altitude 3350 m., H. EF. Seaton, no. 208. San Luts Porost: altitude

Canoas, C. G. Pringle, no. 3066. Srate or Mexico: Nevada de To- 
luca, about timber-line, altitude 4000 m., C. G. Pringle, no. 4225; 
Sierra de Ajusco, J. W. Harshberger, no. 123a. Coanuria: Sierra de 
Parras, C. A. Purpus, no. 1051; Levios, 67 km. east of Saltillo, 
E. Palmer, no. 2026, coll. of 1880. Nurvo Leon: near Monterey,

smith, no. 80a. Duranao: Otinapa, EZ. Palmer, no. 367, coll. of 1906, 
in part. Mexico without locality: Dr. J. Gregg, no. 407. The follow- 
ing have been examined from hb. U. 8S. Nat. Mus. — Mount Orizaba, 
E. W. Nelson, no. 282, Rose & Hay, no. 5741. Tamavurpas: moun- 
tains near Miquihuana, altitude 2135-2745 m., EZ. 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.
