Sandy soil, hills of western Arkansas, and eastern Oklahoma

Readily distinguished from C. verna Nutt., of the Ohio Valley, 

 by the following contrast: 



Corolla blue, the nearly white posterior lobes little shorter than 

 the shallo wly notched antero -laterals. Seeds 3 mm. long. Leaves 

 lanceolate-ovate, mostly obviously dilated proximally. Stem 

 and pedicels with lines of pubescence. C. verna. 



Corolla violet, the pale posterior lobes about two thirds the length 

 of the deeply notched antero-laterals. Seeds 1 mm. long. Leaves 

 oblong-lanceolate, not dilated at base. Stem and pedicels more 

 densely finely pubescent over entire surface. C. violacea.

 Type species, M. sernperflorens Ortega,^ of Mexico. 



1. Maurandya antirrhinlflora Humb. & Bonpl. 



Maurandya antirrhiniflora H. & B.; Willd., Hort. Berol. pi. 83. 1807. "Hab- 

 itat in Mexico." Description distinctive. 

 Antirrhinum maurandioides A. Gray, in Proc. Am. Acad. 7: 376. 1868. 

 Based upon Maurandya antirrhiniflora G. & B. 



Certainly closely akin to M. scandens (Cav.) Pers. [=M. sem- 

 perflorens Ort.], being nearly alike in habit, leaves, pedicels, sepals, 

 capsules and seeds, differing only in corolla. 1\\ M. scandens this is 

 two-ridged within on anterior side, apparently in the manner of 

 Mimulus, while the smaller corolla of M. antirrhiniflora has these 

 ridges developed distally into a palate. 



Corolla blue, the palate conspicuously raised, light-yellow. 

 Flowering from April to September and soon ripening fruit. 



Stony calcareous soil, river-bluffs and hills, lower Edwards Plateau 

 and through arid southern Texas, from Travis and Gillespie to 



8 Practically a re-description, with renaming, of listeria scandens Cav., Icon.
