opposite round ))v»bescent petioles, twice as long as itself. Leaves (8 

 inches long, 6^ broad) ovate, peltate, minutely glanduloso-pubescent, 

 strongly nerved, bullate, unequally crenato-dentate, concave and dark 

 above, paler below ; corymbs subradical. pedicels (2-24 inches long) erect, 

 very slender, glanduloso-hairy, opposite, decussating, rising from the axil 

 of a linear bractea. Flotvers deflected outwards. Calyx glanduloso-pubes- 

 cent, 5-cleft, tube fleshy, adherent, teeth subulate, connivent after the 

 corolla falls. Corolla {\\ inch long) tubular, curved, limb of five, sub- 

 equal, rounded, short, segments, of which the two upper are rather the 

 smallest, and least deeply divided. Stamens 4, perfect, slightly exserted ; 

 filaments glabrous ; anthers dark, rounded, 2-lobular, bursting along the 

 face of the cells, connective, rounded ; pollen yellow, granules minute, 

 one, sometimes two rudimental stamens on the ujjper side of the tube at 

 its base. Disk white, projecting on the upper side, emarginate. Germen 

 half immersed in the calyx tube, above this conical, slightly pubescent, 

 brown. Ovules numerous. Style nearly as long as the stamens, slightly 

 pubescent, colourless. Stigma bilobular, lobes short. 



This singular-looking species was received at the Botanic Garden, Edin- 

 burgh, from Berlin in 1834, and has flowered freely in the stove every 

 autumn since. 



I have not had the advantage of seeing the description of this species by 

 Martins, nor do I know where it is published.

Description Plant herbaceous, scandent by the petioles, with long 



slender branches, everywhere, excepting on the outside of the corolla, 

 finely glanduloso-pubescent. Leaves (1| inches broad, 2| long) opposite 

 below, alternate above, petiolate, heart-shaped, subacute, coarsely and 

 unequally toothed, of lively green above, paler below, 7-nerved, nerves 

 prominent below, channelled above, teeth mucronate. Petioles as long as 

 the leaves, grooved above. Pedxindes solitary, axillary, single-flowered, 

 erect, reaching beyond the middle of the leaf. Calyx 5-partite, segments 

 (I inch long, 5 lines broad) oblong, slightly cordate at the base, atte- 

 nuated and connivent at the apex, projecting outwards along their edges, 

 entire, slightly undulate, subequal, the lowest rather the shortest. Co- 

 rolla twice as long as the calyx, funnel-shaped, purplish-rose coloured, 

 obscurely dotted on its outside, but without pubescence ; tube white, es- 

 pecially on its lower side, flattish above, with two grooves below, dilated 

 and angular where it covers the germen ; limb 5-lobed, uppermost lobes 

 largest, subacute, reflected, slightly pubescent within, lowermost blunt, 

 erect, the middle one the smSlest, and from its base on each side pro- 

 ceeds to the origin of the longer stamens, an elevated line corresjwnding 

 to the groove on the outside, and covered with short erect coarse hairs, 

 yellow only towards the limb, and much less dense than in Lophospermum 

 erubescens. Stamens 4, didynamous, as long as the tube, from the base of 

 which they arise, and to which they are adherent till they pass the ger- 

 men, above which they are free, and hairy for a little way, higher up 

 glabrous, spiinkled with a few colourless glands only towards the an- 

 thers; anthers cream coloured, lobes diverging below, and bursting along 

 the face, pollen gi-anules minute. A minute tuft of hairs between the 

 shorter stamens, and a little below the part at which they become free, 

 is the rudimental condition of a fifth stamen. Pistil as long as the shorter 

 stamens ; germen small, conical, green, seated upon a yellowish obscurely 

 lobed glabrous disk ; style continuous, straight^ in contact with the up-
