Aphyllopteris is a poorly known genus of extinct Devonian land plants formerly placed in the Rhyniophytina.[2] It is considered an artificial group for sterile naked axes that branch pseudomonopodially.[3] Early Devonian records of this genus are found in Belgium, France, Norway, Poland, and Russia, and possibly Uzbekistan.[4] Putative Middle to Late Devonian records of this genus include A. delawarensis reported from Frasnian outcrops in New York[5] and Aphyllopteris sp. reported from the Givetian outcrops of the Beckers Butte Member of the Martin Formation in Arizona.[6]
