 Marsilea Sporocarp:
Marsilea is heterosporous, i.e. it produces two types of spores-microspores and
megaspores.
These spores are produced in microsporangia and megasporangia.
These sporangia are brought in a special type of spore-producing organ called
sporocarp.
The sporocarp are borne laterally on the peduncle of leaf either near the base or a little
higher up.
Each sporocarp is a flat structure, in the form of oval or bean-shaped biconvex
structures.
It is green and soft when young, but when mature, it becomes very hard and brown.
It consists of a short stalk-like structure known as peduncles and body.
The point of attachment of the peduncle to the body is called raphe.
