XXXL— .0/1 the Canellacese. By John Miers, F.R.S., F.L.S.&c. 



Having been engaged for a long time in the study of the Clu- 

 siacece, 1 have been led to examine the several genera that have 

 been referred at different periods to that family, and in this 

 manner Canella and Cinnamodendron came undei* my especial 

 notice. The former genus was arranged by DeCandolle and 

 Choisy in GuttifercB, but it was partially separated from the 

 order by Martins and Endlicher, and made the type of a sub- 

 order of that family under the name of the CanellacecBj asso- 

 ciating with it Cinnamodendron and Platonia. It will, however, 

 be seen that Canella has no relation with Platonia^ but that its 

 real affinity tends towards the Winteracece. I will therefore 

 proceed to state my reasons for this conclusion, will expose the 

 characters of both groups, and describe their genera severally. 



This small family consists only of the two genera above men- 

 tioned, Canella and Cinnamodendron. They form evergreen 

 trees, with a bark possessing the taste and smell of cinnamon ; 

 they have a copious foliage of alternate, somewhat fleshy, exsti- 

 pulate leaves, which are furnished with dotted glands, and have a 

 taste similar to that of the bark : the flowers are small, in short 

 axillary or terminal corymbs, having a persistent calyx of 3 sepals, 

 5 petals with dotted glands, or sometimes 10 petals in 2 series, 

 extrorse monadelphous stamens, a unilocular ovarium with two 

 or more parietal placentations ; a small, baccate, 1 -celled fruit, 

 containing a few black, shining, reniform seeds having a parietal 

 attachment. Many of these characters are possessed by the 

 Winteraceoiy from which the Canellacece differ in the union of 

 their stamens into a monadelphous tube ; in the shape and dis- 

 position of the anther-cells ; and in lieu of several distinct car- 

 pels, they have only one solitary unilocular ovary, with 2 to 5 

 parietal placentations. In the former family, whether there be 

 sevei-al ovaria, or whether by abortion they be reduced to one, 

 these, although 1 -celled, invariably exhibit a single placentation 

 along the ventral face.
