Oxalis jiayinensis, a new species of the Late Cretaceous from Heilongjiang, NE China

Abstract

Abstract: Oxalis jiayinensis, sp. nov., is described from the Late Cretaceous (TuronianSenonian) in Jiayin County, Heilongjiang Province, northeastern China. The seed is about 1 mm long, less than 1 mm in diameter, crescentic with obtuse apices and 9～10 transverse ribs. The seed wall is composed of equiaxial, strongly thickened sclereids. The fossil repre-sents the oldest occurrence of the family Oxalidaceae in the world.

Key words: Oxalis, Seed, Late Cretaceous, Heilongjiang
