solitary, or many, aggregate, drooping, violaceous, greenish-yel-

Doubtful Gloxinia. Shrub. 
Cult. Gloxinia is a genus of splendid plants, and great 
favourites with gardeners. A light rich soil, or a mixture of 
sand, loam, and peat, suits them well. G. maculdta is increased 
by dividing at the root; and it should be kept free from suck-
