102 DEVELOPMENT OF THE FLOWER. 
hemispherical, in the two others quadrispherical), the same 
spheroidity of the young grains on their escape, the same 
development of the folds, and when these appear complete, of 
amylacious granules, the same disappearance of the nucellar 
granular matter as the grains develope. 
Parent cells breaking upon pressure are divided into as. 
many cells as there are nucelles. 
In Lindenbergia the corolla is developed in precisely the 
same manner from a smooth shining disc, occupying the 
calyx: this body is precisely like that found in the axils of 
the very young leaves. The stamina are at first like all 
others, but as soon as they are quadrilocular, the cells appear 
to grow by their lower ends, thus becoming detached as it 
were from the filament. 
Corolla included in the calyx, green; tube equalling in 
length the lacineze, very fleshy. Pl. 39.— Fig. 3. d, thick- 
ened margin. 
Stamina nearly sessile; i. e. no filament, hypogynous; qua- 
drilocular cells occupied by a linear cylindrical grumous co- 
hering mass, presenting indications of cellular sub-division. 
. Pl. 39.—Fig. 3. a stigmatic line, b inflexion; e very young 
pistil. 
The placentz in this last are obviously continuations of the 
inflexed margin. Stigmatic line is traced out, it is linear 
stigmatic, concave, extending as far as the style, or petals, 
the spaces between which are tolerably wide. No trace of 
an ovary at this period. 
Just as the corolla pushes out from the calyx, the cells are 
filled with a grumous opaquish mass; the walls of the cells 
themselves are similarly coloured and opaque, and irregu- 
lar, as if torn. 
The young flower at one time looks exactly like a button 
with raised lobed edges, the lobes which are to become the 
future stamina are only just internal to the others. 
The separation of the young grains takes place just when 
the corolla is about emerging from the calyx ; the grains are 
quite transparent. The divisions are 2, 9, 4, generally 3, but 
2 are not uncommon. -
