or half-shield, an approach to the more distinct shield of P. grande), and this is 

 convex and rises or inclines upwards at the margin, giving a very peculiar cha- 

 racter to the fertile fronds. Our specimens all hear two or more rarely three sori 

 on each of the fronds. 



5. P. b'iforme, Bl. ; fronds ample bifarious at length gla- 

 brous ; sterile ones iml)ricated very thick and corky towards 

 the base subrotund but very varied in circumscription lobed 

 and sinuated at the margin coarsely reticulato-venose ; fer- 

 tile fronds (geminate ?) rather long-stipitate of great size 5-G 

 and more feet long ! from a subcuneate base repeatedly di- 

 chotomouSj the segments loriform flaccid and pendent, fer- 

 tile segments quite different from the rest forming a large 

 reniform stipitate shield-like receptacle 6-8 inches or more 

 in diameter wholly soriferous beneath except at the margin.

 being changed into a large, reniform, shield-lii<e receptacle, (luite different from 

 the rest of the fertile frond ; hence Swartz's name of biforme. Wallich's name 

 o( fuciforme would be more appropriate, for some of the yonn;; segments of the 

 fertile fronds much resemble Fnciis nodosus.

 which is prolonged and attached at the summit to a hemi-
