Cult. The hardy, herbaceous, perennial species of Veronica 

 are generally grown in flower borders, for which they are well 

 fitted on account of their beauty ; they are of the most easy 

 culture, and are readily increased by division at the root. 

 The annual kinds, having rather a weed-like appearance, are 

 only grown in botanical gardens ; the seeds of them only re- 

 quire to be sown in the open ground. The species natives of 

 . Holland. Van Diemen's Land, and New Zealand, being 

 rather tender, require to be treated as greenhouse plants ; the 

 shrubby kinds of these are propagated by cuttings ; the others 

 by divisions of the root.

LIK. SYST. Diandria, Monogynia. Calyx of 2 sepals, com- 

 pressedly closed ; sepals cordate, serrated, -lobed. Corolla 

 subrotate, 4-cleft ; the 2 opposite lobes the smallest. Stamens 

 2, shorter than the corolla, without any rudiments of sterile 

 ones ; anthers didymous. Stigma simple. Capsule roundish, 

 compressed, obcordate, 2-celled, 4-valved, 4-seeded. An an- 

 nual plant, with the habit of the species of Veronica belonging 

 to section Cochlidiosperma. Stems many, subdichotomously 

 branched, decumbent, nearly terete, furnished with 2 rows of 

 spreading hairs. Leaves cordate-ovate, bluntly serrated, pale 

 green, hairy. Pedicels solitary, axillary, declinate while bear- 

 ing the fruit, about equal in length to the leaves, or exceeding 

 them a little. Calyx downy, finely ciliated. Corolla pale blue, 

 much shorter than the calyx. Capsule inclosed, ex Bieb. ; 

 glabrous, ex Lehm. Seeds large, wrinkled, black. Navicular.
