Bracteophyton is a genus of extinct vascular plants of the Early Devonian (around 420 to 390 million years ago). Fossils were first found in the Xujiachong Formation of eastern Yunnan, China. The smooth stems (axes) mainly branched dichotomously. They bore terminal 'spikes' (strobili) consisting of spirally arranged fertile 'units'. Each unit was made up of one or two bracts and a spore-forming organ (sporangium) between a bract and the stem.
