The present work deals with the changes during the development of the Pseudocarp in
The number of bundles increases from the base towards the distal end in a peculiar way, which has been described in detail. Some of the bundles appear to arise
The development of resin ducts in the pseudocarp is described in detail. They develop lysigenously.
The growth of the pseudocarp is also dealt with. There are three factors which helps in the enlargement of the pseudocarp (1) segmentation and enlargement of the vascular bundles, (2) the enlargement of the parenchymatous cells in the cortex and pith and (3) the increase in number of the resin ducts and their enlargement.
The amount of tannin contents in the cortical and medullary cells was also studied. The tannin contents increase gradually up to the time when the pseudocarp is 22–25 mm. in diameter. Thereafter, they reduce gradually and disappear, completely.

The floral morphology of 9 species of Scrophulariaceae belonging to 5 genera included in 3 tribes is studied.
The floral anatomy suggests that the condition with four stamens is resulted from a five-stamened condition by a gradual reduction of posterior stamen.
The placentation in
