Periglossum podoptyches (Apocynaceae-Asclepiadoideae), a new species from KwaZulu-Natal province, South Africa

Abstract

Periglossum podoptyches is described as a new species from the KwaZulu-Natal Province of South Africa. As a rare species its conservation status is assessed as Vulnerable. This new species is closely related to both Periglossum mackenii and P. kassnerianum from which it differs mainly in having folded flaps of tissue at the base of the face of the restricted basal stalk of the staminal corona lobes. A comparative table with diagnostic morphological features and a key to the species of Periglossum are provided
