specimens are more slender than Wallich's type more papy- 

 raceous in texture and furnished with a broad white band 

 down the centre of each pinna ; it would be a very pretty plant 

 for cultivation.

13. Pteris excelsa. Specimens collected in the Khasia 

 Hills by Jerdon have the rachis, partial rachis, and midrib finely 

 scaly underneath. Mann sends specimens from the North Cachar 

 Hills, 2,500 feet alt., with the lower pinnae bipartite, and occasional 

 campterioid venation ; excelsa can be easily distinguished from 

 longipinnula by the stipes and rachis being bright chestnut- 

 goloured ; in longipinnula they are bright green or stramineous.
