Three species of Pseudolarix including P. japonica, P. sp. A, and P. sp. B, all belonging to Pinaceae, are systematically described from the Middle Miocene Duho Formation of the Yeonil Group based on the detached seminiferous scales. The presence of Pseudolarix in the Yeonil flora indicates that various kinds of Pinaceae did flourish during the Middle Miocene. The occurrence of Pseudolarix is the first record in the Korean Tertiary flora.
