CHARACTER OF THE GENUS, RuELLIA. Catyx five-cleft, almost 
or quite to the bottom, the divisions equal or not very unequal. Cor- 
OLLA funnel-shaped, the limb spreading, of five nearly equal round 
blunt divisions. Stamens four, included in the tube, didynamous; 
anthers oblong, the cells parallel with or without a point at the base. 
Ovary two-celled, each cell containing three or four ovules. STYLE 
simple, with a small tooth on the upper side below the subulate stig- 
mate. Capsules oblong, two-celled, six-or eight-seeded, splitting across 
the cells into two valves each bearing a portion of the dissepiment 
along the centre. SrEps supported on retinacula. 
DESCRIPTION OF THE Species, Ruettia AustRais. STEM erect 
or somewhat spreading, much branched, growing to near a foot in 
height, clothed with soft shite Suhcating hairs. Leaves stalked, vary- 
ing ies oval to lanceolate, entire or with a few coarse teeth, blunt or 
scarcely sharp, contracted at the base, hairy on both sides, the upper 
tesa nienaiied into bracts. FLowers axillary, sometimes soli- 
tary in the axils of the stem leaves, more frequently by the conver- 
sion of the leaves into bracts and their being crowded together, 
forming a short Jeafy spike at the ends of the branches, or placed three 
together in the axils, accompanied by a pair of bracts. These Bracts 
only differ from the other leaves by being smaller and much narrower. 
CaLyx nearly sessile, of five linear or subulate divisions, sometimes 
most equal to each other, but more frequently one or two are dis-
