Calyx (small or medium) divided nearly to the base ; segments o 

 (or very rarely 4), linear or linear-lanceolate. Corolla 2-lipped, 

 nearly alw^ays hairy without; tube not (or scarcely) longer than the 

 limb ; anticous lip 3-lobed ; posticous lip entire or shortly 2-lobed ; 

 palate often marked by spots or transverse wrinkles. Stamens 2 ; one 

 anther-cell distinctly below the other, definitely tailed ; pollen elHpsoid, 

 with 2 or 3 longitudinal smooth areas containing stopples, continued to 

 the pole or not, with longitudinal rows of tubercles often reduced to 

 granular patches or obsolete. Ovary with 2 (or 1) ovules in each cell ; 

 style linear, usually more or less hairy in the lower half ; branches 2, 

 minute, subequal. Capsule 4-seeded , stalk solid, usually short, not 

 slender: placenta not rising from the base elasticolly ; seeds rough or
