INDEX. 
Names, as ‘ Acrasieae,’ ‘ Abrothallus,’ ‘Achlya Braunii,’ with no further addition, refer to the 
course of development of the Orders, Genera, &c., as described in the second division of the first 
part and in the second and third parts; those which are followed by some additional word, as 
‘Achlya apiculata, capacity of germination,’ refer to the remaining sections of the book. An 
asterisk after the number of a page indicates a Figure.
