  • Descrição: Geometric morphometry has evolved as a powerful tool to unravel species delimitations within the genus Aristolochia . A survey conducted on the variation of Aristolochia trilabiata flowers and leaves revealed an overlooked entity in its affinity, which is newly described herein as Aristolochia franzii . The new species differs from its relative A. trilabiata by various floral characters, notably the presence of papillae on both the upper and lower limb zones, the presence of a well defined medial upper limb zone, the number of veins on the lateral upper limb zone, a considerably shorter tube, and the relative position of upper and lower limb zones. Furthermore, the leaf shape of A. franzii is cordiform-elongate to hastate, compared to the consistently more compact and shorter cordiform leaves of A. trilabiata. So far, A. franzii has been recorded from Northern Brazil (Amazonas) and French Guiana. An illustration of the diagnostic characters and comparison with A. trilabiata is provided, as well as the geographic distribution and a preliminary assessment of the conservation status.
