Article: Structure of the spore wall in certain miospores belonging to the series Cingulati Pot. and Klaus 1954
A. H. V. Smith
Miospores of the genera Densosporites and Anulatisporites are described in which the spore wall consists of two separate membranes. The inner membrane, considered to be the intexine, forms a 'central body' which can be seen in equatorial section of the spore exines in polished surfaces of coal and in specimens isolated from the coal.
