X HE following new or litlle known genera are all from India, 

 and required early attention while engaged in arranging our 

 materials for the Prodromus Florae Peninsulae Indite Orientalis, 

 which we are now preparing for publication. The plan and 

 limits of that work not affording us room to describe them with 

 a fulness of detail, necessary to make them properly understood, 

 and altogether preventing us from entering into any discussion 

 on their affinities, we propose doing so through the medium of 

 this Journal. 



With this view we shall, from time to time, transmit detailed 

 characters of such genera as may require elucidation. — Arlary^
