 apex, with an acute acumen, copiously hirsute, or sometimes merely strigose along the veins, 

 the venation prominent beneath; flowers few, crowded and sessile in the axils; calyx and 

 hypanthium densely hirsute, the calyx-lobes linear-lanceolate, acute, 2-4 mm. long, finally 

 reflexed; corolla white, hirsute or strigose, the tube about 6 mm. long, the lobes narrowly
