LEPTOPUS

The genus Leptopus was established by Decaisne (1844), based on Leptopus cordifolius Decne. Morphologically the genus closely resembles Andrachne L., with which it has been united by various authors ( Müller 1866, Pax & Hoffmann 1922, Govaerts et al. 2000). In the most recent classifications ( Webster 1994, 2014, Radcliffe-Smith 2001) it is kept separate. Phylogenetically (e.g., Vorontsova et al. 2007), it is distinct from Andrachne , but morphologically the main difference is only in the position of the ovules: anatropous in Leptopus , hemitropous in Andrachne (Vorontsova & Hoffman 2009) . Pojarkova (1940, 1960) made the first revisions of Leptopus , the latest is by Vorontsova & Hoffmann (2009), who also present a more elaborate history of the genus.
