almost exactly linear. Peduncles an inch or more long, 
bearing, above the middle, two opposite leaves or bracteas, 
and generally one, sometimes two flowers. Calyx very 
small in proportion to the size of the corolla, deeply cut 
into five linear-subulate, narrow, spreading, or recurved 
segments. Corolla an inch and a half long, red-purple, 
much paler in bud. Tube narrow at the base, gradually 
expanding upwards ; limb two-lipped, upper lip two-, lower 
three-lobed ; lobes very obtuse, spreading. Stamens 1n- 
serted below the middle of the tube, four didynamous, and 
a fifth sterile filament, quite glabrous. Anthers cordate, 
deep purple. Style rather longer than the sterile filament.
