[521] Bertrand, P. (11) p. 47.

[522] Since this account was printed my attention has been drawn by Dr Scott to a note by Bertrand in which he considerably modifies his views. He finds that Hierogramma and Syncardia are probably different states of the petiole of Cladoxylon and while agreeing with Solms-Laubach’s conclusions he has been able to add important new facts. Bertrand has now given up the opinion that Clepsydropsis is the petiole of Cladoxylon. For further details students should consult the preliminary note which it is hoped will be followed by a fully illustrated memoir [Bertrand, P. (14)].
