EASTWOOD. — MEXICAN SPECIES OF CASTILLEJA. 575 



specimen from the same region, C. V. Hartman, no. 150 (Lumholtz 

 Exped.), which may be this species. C. nervata resembles C. aspera 

 in the tuberculate-rugose sac-like lower lip of the corolla, but differs in 

 having the segments of the calyx quite entire and in the glandular 

 pubescence. The flowers are smaller and the capsules less ovoid. The 

 strongly nerved leaves suggest C. Uthospermoides, but otherwise it is 

 quite different.

 bracteis oblongis apice rotundatis vel acutis coccineis puberulis flores 

 subaequantibus, basi pilosis 2-2.5 cm. longis 5-8 mm. latis ; calyce fisso

 in part (type, in hb. Gray). As in C. Conzattii, to which this species 

 is related, the flower after anthesis has a tendency to curve outward 

 above the capsule.
