POLYPODIUM HENDERSOm.

PLATE XXXVII. — B. VOL. II. 



Polypodium — Polypody. Hend,ersoni — Named after Mr. Joseph 



Henderson, of Wentworth. 



In the Section Cyrtophlebium of Authors. 



The present Fern is a very distinct species, and although 

 approaching nearest to Polypodium angustifolium of Swartz, 

 which is figured in Vol. I., Plate XLVIII, nevertheless it is 

 strikingly dissimilar from that species. 



The habit of the plant is more erect, the colour of the fronds 

 paler, and although narrower than P. angustifolium, still they 

 scarcely curl round along the edges, as is most frequently the 

 case with that species. The barren fronds are the same size 

 and form as the fertile fronds, whilst in P. angustifolium, the 

 barren frond is three times as broad, and quite dissimilar from 

 those that are fertile. (See engraving on page 80.) 



In searching the different works upon Ferns, I have been 

 unable to recognise the present Fern as one hitherto described, 

 and have therefore ventured to name it P. Ilendersoni.
