Veronica hwnifusa, or Thyme-leaved Speedwell, may be 

 recognized by its decumbent branching stems ; that is to say, 

 the stems are curved near the base and lie partly on the 

 ground, rooting where the joints touch the earth. Usually 

 these stems grow in pairs and bear at their upper ends spikes 

 of pale gray-blue blossoms striped with dark blue, the tiny 

 flowers also growing at close intervals lower down on the 

 stalks. The small oblong leaves grow in opposite pairs. 

 Occasionally the flowers are white. 



Veronica americana } or Water Speedwell, is perennial by 

 stolons, or leafy shoots developed in the autumn. The

 branched. The leaves are lanceolate, acute, serrulate or 

 entire and short-petioled. The peduncled racemes are borne 

 in the axils of the leaves, and the flowers are pale blue with 

 purplish stripes.
