For the principal part of the above description, as well as for tbe drawing from which the plate has been engraved, 

 I am indebted to the kindness of Henry Colebrooke, Esq. The tree was introduced into the Calcutta garden in 1810, 

 by the late Mr. John Roxburgh, and has at present attained a height of twenty-five feet. It forms at all times a beautiful 

 object, but especially when in flower. The leaves are very large and spreading ; they are disposed in a spiral manner 

 round the branches. It appears from the Hortus Bengalemts that ropes are made from the bark, an object for which 

 its tough and fibrous texture seems to render it especially adapted.

I found this singular and beautiful fern in the dense forest of Oaks and Rhododendrums on Sheopore in Nipal. In 

 1823 I sent specimens to the Hon. the East India Company's Museum, under the designation " Asplenmmf reticnla- 

 tum, an Allantodiaf" Mr. Brown, who at once decided that it was a species oi Allantodia, did me the favour to show
