EXOTIC FEENS. 



lU 



sembling the British " Hairy Woodsia." It is easily 

 cultivated, and worthy of attention. Native of North 

 America. 



Haibt Cloak Perk {NotlioMo&na distans) is a rare ever- 

 green fern, suitable for a "Wardian case. The whole 

 plant is very scaly. ' The fronds are from 6 to 8 inches 

 in length, narrow, with nearly triangular deeply-lobed 

 leaflets on each side of the leaf-stalk. The leaflets are 

 hairy, and the whole appearance attractive. It is an 

 Australian species not often to be procured, 



Maeten's GrOLD Feen {Gymnogramma Martensii), The 

 Gold and Silver Perns, though very elegant and attrac- 

 tive, are very tender, and require artificial heat. The 

 present species is more hardy than the generality, and 

 has been recommended for the Wardian case or warm 

 greenhouse, but we cannot speak from experience of the 

 result. This fern is a native of South America, and 

 one of the most golden of the Grold Perns, the under 

 surface of the fronds being densely covered with a rich 

 yellow meal. 



Six- ANGLED Polypody {Folypodium Jiexagonopterurn) . 

 This hardy fern is a native of North America, and is 

 sufficiently distinct from either our Beech or Oak Pern 

 to render it a desirable species for cultivation. The 

 somewhat triangular fronds are from 12 inches in length, 

 and though large for the generality of "Wardian cases, 

 it will thrive in a greenhouse. 



Billardiere's Polypody (Polypodium Billardieri) is 

 an Australian fern which will flourish well in a green- 

 house. The evergreen fronds are about 12 inches in 

 length, proceeding at intervals from a creeping root- 

 stock. Some of the fronds are undivided, others are 

 lobed in a similar manner to the common Polypody. 



Poettjne's Polypody {Brynaria Forfmii). The bright 

 green fronds of this species are strap-shaped and un- 

 divided, and about 10 or 12 inches in length, proceeding 

 at intervals from a creeping root-stock. It is a native 

 of China, and will succeed in a greenhouse.
