On a living species of Junlandicarya found in South Yunnan

Abstract

The characteristics of the fruit of Rhamphocarya integrifoliolata, both in its endocarp and its seed, are similar to those of the fruit for the fossil genus Juglandicarya, described by Reid and Chandler from the Eocene London Clay Flora of south-eastern England, although its fruit is much larger than that of the fossil genus. Since the London Clay Flora was mainly of a tropical rain forest closely allied in floristic composition to the Indo-Malayan flora, just as in the case of the flora of south-eastern Yunnan where Rhamphocarya integrifoliolata flourishes, the identification of the living genus with the fossil one is even more indubitable.
