and Monghyr by Dr. Hamilton ; and near Deyre by Dr. 

 Wallich, to whom the Royal Botanical Gardens of Kew 

 are indebted for a living plant. It requires a stove heat,, 

 and with that treatment blooms readily in a pot, during the 

 summer months, when its flowers render it ornamental. It 

 belongs to the second tribe of Nees von Esenbecr's 

 Acanthace^ which he calls Ruellieje, and constitutes a 

 Genus, of which the present is the only species yet known 

 to us. 



Descr. With us it forms an upright shrub, with woody 

 articulated stems, the joints short. Leaves opposite, on 

 short petioles, ovate, acute, serrated, nearly glabrous, 

 strongly veined, dark green. Peduncles axillary, one- or 

 few-flowered, in the latter case racemose, always shorter 

 than the leaves, bearing immediately below the flower, and 

 concealing the calyx, a pair of large, cordate, leafy and 

 strongly veined, entire, bracteas. Calyx cut almost to the 

 base into five linear-subulate, erect, downy segments, of 

 which one is a little longer and broader than the rest. 

 Corolla large, between funnel-shaped and campanulate; the 

 tube enlarged upwards, white ; the limb of five spreading, 

 obovate, crenulate lobes, white, within streaked with red- 

 dish hairs, and in the lower faux clothed with scattered 

 hairs. Stamens four, didynamous. Anthers ovate, each 

 lobe with an awn at the base. Germen ovate, seated, as it 

 were, on a glandular disk, and having a protuberance on 

 each side. Style longer than the tube of the corolla. Stigma 

 of two subulate segments.
