The present contribution caiTiea these Materials to the end of the 
Galyciflorss. The ordera inclnded in it are Datiscacem, Drqseracemi 
Passifioraceie^ Begoniacess^ FicoidesB, UmbeUifersBf and Cornacew, It has 
not been possible for me to prepaid my account of the Calyci floral oi-ders 
in the exact sequence followed in Hooker's Flora of British India ; each 
oi-der, however, bears the ordinal number gi^en to it in that work. The 
species described in the present paper are 47 in number^ and of these 
fourteen belonging to the genns Begonia, and two belot^ging to Mttstisriaf 
are now to Bcience. I hope in fiitnr© contributions to take np the 
orders belonging to the groups Ooroliiflorm and Incompletm* 
Order LSVII. DATISCACE^.
