Abstract

A new species of Siderasis from the state of Espírito Santo is here described. This new species is readily differentiated from S. fuscata by its sessile to subpetiolate leaves covered by hyaline to light-brown indumenta, blades with a well-defined white stripe along the midvein on the adaxial side of the blade, main axis of the main florescence elongate, thyrsi reduced to one elongate cincinnus, bracteoles present, anthers purple to bluish–purple, filaments and style apically purple to bluish–purple, aril cream-colored and slightly hyaline, and by the production of unique axillary flagelliform-shoots after the flowering period. I present a description of this new species, along with illustrations, a distribution map, comments on conservation assessment, ecology and taxonomy, and a table comparing the new species with the only other accepted species in Siderasis. Furthermore, I designate a lectotype and an epitype for S. fuscata.
