Armoricaphyton is an extinct monospecific genus of vascular land plants described from Early Devonian (late Pragian-earliest Emsian) outcrops of the Chalonnes Formation in western France.

[1] The plant consists of small, leafless, longitudinally-ribbed axes that branch pseudomonopodially.

Pairs of fusiform-shaped, twisted sporangia preserved as adpressions were found in association with the axes and may belong to this species.

[1] Permineralized specimens reveal the oldest documented wood or secondary xylem of any known fossil plant.

[1] Franhueberia gerriennei is also one of the earliest land plants described from the Early Devonian (late Emsian) that was known to have wood.
