2. D. macrodonta, Presl, Tetn. Pterid.; J. 8m. Gen. Fti. 



Philipp. ; HooJe. Journ. Bot. 3, p. 396. Polypodium

 Blume, accord, to Reinw. in Herb. J. Sm. Polypo- 

 dium confluens, Wall. East Indies, Malayan Archi-

OBS. In Herbariums and books there is great confusion

The Kew Collection is indebted for this species, as also the 

 beautiful Microlepia platyphylla, and others, to Mr. Robert 

 Kennedy, Florist and Fern-dealer in Covent Garden.

OBS. A plant of this Fern was sent some time ago from Old 

 Calabar to the Eoyal Botanic Garden, Edinburgh, and I am 

 indebted for a specimen of it to Mr. James McNab, the 

 Curator of that truly scientific garden.
