over-ripe apples, and, to my taste, not particularly 
pleasant; but the wood and bark have a fine 
aromatic fragrance. 
The structure of the flowers is accurately de- 
scribed by Lindley, in the generic character, 
copied by Loudon, p. 935. In many important 
and remarkable points it agrees with that of the 
genus Rosa: in the nature of the calyx-tube, the 
position of the ovaries within it, with their styles 
emerging from its mouth, and the insertion of the 
stamens; but it differs widely from Icsacex 
in the structure of the anthers, the number and 
arrangement of the parts of the perianth, and the 
absence of any distinction between the sepals and 
petals. There is no doubt however that the Caly- 
canthacez are closely allied to the Rosacez. The 
affinity to Rosacez is disputed by Bentham and 
J. D. Hooker, who (Genera Plantarum, vol t. p. 16), 
contend that the appearances which have led 
to this conclusion are deceptive. They hold that 
the tube which incloses the carpels is not a part of 
the calyx, but is a hollow torus or receptacle, 
analagous to that of Nymphcea. They place the 
order Calycanthaceze next to Magnoliacez, ob- 
serving that it is allied in particular to Illicium, 
though in some respects very anomalous.
