The 'sores' on the leaves of A. maculatum in the book are true to 
life, they really are both sunken and raised like black blisters. 
This occurrence (bullate leaves) is also found in Biarum pyrami and 
B. bovei where black-spotted leaves occur, also in Eminium 
koenenianum where the 'sores' are white. Odder still, in some forms 
of B. pyrami the 'sores' are plain green like the remainder of the 
leaf.
