Earliest evolution of stipules among vascular plants documented in the late Paleozoic stem group of Marattiales
Original language description
Based on extraordinary collections from the early Permian Wuda Tuff Flora, we report, for the first time, aphlebia fossils organically attached to psaroniaceous petioles. The psaroniaceous aphlebiae are homologous to marattiaceous stipules, as evidenced by numerous shared characteristics. Functionally, psaroniaceous stipules appear to shelter juvenile fronds and the stem apex, with a continued role in mature fronds. Furthermore, their continued and potentially indeterminate growth, along with their fully laminated structure, suggests a possible role in vegetative propagation after detachment from the parent frond. However, no direct fossil evidence of stipules acting as vegetative propagules is currently available.Our discovery provides unprecedented view of stipules in psaroniaceous tree ferns. The discovery of psaroniaceous stipules is significant, as it represents the earliest known stipule in the plant kingdom and underscores their multifunctional roles in plant development.
