The appearance of Hooker's Flora of British India and my subsequent own investigationi have since broufht 

 about some changes not only in the nomenclature but also in the analytical keys of the species. However i^ is 

 not possible to introduce these here fully, but altered names or minor corrections in the keys are made in the 

 sequel as far as possible ; the former will be found in foot-notes.
