6. HARRISONIA, R. Br. 



(After — Harrison.) 



Flowers hermaphrodite. Calyx small, 4 or S-cleft. Petals i or 5, almost 

 valvate. Disk hemispherical or cupular. Stamens 8 or 10, with a small 2-cleft 

 scale at the base of the filaments. Ovary globular, entire or shortly lobed, 4 or 

 5-oelled. Styles connate or distinct at the base ; stigma furrowed. Ovules 

 solitary in each cell, pendulous. Drupe small, globular, with 2 to 5 pyrenes or 

 nuts. Seeds solitary, nearly globular ; testa rather thick ; albumen scanty ; 

 cotyledons folded towards the middle.— Trees, usually armed with prickles. 

 Leaves alternate, compound. Flowers small, in pedunculate axillary cymes. 



The genus comprises only two species, natives of the Indian Archipelago, one of them 

 extending to Australia. 



1. H. Brownii (after R. Brown), A. Jus.t. in Mem. Mus. Par. xii. 540, t. 28 ; 

 Bentli. Fl. Atistr. i. 376. A shrub. Branches glabrous, often armed with short 

 conical prickles, usually in pairs, one on each side of the leaf, but probably not 

 really stipulary. Leaflets 3, ovate, acuminate. If to Sin. long, the lateral ones 

 petiolulate and oblique at the base, the terminal one narrowed at the base ; all 

 glabrous or sprinkled with a few hairs underneath. Flowers small, few together 

 in axillary cymes, on slender peduncles, shorter than the leaves. Calyx and 

 petals quite glabrous. Filaments hairy at the base. Drupe small, depressed, 

 globular, furrowed between the nuts. 



Hab.: Islands of the Gulf of Carpentaria, R. Brown (Herb. E. Rr.) We have it also from 

 Timor and from the Philippine Islands, and it probably extends over other intervening islands. 



Order XXXI. OCHNACE^. 



Sepals 4 or 5, free, imbricate, persistent. Petals 5, rarely 4 or 10, hypogynous, 

 imbricate, longer than the sepals, deciduous. Disk enlarged after flowering, 

 occasionally none. Stamens 4, 5, 8, 10 or indefinite, inserted on the disk ; 

 filaments persistent ; anthers basifixed, sometimes deciduous, dehiscing longitudi- 

 nally, or often opening by terminal pores. Ovary short, 2-celled, or elongated and 

 1 to lO-celled ; placenta axile or parietal ; style simple, subulate, acute, rarely 

 divided at the extremity, stigma simple, terminal ; ovules 1 to several in each cell 

 or indefinite, ascending or rarely pendulous, raphe ventral, micropyle superior. 

 Fruit indehiscent, drupaceous or baccate, compound, each drupe or pyrene 1 to 

 4-seeded ; or capsular and 1 to 5-celled with septicidal dehiscence. Seeds solitary, 

 few, or numerous ; albumen fleshy or none ; embryo straight or rarely curved, 

 radicle superior or inferior. — Glabrous trees or shrubs, with watery juice. Leaves 

 alternate, simple (very rarely pinnate), coriaceous; stipules 2. Inflorescence 

 paniculate or occasionally umbellate (rarely flowers solitary), bracteate. Flowers 

 hermaphrodite, conspicuous. 



Inhabiting tropical regions of both hemispheres. 



1. BRACKENRIDGEA, A. Gray. 



(After W. D. Braokenridge). 



Sepals 5, persistent, imbricate. Petals 5, equal with the calyx, deciduous, 

 imbricate. Torus thick, conical, clavate. Stamens 10, inserted on the margin 

 of the disk, filaments short ; anthers dehiscing longitudinally. Ovary deeply 

 divided into 5 parts or 5-celled ; style basilary, columnar, 5-sulcate, stigma 

 capitellate, 5-lobed ; ovules solitary in each cell, sub-basilary, curved, hippocrepi-
