aie tamily with which the Anonacee are most “nearly ‘allied is the Magnoliacee ; 
the ternary symmetry, multiple fruits, alternate, simple, entire leaves, and the woody 
habit being the chief points of agreement. On the other. hand, the limitation of 
the pieces of the perianth to nine in Anonacew ; the dehiscence of the fruit and the 
frequent presence of stipules and of an arillus in Magnoliaceee afford points of difference. 
In the seeds of both orders albumen is present, which in Anonacee ‘ig invariably, and in
