 Wall. Hk.Sp.5.p.-u. 



Hab. N. India (up to 7,000 ft.) to Ceylon, China, Japan. 



856. P. (Phym.) malacodon, Hk. ; rhizome rather slender, the scales lan- 

 ceolate-acuminate, brown or nearly black ; st. 4-6 in. 1., slender, glossy ; fr. 

 6-15 in. 1., 5-6 in. br., with a linear or linear-oblong subentLre or repand and 

 finely-toothed acuminate terminal Ide 3-4 in. 1., ^-j in. br., and 1-4 smaller 

 lateral ones on each side, which are more or less confluent at the base ; texture 

 papyraceous or subcoriaceous ; both ^es naked ; main veins fine but distinct, 

 the areolae fine and clearly visible, with copious free veinlets ; sori in a 

 single row on each side, nearer the midrib than the edge. — Hk. Sp. 5. p. 87- P- 

 cyrtoloba, J. Sm. 



Hab. N. India, np to 12-13,000 ft. — Very near the last, but thinner in texture, the 

 pinnse deeper, and often finely toothed. 



357. P. (Phym.) incurvatum, Blume ; rhizome woody, the scales adpressed ; 

 yr. dimorphous, the barren ones 6-9 in. each way, deltoid, ternate or pinnatifid, 

 with broad lanceolate-acuminate entire lobes, the stem firm, glossy, 6-9 in. 1. ; 

 fertile fr. larger, cut down nearly or below quite to the rachis into erecto-patent 



entire distant lobes 4-8 in. 1., |-f in. br., the lowest sometimes forked, the st. 

 lJ-2 ft. 1. ; texture very coriaceous ; both sides naked ; main veins distinct to the 

 edge ; the uniserial sori quite immersed, and forming prominent papillae on the 

 upper surface. — Uk. Sp. 5. p. 77. 



Hab. Malaccas. — ^Well distingoiahed by its very coriaceous usually ternate barren 

 frond, with deltoid lobes. 



358. P. (Phym.) angustum, Mett. ; rhizome firm, the scales brown, linear, 

 crisped ; St. 2-5 in. 1., firm, erect ; fr. 6-9 in. each way, with a linear terminal 

 lobe 4-6 in. 1., J-f in. br., and several similar erecto-patent lobes on each side, 

 which reach down nearly or quite to the rachis and are dilated at the base ; 

 texture coriaceous ; under sufface furfuraceous, with minute scattered peltate 

 scales ; veins obscure ; sori prominent, in a row on each side the midrib. — Hk. 

 Sp. 5. p. 76. 



Hab. Mexico, Guatemala, W. Indies, S. Brazil. — The original PUopeltis of Humboldt. 

 The typical plant is sometimes subdigitate ; P. sectifrons, Kze. {Drynaria elctstica, F^e), 

 is a more fully pinnate form than usual ; and D. stenoloma, F^e, a form with the lobes 

 only ^ in. br. 



359. P. (Phym.) insigne, Blnme ; rhizome slender, the scales linear, dull- 

 brown ; St. 2-4 in. 1., slender, erect, naked ; fr. 6-9 in. 1., 4-6 in. br., with an 

 entire lanceolate-acuminate terminal lobe 2-3 in. 1., ^ in. or more br., and 2-4 

 similar ones on each side, which reach down within J in. of the rachis and below 

 them a long narrow decurrent wing to the stem ; texture fiim-herbaceous ; both 

 sides naked ; veins fine, irregular, with free veinlets ; sori small, scattered 

 irregularly. — Hk. Sp. 5. p. 78. 



Hab. Java, Philippines, and Malacca.
