The status of Jambadostrobus Chandra and Surange (Glossopteridales)

Abstract: Jambadostrobus was established to accommodate fossils consisting of several multiovulate elliptical–ovate fructifications attached to the midline of glossopterid leaves. Two species have been assigned to the genus: J. pretiosus (the type species) and J. hillii from the Late Permian of India and Early Permian of Australia, respectively. Re-investigation of the original specimens reveals that only solitary fructifications are attached to the subtending leaf in J. pretiosus, hence the species is transferred to Plumsteadia, which was founded on equivalent characters. The putative reproductive organs constituting the single Australian specimen of J. hillii are re-interpreted to constitute a broad area of preservational damage on the leaf, hence Jambadostrobus is considered to be a nomen illegitimum.
