 E. W. Nelson, no. 282, Rose £ Hay, no. 5741. Tamaulipas: moun 

 tains near Miquihuana, altitude 2135-2745 in., E. W. Nelson, no 

 4485. This is a showy plant, distinguished from allied species by the 

 pilose pubescence (somewhat glandular only on the inflorescence) and 

 by the five-toothed lower lip of the corolla. The species may prove 

 to be an aggregate when more fully understood. The forms with 

 strictly acuminate capsules do not seem exactly similar to those with 

 capsules subtruncate to acute, but the material has not been sufficient 

 to warrant a division.
