Gen. Char. Calyx (fig. 1.) inferior, permanent, of 1 sepal, in 
5 deep, oblong segments ; the two lower of which are most distant 
from each other. Corolla (fig. 2.) of 1 petal, personate ; tube 
(fig. 2, a.) oblong, inflated, gibbous at the base (fig. 2, b.) , without 
a spur ; limb 2-lipped ; upper lip (fig. 2, c.) cloven, reflexed at 
the sides ; lower lip (fig. 2,d.) obtuse, 3-lobed, with a projecting 
palate, closing the mouth, and hollow underneath. Filaments (f. 3.) 
4, 2 longer than the other 2, concealed under the upper lip of the 
corolla. Anthers (see fig. 4.) converging. Germen (fig. 6.) round- 
ish, or egg-shaped. Style (see figs. 3 — 6.) thread-shaped. Stigma 
blunt. Capsule (fig. 7.) roundish, or oval, blunt, of 2 cells (see 
fig. 8.), oblique at the base, opening by 3 pores at the apex. Seeds 
numerous, attached to an oblong, cylindrical receptacle ( placenta ) 
in the middle of the partition ( dissepiment). 
Distinguished from other genera, in the same class and order, 
by the 5-cleft calyx ; the personate corolla, gibbous at the base in 
front, its mouth closed with a projecting palate ; and the 2-celled, 
many-seeded capsule, unequal at the base, and opening by 3 small 
holes at the apex. — The want of a spur will distinguish this genus 
from that of Linaria, see folio 23. 
Two species British.
