The foregoing is a preliminary report chiefly on flowering 

 plants. A complete catalogue, so far as it can be made with 

 the information at hand, which will include the cryptogams, is 

 in course of preparation. 



After the tirst part of this Hst had gone to press collections

Notes on some of these are added in the latter part of the 

 list, but the greater number will be reported upon in the sub- 

 sequent catalogue.
