1928

A comparison of the present with the past geographical distribution of the group in India has thrown some light on the origin of the modern coniferous flora of the Himlayas. [...] As it may be of interest to read in the original the views of a scientific writer of the eighteenth century on the significance of the phenomenon an extract from his account is quoted in the footnote 7. Since then the fossil trees of Tiruvakkarai have been the subject of comment on several occasions both in scientific journals and in newspapers 8 but I am not aware of any published description o [...] The species is here assigned to the latter genus in view of the fact that the pores of the medullary ray pits in the few places. [...] The shape and distribution of the pits in the field is clearly exhibited in the medullary ray on the left while that on the right shows the narrow and slilike almost vertical pores the borders having been mostly removed in the grinding (a few of the borders are present but are out of focus). [...] The wood is referred to Mesembrioxylon partly in view of the narrow and slit-like character of the pore which in Cupressinoxlon is usually wider and more or less elliptical and partly in view of the stoncells in the pith.
