Referee's report by James William Helenus Trail, on a paper 'Longitudinal symmetry in Phanerogamia' by Percy Groom Sectional Committee: Botany Not recommended for publication in the 'Philosophical Transactions of the Royal Society'. Suggests the author should be asked to prepare a brief report outlining the obect and methods of investigation. The investigations are important and should be continued, but the present paper is too long, repetitive, specifically detailed and in places incomplete to be of great use at this stage. Official addendum indicates that the paper as it stands would cost £160 for print and £34 for illustrations. As publications are an increasing cost for the Royal Society, it would be best to consider if the paper could be reduced. [Published in the Philosophical Transactions of the Royal Society] Endorsed on verso as received 15 February 1907. [February 1907]
