Abstract
G. R. WIELAND has a very interesting discussion o of the origin of Angiosperms in the Proceedings of the International Congress of Plant Sciences held at Ithaca, vol. 1, pp. 429–456 (George Banta Publishing Company, Menasha, Wisconsin, 1929). Naturally this account contains a particularly interesting recapitulation of the main features of the discoveries in the Cycadeoideae with which the author's name is now linked through the genus Wielandiella, established as the result of Nathorst's fine reconstruction of difficult Swedish and Yorkshire material; but this general account is particularly valuable as it synthesises the available material, in a problem which ranges the whole globe and a considerable part of geological time.
