and copious watering during hot weather. The half-hardy species, like 

 V. speciosa, must be given slight protection in winter, turning them out 

 again about May. In the extreme South of England there are many 

 places where such species will do outside with little protection during the 

 winter; such, for instance, as is provided by planting them against a 

 south wall. Shrubby Veronicas are increased by cuttings taken at any 

 time from the young shoots. These should be inserted in pots of sandy 

 soil, and stood in a shady close place. The herbaceous perennials may 

 also be propagated in a similar fashion, but they are chiefly increased by 

 division of the plant. The annuals come readily from seed sown early 

 in spring.

GLOXINIAS 



Natural Order Gesneracej^.. Genera Gloxinia and Sinningia 



Gloxinia (named in honour of Benj. P. Gloxin, of Colmar, an eigliteenth 

 century botanical author). A genus of about half a dozen species of 

 greenhouse herbs, with thick- textured opposite leaves, stalked, and of 

 rich colours; and drooping, bell-shaped, tubular flowers. The border 

 of the corolla is oblique, the upper lip two-lobed, and shorter than the 

 three-lobed lower lip. The ovary is below (inferior to) the corolla, and 

 between the two there is a complete circle of glands. The stigma is 

 rounded and hollowed out. The species are natives of Tropical 

 America. 



SiNNiXGiA (named in honour of William Sinning, one-time gardener 

 to the University of Bonn). A genus of about sixteen species of green- 

 house herbs, very similar to Gloxinia, but diflering in the facts that the 

 ovary is only semi-inferior, and that the circle of glands surrounding the 

 ovary is broken into a series of Ave distinct glands. They are natives 

 of Brazil.
