lycopod

But only in ferns and one other plant group called lycopods are the two plants capable of living independently.

Sphenophyllum was a slender climbing plant with whorls of leaves, which was probably related both to the calamites and the lycopods.

To one of the lycopods, called Selaginella, reference will hereafter be made in connexion with its very instructive reproductive process.

We have examples of the last-named class in the ferns, lycopods and horsetail plants.

Upon the walls themselves I could clearly make out the outline, as plain as a sun picture, of the fucus and the lycopods.
