This species of Gladiolus is here figured for the first time. 

 Eehmann collected it between the Elands Eiver and Klippan, 

 and it was then lost sight of until rediscovered by Dr. I. B. 

 Pole Evans at Nylstroom, Waterberg District, in February, 

 1917, and has now been established in the Gardens of the 

 Division of Botany, Pretoria. We are indebted to Mrs. Frank 

 Bolus for identification.
