CALOTROPIS PROCERA. 55 
The angles of stigma are not furrowed, although there is 
a leading thereto; the stigmatic tissue is well developed, but 
the linear Pepe of the cells is scarcely discernible, 
with a j: 
(PI. A No 7. The cells have their future figure, and 
the margins are commencing to be distinct towards the apex. 
Contents, a grumous, highly minute granular mass. 
Placente have assumed their form: more incurved than 
margins ; cells indistinct, mucilagino-grumous tissue. 
Pk ) Fig.—Series.—At this period the cavity of 
the cell is only traced out by yellow colour ; if examined at- . 
tentively it will be found to have the sides of the yellow part 
passing into one and the same with the body of the anther: 
it is also nearly solid; £he centre contains a small quantity 
of grumous granular matter. See (Pl. 24.— 
Still earlier there is no yellow colour, the margins of the 
mass to be separated have chiefly towards the future apex 
become irregular, and distant from the mass. Pressure 
shews elsewhere that it is continuous with the body of the 
anther ; the centre contains a small grumous mass. 
So two changes go on: one, separation of the mass ; the 
other, its dissolution into granular matter. 
The mature gland is dark-brown ; angular convex in front 
with a deep furrow. 
Convex behind, no furrow, and rather more rough. 
The crura are of the same colour, but less deep ; the wing 
yellowish, passes down to the knee of the crus ; the cellular 
membrane at the lower angle uncoloured. 
The stages or changes as follows : 
Separation of grume. 
Appearance of sac. 
Aggregations of grume. 
arance of cells in intines. 
Development of amylaceous granules. 
From the action of iodine being confined to the contents 
of the grain itself, it appears as though the granular matter 
of the nucelles was exhausted during the formation of the 
outer coat. This agrees with direct observation, the young
