sistent, segments acute, mucronulate, spreading in their 

 upper half, closely imbricated below. Corolla one inch 

 long, one inch across, lilac and white, (violet-purple in my 

 specimens. II.) striated, glanduloso-pubescent, ringent, its 

 limb dilated and spreading, crenate, the upper lip two- 

 lobed, the lower three-lobed, of which the central lobe is 

 the largest and emarginate ; tube campanulate, dilated on 

 its lowest side, somewhat flattened above, contracted and 

 having two pits without on each side towards its base, 

 again dilated as it covers the germen. Stamens didyna- 

 mous ; filaments distant, hairy near the base, adhering to the 

 corolla nearly as far as the throat, there suddenly bent, the 

 longer at right angles, the shorter at an angle of about 45°. 

 The longer filaments projecting from each a clavate tooth 

 at this angle, pass horizontally round the throat of the 

 corolla, and meet under the stigma ; the shorter having a 

 much smaller tooth at the angle, pass obliquely upwards to 

 the style, and meet below the others. Anthers bilobular, 

 divaricating, lilac, at first free, afterwards cohering in pairs, 

 and bursting along the front. Stigma exserted, of two 

 ovate, subacute, diverging plates, the lower rather the 

 largest. Style glabrous, filiform, slightly flattened near the 

 stigma, as well as the filaments colourless, marcescent. 

 Germen green, conical, somewhat furrowed in the sides, 

 ovules very numerous, attached to a large, central recep- 

 tacle. Capsule ovate, tumid, tipped by the persisting base 

 of the style, bilocular, bivalvular, valves entire, dissepiment 

 parallel to the valves, seeds very numerous, ovate, dotted. 



Seeds of this very pretty plant * were sent from New 

 Holland by Mr. Eraser last year, and communicated to 

 the Botanic Garden, Edinburgh, both directly from himself 

 and by Sir Thomas Brisbane, in October and November. 

 They were marked " Ruellia, sp. nov. from the banks of 

 the Hiver Brisbane, Moreton Bay." Graham. 



* I think it scarcely accords sufficiently with the name or character of 

 Mr. Brown's T. scabra, to warrant its being with certainty united to that 



species. H,
