superior anthers connate, obtuse, empty ; the rest all acute and 
fertile. Upper lobe of style very short ; lower one longer, stig- 
matiferous almost from the base. Achenia dry, large, somewhat 
inflatedly compressed, smooth. The want of the upper lobe of 
the calyx is peculiar to this genus.

Li. syst. Didynàmia, Gymnospérmia, Calyx tubularly cam- 
panulate, about 5-nerved, with an equal or often oblique mouth ; 
teeth 5, nearly equal, or the upper ones are longer, subulate at

a hairy ring inside; limb bilabiate; upper lip ovate or oblong, 
somewhat arched or galeate, for the most part narrowed at the 
base; throat dilated ; lateral lobes truncate at the margins of 
the throat, rarely oblong, furnished with a tooth-formed appen- 
dage or mutic ; middle lobe broad, emarginate, contracted at the 
base, substipitate. Stamens 4, didynamous, lower pair the long- 
est; anthers approximate by pairs, 2-celled : cells at length di- 
varicate, oblong, hairy outside or naked. Style about equally

doubly or deeply toothed; floral leaves almost similar to the 
rest : upper ones smaller and more sessile ; all exceeding the ca-
