WIELAND” has secured transverse seed-sections of one of the Bennettitales 
showing tissue filling the archegonium, which he interprets as the proembryo. 
If he is correct, this is an interesting confirmation of the current morphological 
view that the Ginkgo type of proembryo is the most primitive among living gymno- 
sperms. The Previously known mature seeds of Bennettitales are singular among 
8yMnosperms in the entire absence of endosperm; and now even in this reported 
Proembryonic stage WIELAND finds no trace of endosperm.—J. M. C
