Meanings of equisetales in inglês

The Equisetales likewise have a long history, and manifestly attained their greatest development in Palaeozoic times.

At the same time the oldest Equisetales show a somewhat megaphyllous character, which was more marked in the Devonian Pseudoborniales.

The available data, though still very fragmentary, certainly suggest that both Equisetales and Sphenophyllales may have sprung from a common stock having certain fern-like characters.
