 fr. linear-ligulate, simple, 1-1^ ft. 1., -|-f in. br., crispate-repand, narrowed 

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

 naked ; areolce 3-4 serial between midrib and edge, exappendiculate ; sori oblongj 

 immersed, marginal, parallel with the edge, |~ in. apart. 



Hab. Isle of Pines, Milne; New Caledonia, Deplanche, Pancher. 



330*. P. (Phym.) simplicissimum, F. Mull. ; rhizome wide-creeping, as thick 

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

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

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

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

 edge, medial ; areolce 3-4-serial between midrib and edge. P. lanceola, F. M. 

 Fragm. 7. p. 120. 



Hab. Queensland ; communicated by Baron von Mueller. 



332*. P. (Phym.) sclligueoides, Baker ; rhizome firm, glaucous, wide-creeping, 

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

 st. 2-4 in., naked, stramineous; fr. lanceolate or oblanceolate, 5-6 in." 1., 10-14 

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

 coriaceous ; surfaces naked ; veins erecto-patent, distinct to the edge, 1^-2 lines 

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

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



Hab. New Caledonia, Deplanche, Pancher, Richards. 



338*. P. (Phym.) exsul, Mett.; rhizome wide-creeping, as thick as a quill; 

 scales broad, reddish ; fr. lanceolate, simple, subentirc, 8-9 in. 1., 2 in. br., 

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

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

 rarely 4-5-seriate between main veins, 6-7-seriate between edge and midrib. 

 Kuhn, Linn. 30. p. 138. 



Hab. South Brazil, Sellout. 



356*. Pleopeltis Stewartii, Beddome, P. B. 1. 1. 204, from Temperate Sikkim,
