clothed at the base with very large, glossy scales of a dark brown colour, but 

 showing a pale fringe at the margin. The ample fronds are tripinnate (three 

 times divided to the midrib) ; 

 their leaflets, 12in. to 14in. long, 

 are puinate except at the ex- 

 tremity, of a somewhat leathery 

 texture, and hairy on both sides. 

 The rachises (stalks of the leafy 

 portion) are very hairy and 

 slightly winged, and the ultimate 

 leafits or lobes, Jin. long, have 

 their margins recurved and 

 sharply dented. The al^undant 

 sori (spore masses) are disposed 

 one to each lobe, and partly 

 covered by a large, round, 

 c up - shaped involucre . — Hooker ,

 A very handsome species, 

 native of Brazil, with ample 

 fronds three times divided to 

 the midrib, and borne on short, 

 rough stalks of a peculiar grey 

 colour, having at their base 

 narrow scales of a dark brown 

 colour. The oblong-spear-shaped 

 leaflets are Ift. to lift, long in 

 the middle of the frond ; the 

 lowest are dimorphous (of two 

 forms), with pinnate segments. 



The pinnules (leafits). Sin. to 4in. long, are cut down to the midrib below 

 into bluntish, sickle- shaped lobes, the barren ones closely set, the fertile ones
