Referee's report by Dukinfield Henry Scott, on a paper 'The microsporangia of the pteridospermeae, with remarks on their relationship to existing groups' by Robert Kidston Sectional Committee: Botany Recommended for publication in Philosophical Transactions. All the photographs are extraordinarily good but even in the best photographs of fossil impressions it is often difficult to see details. The best methods of reproduction will be essential so that there may be no loss. He queries the evidence for the bilocular structure of the sporangia, which he thinks is quite insufficient to prove this structure or even render it probable. The examination under Kidston's guidance, of several of the original specimens failed to convince him. Explains why he thinks Miss Benson's fossil to be a Crossotheca, not necessarily identical with either of Kidstons' species. After examination of the specimens, he explains why he thinks the author is mistaken in regarding his Diplotheca stellata as a group of microsporangia. The author's attention might be called to the divergence of opinions that exists. [Published in Philosophical Transactions B, 1906]. Endorsed on verso as received 8 February 1906. 7 February 1906
