 laterally 0.5 mm. or less or its rounded lobes wholly united into a rounded-truncate tip; corolla 

 about 15 mm. long, its galea 7 mm. long, puberulent distally dorsally, with pale narrow thin 

 margins, its lower lip 2 mm. long, dark green, rudimentary, appressed; capsule 11 mm. long.

Plant perennial, sparsely pilose with short and weak glandless hairs below the pubescent 

 inflorescence, the calyces lanuginous. Stems herbaceous, slender, much-branched, 5-6 dm. tall or 

 more; leaves lanceolate, with 1 or 2 pairs of lance-linear lobes; bracts green, with rounded 

 segments ; calyx pale, 16-19 mm. long, cleft laterally more deeply than medianly, its tube 8-10 

 mm. long, its upper lip 4-7 mm. long, cleft medianly 2-3 mm. into acute or obtuse lobes, its 

 lower lip 6-9 mm. long, wider and hardly cleft at the rounded apex; corolla 18 mm. long, its 

 galea 11 mm. long, yellow, pubescent dorsally, with wide pale thin margins, its lower lip 1.5 

 mm. long, yellowish, rudimentary, apparently concealed by the lower calyx-lip (the lanuginous
