Sigillaria

Fossil of Sigillaria trigona, on display at National Museum (Prague)

Sigillaria is a genus of extinct, spore-bearing, arborescent (tree-like) plants. It was a lycopodiophyte, and is related to the lycopsids, or club-mosses, but even more closely to quillworts, as was its associate Lepidodendron.
