Asplenium — Spleenwort. 



Angustifolium — Narrow-leaved. 



In the Section Euasplenium of Authors. 



An elegant rare Fern, which appears to have been introduced 

 into the E-oyal Gardens, Kew, in the year 1812, but which is 

 still one of our rarest cultivated exotic species. 



Unlike most of the other Aspleniums, the barren and fertile 

 fronds are strikingly different, so much so as to give the plant 

 a character distinct from other species of the genus Asplenium- 



A hardy deciduous Fern, readily cultivated. 



Native of North America. 



The fronds, which are glabrous, are slender, lanceolate in 

 form, pinnate, the pinnae being linear -lanceolate and cordate at 

 the base. Subauriculate, membranous, and being slightly crenu- 

 late on the margin. Fronds terminal. The fertile fronds are 

 narrower and shorter. 



Sori copious, a single oblique row on each side the midrib 

 of each pinnae, prominent, and eventually becoming confluent.
