The paper deals with a well preserved pteridophytic strobilus from old but unexplored locality, Singhpur (Sanuncer), M.P., India. The specimen is an eligulate heterosporous strobilus. Megasporophyll bearing part of the axis is 10 x 4.5 mm showing megasporophyll and megasporangium. Megasporangium measures 1.5 x 1.8 mm, unilayered wall with 2 to 4 megaspores. Megaspores oval, 320 x 480 ?m in diameter, two layered with big air spaces as floating devices. Microsporangia are scattered, 420 x 480 ?m in size, unilayered wall with 12 to 16 microspores. Microspores are 50 x 80 ?m in diameter, oval, two layered and tri-radiate. Lasurae present up to the periphery. Parenchymatous axis with intercellular spaces. The fossil specimen, after comparing with different pteridophytic strombilli, is seen that it closely approaches the division Lycopodiophyta but not with any genera, hence named as Lycopodiophytostrobus intertrappea gen.
