THE GENUS CTENOMERIA 171 



by Pax in 1898 (Bull. Herb. Boiss. vi. 735) as Tragia Schlechteri, 

 from Natal specimens collected by Schlechter. This differs from 

 the other species in being still more pubescent, and in having 

 deeply 5-lobed leaves with the lobes usually obtuse. As regards 

 its flowers, this plant is not distinguishable from C. capensis, and 

 further field study may supply links connecting the two.
