 leafy, the fifth upper one much narrower and more pointed. Corolla 

 beautifully spotted inside, with 4 short lobes, the lowest about twice 

 the length of the others and hairy inside.

IX. VERONICA, SPEEDWELL. 



Herbs (or shrubs in a few exotic species), with opposite stem-leaves, 

 and small flowers, usually blue or white, sometimes arranged in spikes 

 or racemes, or in the axils of alternate floral leaves. Calyx 4- or 5- 

 cleft. Corolla with a very short tube, the limb rotate, deeply 4-cleft, 

 the lower segment the narrowest. Stamens 2. Capsule more or less 

 flattened laterally (at right angles to the partition), and opening round 

 the edges in 2 valves. Seeds few. 



A numerous genus in the northern hemisphere, with a few species 

 spreading into the tropics and far into the southern hemisphere, 

 whilst a few are peculiar to Australia, and very many to New Zealand, 

 where the genus forms a dominant feature throughout the island. 

 Among the latter the V. speciosa, salicifolia, Lindleyana, and other 

 shrubby or half-shrubby ones, are much cultivated in our gardens. 

 Several species occasionally have two forms of flowers, one large 

 and blue, the other smaller and pinkish.
