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. lithospermoides, but otherwise it is 
quite different.
