trorsely) in aestivation ; they diflfer also in the position of the stamens, which are placed 



in the upper portion of the tube (not in the lower), and in the peculiar form of its disk, 



which, though distinct, is easily overlooked.

A species certainly dififerent from Vahl's plant, as its leaves are not undulated, its 

 sepals unequal, and the corolla pubescent in the throat, and its leaves are in very 

 unequal pairs. It is a shrub with subflexuous dichotomous branches, the branchlets 

 compressed, "with remote axils. The leaves are oblong, acute at the base, constricted at 

 the summit by an obtuse linear acumen, firmly chartaceous, the margins somewhat 

 revolute, of a very pale green above, opake, with immersed patent nerves arcuately con- 

 joined within the margin, yellow and opake below, with immersed nerves, the unequal 

 pairs being 4 and 2 in. long, 7 and 4 lines broad, on channelled petioles 3 and 1^ line long : 

 in the upper axils they are somewhat smaller, and in the same proportions. Meyer says 

 the inflorescence is terminal on a short peduncle, bearing 3 or 4 flowers on short pedicels, 

 each with a basal ovate obtuse concave bracteole ; sepals unequal ; corolla 1 in. long ; 

 tube cylindrical, ventricose below the mouth, which is pubescent; segments oblique, 

 linear oblong, obtuse ; anthers included below the mouth of the tube ; disk not seen 

 (said to be none) ; ovaries conical ; style simple ; clavuncle incrassated, with a basal 

 membranaceous appendage. These characters are quite those of Anartia.
