Three legume fossils collected from the Miocene Duho Formation of Yeonil Group in the northern Pohang Beach, Gyeongsangbug-do, Korea were described as Albizia miokalkora Hu and Chaney. This species has only appearing in the Miocene floras of Korea, China and Japan until present. It has wide distribution from warm temperate to subtropical-tropical regions but, the diversity of the species of Albizia is not so high. It is considered that the fossil Albizia miokalkora Hu and Chaney might have adapted to the warm climate such as warm temperate climate and subtropical to tropical climate.

Fossil legumes of Albizia miokalkora Hu et Chaney (Mimosoideae) were found in the Miocene Duho Formation of the Yeonil Group distributed along the coast of Yeonil Bay in the Pohang area. The legume is flat and long and has 5-7 rounded seeds. The legumes of Albizia miokalkora are rare in the Cenozoic floras of the world and only known to Middle Miocene of East Asia. The fossil Albizia may use one of the important taxa to construct the biogeographic history of East Asia. This discovery is the first record of Albizia from the Neogene strata of Korea.

Two fruit fossils of Albizia miokalkora were collected from the Miocene Duho Formation of Yeonil Group in the northern Pohang Beach and Changpodong, Gyeongsangbug-do, Korea. The legume is flat and long and has 7 rounded seeds. Although the legume fossils are preserved as impression, they show their whole shape well. It is considered that the fossil Albizia might have flourished in a warm temperate climate in East Asia. This discovery is the second record of Albizia from the Neogene of Korea.
