cent, its lobes narrowly lanceolate, elongated, usually 
with small short rounded auricles at the sinuses; cor- 
olla-tube about 5” long, 1-14” thick, the lobes of its 
larger lip broadly ovate, glabrous; larger anthers mi-

glandular; peduncles very short, sometimes with a pair of

lobes subulate, the sinuses not appendaged; corolla-tube 
5-6” long, 1-14” thick, about twice as long as the calyx- 
lobes; larger lip of the corolla pubescent within at the 
base, its lobes ovate, acutish; anthers all bearded at the tip.
