198 SCROPHULARINEJ3. [Veronica. 



Near Grey Abbey ; Mr. Templeton. Near Bantry ; Mr. J. 

 Ztrummond. Fl. June, July. T. Smaller than the last. Vesi- 

 cles mixed with the leaves, which are glabrous at the margin. Flowers 

 very pale yellow and small. Spur scarcely any. Lower lip almost 

 plane ; palate scarcely closing the mouth, not projecting beyond the lip. 

 " The British species of this genus are all aquatics ; and the roots, 

 stems, and even leaves are furnished with numerous membranaceous, 

 reticulated vesicles, which according to Hayne, are filled with water, 

 till it is necessary the plant should rise to the surface, and expand its 

 blossoms above the fluid. The vesicles are then found to contain air 

 only, by aid of which the plant floats : this air again in the autumn 

 gives place to water, and the plant descends to ripen its seeds at the 

 bottom of the water. Aquatic insects arc often seen in these bladders," 

 Hooker.
