“…It was Erdtman (1956) who for the first time pointed out the affinities of some fossil pollen grains from the Warkalli lignite, with the modern Ctenolophon. These were originally reported by Rao and Vimal (1952) and Vimal (1953) as Hexacolpites and Septacolpites pollen types. There has been so far, however, no detailed systematic study of the fossil pollen of Ctenolophon type from India.…”

The paper deals with a systematic study of the pollen grains of Ctenolophonidites Van Hoeken Klinkenberg recovered in fair abundance from a lignite sample near Warkalli (Varkalai) in Kerala State. The geological age of the Warkalli lignite is Miocene, possibly Upper Miocene. The following species have been described in the paper, viz. Ctenolophonidites costatus, C. keralensis sp. nov., C. erdtmanii sp. novo and C. saadii sp. novo The fossil pollen grains show remarkable similarities with the pollen of the modern genus Ctenolophon of Ctenolophonaceae and are undoubtedly related to the latter. The paper comments upon the geological history of Ctenolophon both in time and space. The known geological history of this genus indicates that it enjoyed a much wider phytogeography during the Tertiary period compared to its present rather highly circumscribed distribution.
