Cordaites

A plant group, which is now extinct, that includes the Coniferales (pines and firs) and the Cycadales (cycads). The Cordaites were tall, slender trees that often attained heights of 100 ft (30.5 m). For a considerable height above the ground, the trunk was devoid of branches. The long, straplike leaves now form matted masses among the Coal Measure fossil plants.
