Postscript. 



The Orders which still remain to be treated in the third 

 volume, are the two heterogeneous assemblages of Fluvi- 

 ales and Araceae, as these stand in the 'London Catalogue 

 of British Plants,' together with Restiaceae, Juncaceae, 

 Cyperaceae, Gramina, Filices, and Pteridioides ; the last 

 mixed group including Lycopodium, Isoetes, Pilularia, 

 and Equisetum. Taken together, these orders include up- 

 wards of three hundred species, that is, rather less than 

 half the number treated in the present volume.
