Gex. Char. Calyx (fig. 1.) inferior, of 1 sepal, compressed, 
somewhat inflated, rounded, bladdery, veiny, permanent; the mar- 
gin in 4 nearly equal, acute, deep teeth, broad at their base. Corolla 
(fig. 3.) ringent, nearly closed ; tube almost cylindrical, the length 
of the calyx; upper lip narrowest, hooded, compressed, slightly 
cloven ; lower broadest, expanded, divided half way into 3 blunt 
lobes, the middle one rather the largest. Filaments (fig. 4.) 4, two 
longer than the other two, thread-shaped, shorter than the upper 
lip of the corolla, and concealed within it. Anthers incumbent, 
2-lobed, hairy, not prominent. Germen (see fig. 2.) egg-shaped, 
compressed, with a channel on each side. Style (see fig. 2.) 
thread-shaped, curved, somewhat longer than the stamens. Stigma 
deflexed, blunt. Capsule (fig. 5.) roundish egg-shaped, compressed, 
blunt, with a small point, of 2 cells, and 2 valves separating at the 
margin ; partitions transverse, combined, narrow. Seeds several, 
inversely egg-shaped, compressed, imbricated, curved downwards, 
more or less bordered. 
The 4-cleft, inflated calyx ; the capsule of 2 cells ; and the com- 
pressed, bordered, imbricated seeds; will distinguish this from 
other genera in the same class and order.

upper lip of the corolla, which is very remarkable in the exotic Ithinanthus Ete-
