- “Drscr. Stem herbaceous, four-sided, and, as well as the fo- 
liage, hoary with copious short hairs. Zeaves opposite, short- 
petiolate, cordato-ovate, crenato-serrate, shortly acuminate. Pe- 
duncles solitary, axillary in the upper leaves, longer than they, 
single-flowered. Flowers inclined, large. Calyx oblong; angu- 
lar, scarcely winged, downy, blunt at the base, two-lipped, up- 
per lip deeply bifid, lower lip trifid, segments acuminate. Co- 
yolla more than twice as long as the calyx, tube gibbous above. 
Corolla rich purple; upper lip entire, lower lip three-lobed, la- 
teral lobes very deep purple, middle lobe white, with a purple 
margin. Stamens and pistil included: their structure the same 
as that in 7. Asiatica. ‘
