578 PROCEEDINGS OF THE AMERICAN ACADEMY. 



Hidalgo: 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. Puebla: Mt. Orizaba, 

 Rose it- Hay, no. 5686. San Luis Potosi: in montibus San Miguelito, 

 J. G. Schaffner, no. 741 ; Parry & Palmer, no. 691. Coahuila: 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 a 

 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. 



25. C cryptandra, n. sp., pilosa et hirsuti-scabrida, striata ; foliis 

 superioribus ovatis acuminatis integris 3-5-nerviis, apice obtusis, basi 

 cordato-amplexicaulibus, nerviis hispido-scabridis ; spicis coccineis, 

 floribus confertis breviter pedicellatis, bracteis obovatis coloratis flores 

 superantibus, 3 cm. longis, 1-1.5 cm. latis integris apice rotundatis ; 

 calyce fisso 1 cm., 2.5 cm. longo, laciniis obtuse bilobatis 4 mm. longis, 

 glandulari-pilosis ; galea paulo calycem superanti dorso pilosa et gland- 

 ulosa ; stylo curvato exserto, stigmate clavato ; capsula compressa 

 ovato-acuminata. — Colima : Cuchilla, northeast side of Volcano 

 Colima, 22 July, 1905, P. Goldsmith, no. 76 (type, in hb. Gray). — This 

 is a showy species related to C. scorzonerifolia, differing in its more 

 veiny leaves, coarse and rough pubescence, and in having the lower lip 

 of the corolla with three instead of five teeth. It is also related to C. 

 lithospermoides, but the bracts are much larger, almost completely 

 concealing the flowers. 



26. C. lithospermoides HBK., caule recto simplici piloso-hispido ; 

 foliis lanceolato-linearibus, apice angustatis et obtusis, integris valde 

 trinerviis piloso-hispidis ca. 5-7 mm. latis 3-6 cm. longis; floribus spi- 

 catis sessilibus; bracteis apice dilatatis rubicundis flores excedentibus ; 

 calycis segmentis bilobatis, lobis rotundatis ; corolla albida vix calyce
