Gmelin speaks of a variety with flesh-coloured flowers, 
and of another with white flowers, 
Stems simple, square, ascending, six inches high, rough 
with reflexed hairs at the angles, Leaves oblong, obtuse, 
wavy, 3-nerved, stalked, shorter than the joints, beneath 
pubescent. Flowers in twin 8-flowered whorls, spiked, 
somewhat nodding, shorter than the leaf-like bracteze. 
Calyx bowed, purple, funnel-shaped, covered with erect 
hairs, 5-toothed ; the four lower teeth subulate and acute, 
the upper very large, transversely ovate, apiculate. Corolla 
bright sky-blue, twice as long as the calyx, slightly pubescent ; 
the throat inflated, compressed, the helmet vaulted, two- 
lobed; lobes rounded. Lip with the lateral divisions small, 
obtuse, spreading, dotted at the base with a deeper colour; 
the intermediate one larger, reniform, emarginate, with a 
dotted disk. Stamens ascending, pressed against the helmet, 
didynamous; the lower pair shortest, coming up as high as 
the base of the helmet; the upper pair a little shorter than 
the helmet. Ovaria 4, very small, inserted in a fleshy disk. 
Style filiform. Stigma exserted, 2-lobed; the lobes at 
length curved backwards, with respect to the axis of the 
flower anterior and posterior.
