		In apospory the converse phenomenon~ is seen, the gametophyte springing vegetatively from the sporangium, receptacle of the sorus, or leaf-margin of the fern-plant.
		The sporangia arise simultaneously in the sorus, which is borne on the under surface of the ordinary pinna in those species with large sporangia the latter form a single circle in others sporangia may also arise from the central part of the receptacle.
		On the ground mainly of an examination of the sorus and sporangium, Bower, has shown that the Filicaceae may be divided into three groupsthe Simplices, Gradatae and Mixtae in which the sporangia arise simultaneously, in basipetal succession, or irregularly in the sorus respectively.

		When the sporangia within a sorus are mature the indusium shrivels to expose them, the wall of each sporangium capsule opens, and the spores are released to the surroundings.
		Observe a sorus on this pinna with a dissecting microscope and draw it, labeling the sporangia and the indusium.
		Using a compound microscope, examine a prepared slide of a fern leaflet bearing a sorus.
