26. CCELOSPERMUM, Blume. 



(Hollow-seeded.) 



(Pogonolobus, F. v. M.) 



Calyx-limb truncate or obscurely toothed. Corolla-tube cylindrical or slightly 



dilated at the top ; lobes 4 or 5, valvate in the bud. Anthers exserted, linear. 



Ovary 2-oelled, with 2 ovules in each cell, laterally almost peltately attached on 



each side of a very prominent placenta ; style 2-lobed. Fruit a drupe, with 4 



distinct hard 1 -seeded pyrenes. — Shrubs with straggling or climbing branches. 



Stipules interpetiolar, acuminate, separate or shortly connate within the petioles. 



Flowers in umbels clusters or cymes, terminal and solitary or forming terminal 



thyrsoid panicles. 



The 2 Australian species of this genus are endemic. The chief character consists in the ovules 

 and 1-seeded pyrenes being twice the number of the carpels and style-lobes, as in several species 

 of Morinda, from which Gcelospermum differs in its separate flowers. — Benth. 



Leaves smooth and shining, the veins not very prominent. Cymes rather 



dense, in oblong panicles 1. 0. paniculatum. 



Leaves rigid, prominently veined and reticulate. Umbels solitary . . . 2. C. reticulatum. 



1. C. paniculatum (flowers in panicles), F. v. M. Fragm. v. 19 and ix. 

 185; Berith. Fl. Austr. iii. 425. "Boorom," TuUy River, J. F. Bailey. A 

 woody climber, c^uite glabrous. Leaves petiolate, ovate, ovate-lanceolate, or 

 oblong, shortly acuminate, coriaceous, shining, 2 to 4in. long, the veins not very 

 prominent. Stipules forming a short truncate ring. Flowers white,' in cymes 

 forming a dense 'oblong terminal panicle. Corolla-tube nearly 2 lines 

 long ; lobes 5, rather longer than the tube. Style deeply divided into 2 linear 

 lobes. Fruit purplish, globular, with 4 1-seeded pyrenes. Seeds oblique, ovate, 

 incurved, compressed. 



Hab.: Common iit coastal scrubs north and south. 



2. C. reticulatum (veins netted), Benth. Fl. Austr. iii. 425. " I-u-luka," 

 Eed Island, Roth. A scrubby shrub, the branches often flexuose, usually 

 glabrous. Leaves obovate or oval-oblong, very shortly and acutely acuminate, 

 1 1 to 2^in. long, rigid, the pinnate veins and reticulate veinlets very prominent. 

 Stipules acuminate, not connate. Flowers pedicellate, in umbels or clusters 

 either terminal and sessile, or axillary by the reduction of the flowering branches 

 to leafless peduncles. Corolla-tube nearly 3 lines long ; lobes 4 or 5, shorter 

 than the tube, villous inside. Style with 2 linear stigmatic lobes. Fruit 

 blackish, globular, about 4 lines diameter, containing 4 bony pyrenes. — Pogorpo- 

 lobus reticulaius, F. v. M. Fragm. i. 56, and Eep. Burdek. Exped. 11. 



Hab.: Bay of Inlets, Ban/cs and Solander ; Dayman's Island, TV. Hill; Port Molle and Port 

 Denison, Fitzalan ; Eookingham Bay, Dallachy ; Eockhampton, Thozet ; Belyaudo Eiver, 

 Mitchell. 



Wood of a grey colour ; the bark, which is often very thick, produces an excellent dye. —

27. PSYCHOTRIA, Linn. 



(From Psyche, life ; in allusion to the powerful medical properties of 



some species.) 

 (Grumilia, Geertn.) 

 Calyx-limb short, truncate, toothed or lobed. Corolla-tube short ; lobes 6 or 

 rarely 4, valvate in the bud. Anthers included in the tube or shortly exserted. 

 Ovary 2-celled, with 1 ovule in each cell, erect from the base. Style short, with 

 2 stigmatic lobes. Fruit a drupe, with 2 hemispherical pyrenes, smooth or with 

 longitudinal ribs and furrows. Seed hemispherical, with furrows corresponding 

 tg those of the endocarp, or ruminate, or smooth, — Shrubs or small trees,
