Nemesia barbata (Thunb.)Benth.

Syn. Nemesia guthrei Hiern. incl. N. grandiflora Diels.

 

An abundance of these pretty flowers were observed and photographed on a recently burnt fynbos field on Cape Peninsula, Western Cape province, South Africa, 29 August 2015.

Visible light: Nikon Df, Voigtländer 125 mm f/2.5 APO-Lanthar lens, daylight

 

Due to its almost 3-D appearance, shooting this flower in UV under field conditions was a little tricky. I selected this capture as it best showed the pronounced band of conical cells on the front corolla lobe.
