8. R. tuberculosa (fruit tuberculose), Bail. Bot. Bull. ii. 12, 1891. A 

 slender erect shrub, from 5 to 10ft. in height ; branchlets somewhat 4-angular 

 and the young growth strigulose. Leaves ovate-acuminate, 2 to 4in. long, rounded 

 at the base and there nearly l^in. broad. Margins entire, primary veins distant, 

 reticulations obscure ; petioles very short, seldom exceeding 1 or 2 lines, texture 

 thin. Stipules about 2 lines long, subulate from a broad base, very deciduous. 

 Flowers on slender rigid peduncles inserted above the axils, bearing a single or 

 few shortly pedicellate flowers arising from between a pair of minute triangular 

 bracts, the peduncles lengthening out under the fruit and often in the lower 

 branches barren and forming spines. Calyx-tube slightly hairy, the free portion 

 a membranous tube about 1 line long, bearing 5 minute teeth. Corolla, stamens, 

 and style not seen. Fruit yellow, prominently verrucose, compressed and tapering 

 towards each end, over lin. long, somewhat succulent, 2-celled. Seed compressed, 

 velvety-tomentose. — R. spinuUgem, F. v. M. Vict. Nat. ix. 43, 1892.

13. GARDENIA, Linn. 



(After Dr. A. Garden.) 



Calyx-limb tubular, truncate, toothed, lobed or divided to the base into 5 or 

 more lobes. Corolla-tube cylindrical or slightly dilated upwards ; lobes 5 or 

 mo^e, imbricate in the bud. Anthers nearly sessile, usually more or less exserted. 

 Ovary 1-celted, incompletely divided by 2, 3 or rarely more projecting parietal 

 placentas, with several ovules to each placenta. Style with 2, 3 or rarely more 

 thick erect stigmatic lobes, or nearly entire. Fruit succulent, indehiscent, usually 

 crowned by the calyx. Seeds numerous, immersed in the fleshy or pulpy placentas. 

 — Shrubs or trees, the young shoots often exuding a resinous gum. Stipules 

 solitary on each side, entire, more or less connate round the stem within the 

 petioles, and often very deciduous. Flowers usually rather large and solitary or 

 3 together, terminal or axillary by the nondevelopment of the flowering-branch. 



The genus is confined to the Old World, spreading over the tropical and subtropical regions of 

 Asia and Africa. As far as hitherto observed, all the Australian species appear to be endemic. — 

 Benth.

1. G. edulis (fruit edible), F. v. M. Frar/m. i. 64 ; Benth. Ft. Austi: iii. 

 408. A small tree, apparently glabrous, the young shoots resinous. Leaves 

 small, obovate or oblong, narrowed into a short petiole, very obtuse, rarely above 

 lin. long. Flowers father small, white with a green tube, solitary or 3 together 

 and almost sessile. Calyx-limb scarcely above 2 lines long, irregularly and 

 shortly toothed, usually splitting on one side. Corolla-tube about 4 lines long,
