or bony valves, bearing the placentas or dissepiments in their centre. 



Seeds enclosed in a fleshy arillus ; albumen fleshy ; cotyledons flat.— Shrubs or 



small trees, glabrous and more or less glaucous. Leaves alternate, rigid, entire, 



or toothed. Flowers small, in few-flowered cymes or racemes. 



The genus is exclusively Australian, and on account of the parietal plaoentation of two species 

 has been by some referred to Bixinece ; but the disk, stamens, general habit, etc., are those 

 peculiarly oharaoteristio of Gelastrinece.—Benth. 



Ovary 1-oelled ; placentas (4 to 8 ovulate) not meeting in the axis. Veins 

 of the leaves not very prominent. 



Flowers racemose. Style distinct 1. D. oleaster. 



Flowers in cymes or narrow panicles. Style very short, branched . . 2. D. obscura. 

 Ovarv 3-celled, placentas (3 or 4-ovulate) united in the axis. Leaves 



prominently veined ^ TX pUtmformdes. 



Placentas 4 to 6-ovulate. Leaves green on both sides 4. D. vmdissima. 



1. D. Oleaster (Oleaster-like), F. v. M. in Tram. Phil. Inst. Vict. iii. 29 ; 

 Benth. Fl. Austr. i. 401. A tall shrub with slender branches. Leaves lanceolate, 

 acute, or rarely obtuse, 2 to 3in. long, entire or remotely toothed, narrowed into 

 a very short petiole, coriaceous, the veins scarcely conspicuous. Flowers m short, 

 simple, axillary or terminal racemes, the pedicels very rarely bearing 2 flowers. 

 Calyx-segments broadly ovate or orbicular. Petals nearly 2 Imes long. Disk 

 thicker and filaments longer than in the other two species. Ovary 1-celled, 

 tapering into a style of at least f line, the stigmatic lobes very short. Placentas 

 3, with 4 to 6 ovules to each. Fruit not s&m.—Melicijtus (?) oleMter, Lmdl. in 

 Mitch. Trop. Austr. 383.
