What Is Gymnocladus?
Kodak, an extinct class of gymnosperm conifers. Most of the trees are tall and thin, with stems as high as 20 to 40 meters, but the diameter is not more than 1 meter. The upper part has many branches, forming an oval or spherical crown.

- An extinct genus of gymnosperm plants. Most of the trees are tall and thin, with stems as high as 20 to 40 meters, but the diameter is not more than 1 meter. The upper part has many branches, forming an oval or spherical crown. The leaves are band-shaped or spoon-shaped, up to 1 meter in length, spirally arranged. The veins are bifurcate, dense, nearly parallel. The reproductive organs consist of short reproductive branches in two rows. Short branches are born between the axils of the sterile bracts, and are unisexual or heterosexual. The top of the microspore leaf is slender with small spores, and the macrospore leaf is ovules. The secondary xylem of the roots and stems is well developed. The medullary part in the center of the stem is large, and the medullary tissue is split horizontally into thin slices. The Kedamu fossils may have appeared in the Late Devonian, and the Early Carboniferous began to have reliable fossil records. The Late Carboniferous to the Early Permian were the most prosperous, forming a broad and dense forest, and it is one of the main coal-forming plants in the Paleozoic. The Late Permian began to decline, and it was completely extinct at the end of the Triassic. The class originated from the ancient fern order of the gymnosperms. [1]
