and with the same ashy pubescence. Aah channeled, 1-2 ft. 
high and ending in a bractless raceme 4-6 inches long. Leaven 
opposite, oval-ovate, cuneate into the filiform petiole which is 4 
as long as the blade, the whole 2-4 inches long, dissected nearly 
half way to the midrib into 4-11 oblong and apiculate lobes about 
1 cm. long, occasional lobes again cut. Flowers 1cm, long. Ca. 
lyx tube linear, clavate, the subulate teeth about 1 mm. long, 
Corolla exserted, nearly as long as calyx tube, rather labiate and 
4mm. wide at tip, blue, Frust twice as wide as in dissecta and
