Mapes G and Schabilion JT. 1979. Millaya gen. n., an Upper Paleozoic Genus of Marattialean Synangia. American Journal of Botany. 66(10):1164-1172
Anatomically preserved fertile marattialean pinnules from the Lower Permian (Wolfcampian) Bursum Formation in Tularosa, New Mexico, and isolated synangia from the Upper Pennsylvanian (Missourian) Stanton Formation near Tyro, Kansas, are described The sessile synangia are partially sunken into the pinnule lamina and arranged abaxially in a single row on each side of the midrib. Comparisons are made with other fossil and modern marattialeans and the evolutionary significance considered.
