 flowers in short terminal racemes and in the axils of the upper leaves : pedicels like 

 the leaves or bracts usually verticillate : corolla scarlet, hardly an inch long ; the 

 tube cylindrical except the gibbous base, twice or thrice the length of the narrowly 

 lanceolate sepals, 3 or 4 times the length of the short lips : stigma entire or emargi-
