Calyx (small or medium) divided nearly to the base; segments 5 
(or very rarely 4), linear or linear-lanceolate. Corolla 2-lipped, 
nearly always 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 ellipsoid, 
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,
