diplospory (gonial apospory), the gametophyte arises from an unreduced
megaspore; whereas in apospory (somatic apospory) it arises from an ordinary
somatic cell of the sporophyte, which is, of course, also unreduced. Obviously the

There are not many reports of apospory in liverworts. Aposporous outgrowths
were observed in Anthoccros (Borenhagen. 1926: Lang, 1901; Rink, 1935), but
