The drawings from which the figure in the Botanical Magazine were taken, repre- 
sent the stigma as bilobed like that of 7. geraniifolia. This bilobing, not accurately 
reproduced in the Botanical Magazine, is still more inaccurately represented in the 
figure in the Flore des Serres, ‘This species and the following form a transition to the 
section Thunbergiopsis.
