Some well-preserved conifer leafy shoots and female cones from the Lower Cretaceous changcai For- mation near Fudong of Helong, eastern Jilin, Northeast China are studied. Based on gross morphological and cuticular study, a new species, Elatides helongensis Sun et Zhao （ sp. nov. ） is described systematically. The new species is characterized by persistent, linear or slightly falcate leaves with obtusely acute apex, attached helically on the shoots. Female cones of the new species are terminal and oval, composed of persistent helically- arranged rhomboidal scales and erect seeds. One erect seed is growing on each scale. Leaf cuticles are hyposto- matic. Monocylic stomata are ellipse, composed of 2 sunken guard ceils and 4-8 subsidiary cells. Moreover, the cuticles of a young female cone of Pityostrobus yingchengensis Yang are described for the first time.
