BEGONIA., 41 
of April, when they may be repotted in a rich soil. Use 
pots sufficiently large to accommodate the tuber without 
crowding the roots. If wanted for show plants, the 
pots must be quite large. For a vigorous two-year-old 
plant a ten inch pot will be necessary. If the plants 
are to be transferred to the border, a six-inch pot will 
be sufficiently large to accommodate them until they are 
planted out. For the greenhouse or conservatory, the 
tubers should be started as soon as they show signs of 
growth, which will be early in February. 
Like all other florists’ flowers, the varieties of the 
Tuberous Begonias haye been, by crossing and recross- 
ing, increased to a wonderful extent, so that the named 
varieties first noticed have been lost sight of. The fol- 
lowing species are parents of the now popular sorts, or 
classes, both of the double and single varieties. 
B. boliviensis.—Introduced by Messrs. Veitch & 
Son, London, in 1864. It has small drooping flowers, 
of a bright cinnabar-scarlet color. 
B. Pearcei.—So called in honor of Mr. Pearce, 
the collector for Messrs. Veitch & Son; flowers about 
one inch to one and one-quarter inches across, clear 
yellow ; foliage beautifully marbled. 
B. Veitchii.—This was found in Peru at an eleva- 
tion of 12,500 feet, and is one of the most beautiful of 
the species. Its flowers are of an immense size, of an 
inimitable, vivid vermillion-cinnabar red. 
B. roszflora.—A species of but little value, with 
flowers of a pale red color. 
B. Davisii.—A very dwarf-growing species, with 
scarlet flowers, and smooth glossy foliage. This has 
proved of great value to the hybridists, who have, by 
judicious crossing of this species with other strains 
derived from the Boliviensis and Veitchii types, pro- 
duced a vast number of varieties, both single and double 
flowered, possessing the characteristics of a remarkably
