Abstract

Under the name Sporojuglandoidites jurassicus a new sporomorph is described from the Jurassic rocks of India. The sporomorph is distinguished by the presence of foraminoid apertures on its body-a character not met with in any plant group except the angiosperms. In general characters it seems to resemble the juglandoid grains.
