downy ; leaves ovate-oblong, nearly entire, downy ; pedicels 

 axillary, solitary, much longer than the flowers ; segments of 

 corolla acutish, entire ; calyx downy, about equal in length to 

 the corolla. . H. Native of America, in the vicinity of the

7 C. SPARSIFLORA (Fisch. et Meyer, cat. sem. hort. petrop. 

 2d. 1836.) diffuse ; leaves all opposite ; flowers solitary ; pedi- 

 cels a little longer than the calyx; capsule globose. 0. H. 

 Native of California, about the Russian colony, Ross. Smooth- 

 ish, much branched. Stems and branches filiform. Leaves all, 

 or only the upper ones opposite, on which account it is distin- 

 guished from the other species. The flowers are solitary, rarely 

 opposite, of a size intermediate between those of C. grandiflbra 

 and C. parviflbra. Corolla pale violet : lateral segments of the 

 lower lip deep purple.

Cult. All the species being showy, they are well fitted for 

 decorating flower borders, or to be grown in beds or large 

 patches. The seeds only require to be sown where the plants 

 are intended to remain in March or April.
