One of the charming spring plants found on the High 

 Veld of the Transvaal and especially abundant after early 

 winter veld fires. The corolla is of the same deep blue seen 

 in many species of Lobelia, and the colour of the flowers makes 

 the plant a conspicuous object in the veld. Our illustration was 

 made from specimens collected by Dr. I. B. Pole Evans at 

 Kaalfontein, between Pretoria and Germiston.
