Discovered by Mr. Gardner on the Organ Mountains of 

 Brazil in March, 1841, growing two to four feet high, in 

 rocky places; and raised from seeds, sent over to Mr, 

 Mack.ay, at the College Botanic Garden, Dublin, where it 

 produced its handsome flowers in July, 1844. It is very 

 distinct from any species hitherto described, and remark- 

 able for the thick and fleshy leaves, shaped not unlike 

 those of the Elm, pale-coloured, and with prominent nerves 

 beneath. 



Descr. Stems erect, herbaceous, rounded, quite gla- 

 brous, branched. Leaves opposite, very thick and fleshy, 

 petiolate, elliptical, acute or slightly acuminate at both ex- 

 tremities, strongly serrated, obliquely nerved, very minutely 

 pubescent when seen under a lens. Petiole half an inch or 

 more long, terete, flattened above. Peduncles axillary, 

 solitary, single-flowered, erect, slender, almost as long as 

 the leaf, glabrous. Calyx five-partite; the tube short, 

 united with the base only of the ovary, five-angled : seg- 

 ments subulato- lanceolate, spreading, entire, glabrous. 

 Corolla tubular, a little curved, slightly widening upwards, 

 subpubescent : limb of five short, obtuse, spreading lobes. 

 Stamens four, didynamous, inserted at the base of the co- 

 rolla, and equal in length with the tube, having a small, 

 subulate scale, or fifth abortive stamen, between them. 

 Germen ovate, hairy, as well as the long style, surrounded 

 by a glandular disc, or ring, with five nearly equal, obtuse, 

 erect teeth. Stigma obtuse.
