FROM THE COROLLA. 45] 
The X indicating the position of the petalodes. 
A still more singular case is that of a variety of the 
Gloxinia, described originally by Professor Edouard 
Morren,! but which is now becoming common in 
English gardens. When first observed these flowers 

Fic. 213.—Gloxinia, with supernumerary segments on the outside of 
the true corolla. 
were observed to produce petaloid segments outside 
the ordinary corolla, and partially adherent to (or 
rather, not completely separated from it) much as in 
the azalea before mentioned, the outer surface being 
brightly coloured, like the inner surface of the corolla 
in ordinary gloxinias. Being encouraged and tended 
by gardeners, in course of time, instead of a series of 
petalodes, more or less distinct from one another, a 
second corolla or “catacorolla’’ was formed outside 
the primary one, so that a hose in hose flower was 
produced, but, in this case, the supplementary flower 
was formed on the outside and not within the ordinary 
corolla. Moreover, the disposition of the colour was 
reversed, for in the outermost corolla the richest hues 
were on the outer surface, while in the inner or true 
corolla they were on the inside.
