56 DEVELOPMENT OF THE FLOWER 
grain from being granular becomes quite transparent before 
the production of the amylaceous granules. 
Is there any relation between the structure of the leaves 
and of the anthers of unilocular anthered plants ? 
Obs. (PI. 23.—D.) 1. [The glands are evidently secretions 
from the furrows, towards the angles of which they first ap- 
pear, hence the want of a groove, the lateral lines marking out 
the future fissures now exist ; it is along the margin that the 
crura are developed. 
No division of the placenta now. 
Contents of cell quite grumous, no subdivision. 
Membrane just traceable. 
But since it is evident that the mass is capable of deve- 
loping cells, it is more consonant with probability to suppose 
that the membranous sac is developed from it also. 
It is singular that when the ovule was flat, it had on one 
side two venules, while the other with incurved margins had 
only one central vein.]* 
Obs. Sac easily separable, filled with grumous matter, 
scarcely any traces of cells in its external aspect. Yet it con- 
sists as in the perfect state of a sac containing simple cells 
with a granular nucleus. (Pl. 23.—D.) 5. [Appearance of 
cells, in the sac but only partial, when glands unite no crura, 
the grumous mass may be said to be just separating into 
massules. |* 
CarorRoris Procera.—PI. xx. (A.) 
1. Very early bud, calyx only developed ; its centre is 
-occupied by a mucilagino-cellular protuberating 
disc. 
2. More advanced, traces of 5 lobes (petals) in the disc. 
3. Considerably advanced, 1. 2. of pl. B. to intervene. 
Calyx laid open, corolla of 5 scales much like the 
anther at a more advanced period or of the next 
stage rather.
