Calamopityaceae ✝
| Description | Calamopityaceae is the largest family of the division of extinct seed-bearing plants (spermatophytes) known as Pteridospermatophyta. This family is characterized by its petioles and specific wood pattern, and it grew only in the Paleozoic era, specifically in North America and Europe. It is divided into three genera based on stem structure: Calamopitys, Stenomyelon, and Diichinia. It was named by Solms-Laubach in 1896. Since then, its genera have been added to and grouped differently, though these three genera are currently depicted as the only genera of this family.
