Usage examples of "clavatum".

So I was going to suggest that for the sake of the headaches of all future generations of students, as well as for the convenience of the human race which can memorize club moss more readily than Lycopodium Clavatum, we base the nomenclature of our new sciences, and reestablish the terminology of the old, upon English.

Probably the spores used commercially are derived also from other species in addition to Lycopodium clavatum.
