Miroviaceae

Preserved leaf sections of Mirovia gothanii, from Gomez (2002).

Belongs within: Coniferophyta.

The Miroviaceae is an extinct group of conifers known from the mid-Jurassic to the Late Cretaceous, with linear leaves similar in appearance to the modern umbrella pine Sciadopitys verticillata. They differ from modern conifers in having the closely placed stomata restricted to a sunken groove with a protruding margin on the abaxial side of the leaf (Gomez 2002).
