The subfamily Athrotaxoideae is an early divergent lineage of Cupressaceae that contains the extant genus Athrotaxis and three extant species (A. selaginoides, A. laxifolia, and A. cupressoides) restricted to Tasmania.
Recognizing key cuticular features in extant species is fundamental to better understand, identify, and interpret the richness and diversity of the Athrotaxoideae fossil record. Our objectives are to describe in detail the epidermal morphology of all extant species of Athrotaxis and detect, if possible, cuticular characters that can be used to differentiate extant and fossil species in the group.
