122 POLYPODIUM VACCINIFOLIUM. 



a decaying tree be placed in a pot, with a small portion of light 

 compost around it, in which the Fern is planted, it will soon 

 creep around it like ivy, and form an interesting plant. 



Introduced into the Royal Gardens, Kew, by Mr. D. Cameron, 

 in the year 1841. 



A native of the American meridian. West Indies, Brazil, and 

 St. Catharine Island. 



An evergreen stove species. 



P. Daccinifoliimi bears both fertile and sterile fronds, yet it 

 seems doubtful whether any one has succeeded in growing fertile 

 fronds in this country. In gardens, the present species is 

 sometimes seen under the name of P. lycopodioides, the Fern 

 of this name of Linnaeus, Schkuhr, Plumier, and Fee is a Dry- 

 naria, probably it may be a corruption from P. lagopocUoides 

 of Jacquin and Fee. 



The sterile fronds are glabrous, they are simple, of a rounded- 

 oblong form, being decurrent at the base. The colour dark 

 green, and their height only half an inch. The fertile fronds, 

 which I have not seen, are described by Mr. Moore, as simple, 

 linear, glabrous, also decurrent at the base, and are two inches 

 in length. Both barren and fertile fronds are lateral, and are 

 articulated upon a creeping rhizoma, which is thick, brown, 

 and densely covered with scales. 



Sori terminal and uniserial. 



Best known as the GoniopJilehium vaccinifolium. 



My thanks are due to Mr. Ingram, gardener to Earl Brownlow; 

 and to the Curator of the Cambridge Botanic Gardens, for 

 plants of this species, and to Mr. Henderson, of Wentworth, 

 for fronds. 



It is in the Fern Catalogues of Messrs. Rollisson, of Tooting; 

 Veitch, Jun., of Exeter; Cooling, of Derby; Masters, of Canter- 

 bury; and Booth and Son, of Hamburg. 



The illustration is from the specimen forwarded by Mr. Hen- 

 derson, of Wentworth.
