scattered but each primary areole has two sori and collec- 

 tively they form about four series parallel with the costa and 

 margin and two parallel with the costules. — Drynaria, Brack.

Hab. Fiji Islands, Brackenridge, Seemann, n. 731. — Allied to P. affine, Bl., 

 and P. dilatatum, but very different from both. 



377- P- (Phymatodes) draconopterum, Hook.; caudex (the 

 only one I possess and of a young plant) thicker than a 

 swan's quill horizontal scaly towards the apex and there bear- 

 ing an erect stipes very stout in mature plants thick as the 

 little finger 2-3 and more feet long deeply sulcated (when dry) 

 scaly below with rather lanceolate firm scales decurrently 

 winged above, frond ample 1^ to 3 and more feet long and 

 perhaps as much broad firm-membranaceous dark-green some- 

 what glossy deeply (or below remotely pinnated with the pinnee 

 united by a wing) lobes or segments often very large a foot 

 long (particularly the terminal one) 4-5 inches and more 

 wide broad-oblong the lowest pair unequal-sided or when 

 mature unequally bipartite all rather suddenly and finely 

 acuminated entire, costules \ an inch or more apart united 

 by distant curved transverse veins, these again are connected 

 by transverse veinlets and their areoles are reticulated with 

 lesser subquadrangular small appendiculated areoles, the ul- 

 timate veins branched free, sori very copious small scattered 

 orbicular dorsal or terminal or compital rarely confluent. —

Hab. New Granada, Purdie, 1845. Turbo, Gulf of Uraba, H. Schott. Tara- 

 pota, Eastern Peru, Spruce, n. 4065, and Ecuador, Chimborazo, alt. 3000 feet. — 

 Although so very fine a species and collected nearly twenty years ago, it met with 

 no describer till an excellent description was given by Mr. D. C. Eaton, in the 

 work above quoted, from Mr. Schott's specimens. It was, indeed, briefly noticed 

 by Mr. J. Smith as a discovery of Mr. Purdie, vvlio refers it to Fee's genus Dryo- 

 menis ; but neither the shape nor arrangement of the sori tally with the charac- 

 ter of the Genus. Mr. Eaton had only imperfect sori, and not unnaturally placed 

 the plant in Euaspidium. 



378. P. (Phymatodes) inenisciicarpon. Hook.; caudex 

 rather stout erect, stipites terminal clustered a sj^an to 1 foot 

 long, frond about as long as the caudex coriaceo-membrana- 

 ceous cordate or oblongo-cordate pinnated, pinni3e 3-9 4-6
