 are separated by Mett. and Kuhn, Fil Afr. p. 152. as a species under the name 

 of P. fSckimperianum.

 fr. linear-ligulate, simple, l-\\ ft. 1., |-| in. br., crispate-repand, narrowed 

 gradually to both ends ; texture rigidly" snbcoriaceous ; surfaces bright-green, 

 iiaked ; areolce 3-4 serial between midrib and edge, exappendiculate; sori oblong, 

 immersed, marginal, parallel with the edge, j-j in. apart.

800*. P. (Phym.) siwpVrls-'^imwn, F. Mull. ; rhizome wide-creeping, as thick 

 as a quill ; scales minute, lanceolate-acuminate, bright-brown ; st. 1-1^ in., 

 grey, naked ; fertile fr. linear-ligulate, 3-6 in. 1., 3-4 lin. br., obscurely crenate, 

 narrowed very gradually to both ends, sterile shorter and broader; texture 

 rigidly coriaceous; surfaces naked ; main veins distinct nearly to edge, l|-2 lin. 

 apart ; sori round, superficial, 1-serial between main veins and midrib and 

 edge, medial ; areolcs S-4-serial between midrib and edge. — P. lanceola, F. M. 

 Fragm. I.p. 120. 



Hab. Queensland ; communicated by Baron von Muellei*. 



8-32*. P. {Phym.) selligueoides, Baker; j7i/;:'o;?je firm, glaucous, wide-creeping, 

 under 1 lin. thick ; scales mmnte, adpressed, brown, membranous, oblong, blunt ;

 iin. br., acuminate, narrowed gradually at the base ; texture rigidly sub- 

 coriaceous ; surfaces naked ; veins erecto-patent, distinct to the edge, l-o-2 lines 

 apart ; areolae copious, with free included veinlets ; sori uniserial between the 

 main veins, 1-3, round or oblong, all distant from edge, 



Hab. New Caledonia, Deplanche, Panclw, Iticlucrds. 



338*. P. (Phym.) exstd, ]\Iett. ; rhizome wide-creeping, as thick as a quill ;

 narrowed to both ends ; texture membranous ; surfaces glabrous ; areola? 6-7- 

 seriate between edge and midrib, appendiculate ; sori round, superficial, 2-3-, 

 rarely 4-5-seriate between main veins, C-7-seriate betvreen edge and midrib. — 

 Kiihn, Linn. o(j. p. 183. 



Hab. Sout^ Brazil, Sellow. 



856*. Pleopeltis Stewartii, Beddome, F. B. 1. 1. 204, from Temperate Sikkim,
