Hipareo : Ixmiquilpan, mountain slopes, C. A. Purpus, no. 1411 a; 
Sierra de Pachuca, altitude 2897 m., C. G. Pringle, no. 7618, in part; 
hills near Julanaciugo, C. G. Pringle, no. 13,278. Pursia: Mt. Orizaba, 
tose & Hay, no. 5686. San Luis Porost: in montibus San Miguelito, 
J. G. Schaffner, no. 741; Parry & Palmer, no. 691. Coanutia: north- 
east side of Mt. Colima, P. Goldsmith, no. 80. Seemann’s plant from 
northwest Mexico is doubtfully included. These specimens probably 
represent an aggregate of perhaps two or more species which it seems 
impossible with the present knowledge to segregate. The line between 
this species and the preceding is not very clear. It is somewhat 
doubtful in the light of present investigation how much weight is to be 
placed on the form of the lower lip of the corolla. The above specimens 
are all characterized by a lower lip with three teeth incurving in age, 
separated by a broad infolding sinus, so that when it is spread open the 
teeth are quite separated. C. scorzonerifolia has the teeth of the lower 
lip rather close and the sinus marked by smaller teeth. The indumen- 
tum of C. glandulosa is in general pilose, but there is also present a 
close glandular pubescence or almost puberulence, the glands under & 
lens appearing shortly and finely stipitate. The leaves are somewhat 
variable, though the typical specimens in each species have rather long 
acuminate leaves. Some specimens included among the above have 
obtuse leaves not at all acuminate. 5 
25. C.cryptandra, n. sp., pilosa et hirsuti-scabrida, striata ; foliis 
veiny leaves, coarse and rough pubescence, and in having the lower 
of the corolla with three instead of. five teeth. It is also related to © 
lithospermoides, but the bracts are much larger, almost completely 
concealing the flowers.
