Sidney R. Ash Three plants based on megafossils are described from the Late Triassic Chinle Formation at a new locality in north-eastern Arizona. They are the leafy shoot and cone of Selaginella anasazia sp. nov., the leafy and fertile branches of Dechellyia gormani gen. et sp. nov., a conifer of uncertain affinities, and Masculostrobus clathratus sp. nov., a male coniferous cone. The cone is noteworthy because it contains pollen closely resembling the Late Triassic grains called Equisetosporites chinleana by Daugherty (1941) and later referred to the genus Ephedra by Scott (1960).
