of the species given below. As the seeds are not known, the 

 species may not belong to the group with squamellate seeds. 



7. Delphinium Carolinianum Walt. Car. 155. 1788 



D. azureiun Michx. Fl. Bor. Am. i : 314. 1803. 



D. Carolinianum is confined to the South, ranging from North 

 Carolina, or perhaps Virginia, to Missouri and south to Florida, 

 Lousiana and Arkansas. It is characterized by the slender habit, 

 the small deep blue flowers, the long straight narrow raceme, the 

 slender and slightly curved and usually horizontal spur.* The 

 seeds are quite different from those of the related species, being 

 smaller, only 1.5 mm. long, with broad wing-margins on the 

 angles and only slightly squamellate on the sides. The following 

 specimens are in the herbaria of the New York Botanical Garden 

 and Columbia University.

The flowers are similar to the preceding, but the plant is taller, 

 often over a meter high, with slender lax branches. The most 

 striking difference, however, is found in the seeds. These are 

 scarcely angled at all, but with exceedingly strong transverse 

 lamellae and over 2 mm. long. It is a species confined to the 

 Gulf Region. 



Texas : Driimmond. 



Louisiana : Alexandria, and Red River, Hale.
