INTRODUCTION. 
The genus Cedrela was first founded by Linnaeus on Cedrela odorata, 
a West-Indian species in which the receptacle of the flower is very 
much elongated and which has seeds winged at their lower end only. 
An Indian and a Javanese species having a much shorter receptacle 
and seeds] winged at both ends were afterwards added to the genus by 
Roxburgh and Blume. Then A. de Jussieu and Royle again added to 
it two Asiatic species having also a Relatively short receptacle but the 
seeds of which have afterwards been found to be winged only at their 
upper end. Later on Roemer 1 detached all the species with a short 
receptacle from the Cedrelas and formed with them his genus Toona. 
The subsequent writers, however, continued to include them in genus 
Cedrela, an arrangement which I adopted in my monograph of the 
Meliaceae, published in 1878. On the contrary, Harms 2 has recently 
reverted to Roemer’s classification. 
Such was the state of things when I undertook the present revision 
with the help of the materials of the Calcutta herbarium which had 
been put at my disposal for that work. It was of course impossible for 
me to carry it out without examining anew the characters distinguishing 
the West-Indian and American from the Indian species, since on my 
opinion of the importance of these characters depended the generic 
v name to be adopted for the latter. Thus I was led to extend my revi- 
sion to the whole genus, and I must say that this study has confirmed me 
in the idea that there is such a close affinity between the species of the 
two groups, that it is quite natural to keep them together in the same
