Calyx 5-partite; segments linear, sometimes spathulate, usually 
unequal. Corolla 2-lipped, conspicuous; tube comparatively short ; 
upper lip of two petals forming a hood ; lower of three petals more or 
less saccate towards the base. Stamens 2, their anthers protected by the 
hood of the corolla ; ventral pair of stamens represented by staminodes ; 
filaments inserted into the tube of the corolla to which they are con- 
nected for some distance. Pollen with longitudinal ribs, sometimes 
spiny. Stigma projecting beyond the hood ; posterior lobe reduced to 
@ very small tooth. Ovary with many ovules. Capsule linear, its 
valves grooved on the back, 2-celled. Seeds many, flattened; retina- 
cula present.—Herbs reaching 10 ft. in height, with large leaves, the 
upper and often the lower side of which, owing to the presence of 
crystals, appears as if marked with white scratches. Flowers of various 
shades of purple.—Belantheria, Nees in DC. Prod. xi. 96. Leucorhaphis,
