Gen. Char. Calyx (fig. 1.) inferior, of 1 sepal, tubular, cylin- 

 drical, with 5 prominent angles, and 5 sharp, spreading teeth, 

 permanent. Corolla (fig. 2.) ringent ; not above twice the length 

 of the calyx ; tube short, cylindrical, narrow; throat longish, but 

 little dilated ; limb spreading ; upper lip (fig. 3.) longest, concave, 

 protuberant, rounded and undivided at the summit, covered with 

 soft hairs ; lower lip, (fig. 4.) reflexed, in 3 deep, spear-shaped, 

 undivided, smooth, nearly equal lobes. Filaments (figs. 3 & 4.) 4, 

 2 longer than the other 2, much shorter than the corolla, sheltered 

 under the upper lip. Anthers (see fig. 5.) roundish-oblong, at- 

 tached by the back, incumbent, clothed in an early state with 

 minute, globular, solid, shining granulations, and soon bursting in 

 front into 2 cells. Germcn (fig. 6.) 4-lobed, abrupt. Style (fig. 6.) 

 thread-shaped, incurved. Stigma of 2 pointed, spreading seg- 

 ments. Seeds (fig. 7.) 4, quadrangular, abrupt, hairy, in the tube 

 of the slightly hardened, strongly veined calyx. 



Distinguished from other genera in the same class and order, by 

 the very hairy upper lip of the corolla, and the hard shining granu- 

 lations with which the anthers are besprinkled. 



One species British.
