5. CERBERA, Linn. 



(After the dog Cerberus ; from its poisonous qualities.) 

 Calyx without glands. Corolla-tube cylindrical, slightly swollen round the 

 anthers, and the throat usually somewhat dilated, without scales ; lobes ovate, 

 spreading, contorted in the bud. Anthers included in the corolla-tube* Ovary 

 of 2 distinct carpels, united by a single style, each carpel incompletely divided 

 by a very prominent placenta bearing 2 superposed ovules on each side ; stigma 

 conical, often 2-lobed at the tip. Fruit (ffom the obortion of one carpel) a 

 single nearly globular drupe, flattened on one side, with a woody endocarp, 

 usually 1-seeded. Seeds without hairs. — Shrubs or small trees. Leaves alter- 

 nate, crowded on the young branches. Flowers rather large, in terminal cymes 

 or panicles. Bracts large, deciduous. 



A genus of very few species, extending over tropical Asia and the islands of the South 

 Pacific. The Australian species is one of the most widely spread. 



1. C. OdoUam (old generic name), Octrtn.; A. DC. Prod, y'lii. ^b^; Benth. 

 Fl. Austr. iv. 306. A glabrous, erect, tall, bushy shrub or tree, with thick 

 herbaceous branches. Leaves oblong or lanceolate, acuminate, in some speci- 

 mens 4 to 6in. long, in others attaining 1ft., narrowed into a rather long 

 petiole, the primary veins transverse and parallel. -Flowers white with a 

 yellowish throat, sweet-scented, in a dense terminal pedunculate cyme. Bracts 

 coloured, f to lin. long, very deciduous. Calyx-segments oblong or lanceolate, ' 

 obtuse or acute, about Jin. long, deciduous with the bracts. Corolla-tube usually 

 above lin. long, but variable in length ; lobes obtuse or shortly acuminate, 

 from less than half as long to nearly as long as the tube. — Wight. Ic. t. 441

Var. Mugfordi, Bail. Ql. Agri. Journ. iii. 282. A small tree or large shrub. Peduncle 

 terminal, often appearing lateral from growth of shoot, 2 to Sin. long, then once or twice forked ; 

 the branches as long as the peduncle. Flowers rather large, white with a red centre, very 

 fragrant. Fruit roundish-oval, somewhat compressed, 2iin. long, 2in. broad, purplish-crimson 

 when fully ripe. Hab.: Mourilyan Harbour, near high-water mark, Wm. Mugfoi-d. I find 

 nothing to separate this plant from what may be called the normal form besides the colour of 

 the fruit, in which respect it differs from all others of the genus except, judging from pi. 2968, 

 Bot. Mag., of C. Tanghin, Hook.

(From the pale-yellow colour of flowers and timber.)

anthers, the lobes spreading, contorted in the bud, the throat without scales. 



Afithers enclosed in the tube. Hypogynous disk of minute glands or none.
