 deeper than the posterior; the long upper lip acutely 4-toothed or 2-cleft and 

 the lobes 2-toothed: corolla 4-5 cm. long; the narrow, falcate, and much ex- 

 serted galea as long as the tube. (C. cognata Greene, PL Baker. 3: 22. 1901;

 laciniate into narrow segments: bracts green, similar to the upper leaves, 

 shorter than the sessile flowers: calyx deeper cleft on the lower side than on 

 the upper, the lobes linear-lanceolate, acute: corolla yellowish, 4 cm. long, 

 the upper lip about twice as long as the lower, the lobes of the latter linear:

 2-4 cm. long, dark green, variously cleft, the lower mostly pinnately, the 

 divaricate lobes linear or broader, sometimes again 1-3-cleft, on either side: 

 bracts bright red, more freely cleft than the leaves: calyx cleft nearly to the

 exceeding the tube, slender, truncate or with a short tooth at apex, obscurely
