... sperms to the higher seed-plants, it may be of some importance to consider the

The occurrence of typical pteridospermous fructifications with Pecopterid foliage

Thus, there is a certain amount of justification for assuming that the sex organs

Although the filicinean series gave rise to seed plants at an early date, evolution
