14 POLYP(>DIUM SPORADOCARPUM. 



Introduced into the Royal Gardens, Kew, in the year 1843, 

 having been forwarded by Mr. D. Cameron. 



Fronds glaucous, pinnatifid; outline somewhat oval, with stiff 

 coriaceous, blunt, nearly lanceolate repand segments, having 

 the margins entire. Young fronds, when partially expanded, 

 very nearly resemble the wings of a bat. 



Veins very pale and semitransparent, with club-shaped apices. 



On the upper side of the frond, immediately within the 

 margin, a row of white deciduous scales. 



Usually eight or nine pairs of segments, with a terminal one. 



Sori large and conspicuous, uniserial; colour bright yellowish 

 brown; mostly about twenty-eight to thirty-two pairs on each 

 segment. 



Length of frond three feet; colour a milky green. 



Stipes very smooth, brownish green, half the length of the 

 frond, and having few long white scales near the base. 



Fronds lateral, being articulated on a thick, glaucous, scaly, 

 creeping rhizoma. 



For plants of this species I am indebted to Mr. Henderson, 

 of Wentworth; and for fronds to the same gentleman, and to 

 Mr. Norman, of Hull. 



It may be procured of the following Nurserymen: — Masters, 

 of Canterbury; Yeitch, of Chelsea; A. Henderson, of Pine-apple 

 Place; Stansfield, of Todmorden; Kennedy, of Co vent Garden; 

 Kollisson, of Tooting; Osborn, of Fulham; and Booth, of Ham- 

 burg. 



The illustration is from a plant in my own collection.
