lanceolate, glossy, nearly black ; st. 6-9 in. 1., naked, glossy ; fr. 6-18 in. 1., 

 8-12 in. br., cut down to a broadly-winged rachis into nearly entire acuminate 

 lobes 4-6 in. 1., -1 in. br., the lowest pair deflexed ; main veins distinct to the 

 edge ; areolce fine, with copious free veinlets ; sori in single rows near the midrib. 

 Hk. Sp. 5. p. 88. 



Hab. N. India, up to 10,000 ft. Resembles P. trifidum, but the pinnae reach down 

 deeper, and the main veins are closer and more distinct. 



372. P. (Phym.) longissimum, Blume ; rhizome wide-creeping, the scales large, 

 ovate, brown, adpressed ; st. 12-18 in. 1., firm, glossy ; fr. 1-4 ft. 1., 6-12 in. br., 

 cut down very nearly to the rachis into numerous erecto -patent acuminate 

 linear subentire lobes 4-8 in. L, -^ in. br. ; texture coriaceous ; both sides naked ; 

 veins forming large distinct costular areolae and beyond them smaller irregular 

 ones, both with free veinlets ; sori in close single rows near the midrib, forming 

 distinct papillae on the upper surface. Hk. Sp. 5. p. 89. 



Hab. N. India, Neilgherries, Malaccas, Philippines, Formosa. M. Deplanche sends 

 from New Caledonia a plant that agrees with this, except that the sori are submarginal. 



ft Drynaria, Bory. Fronds with either a separate sterile frond or the base of 

 the ordinary one pinnatifid like a sessile oak- leaf, brownish in colour and rigid in 

 texture. Sp. 373-383. 



A. Sterile frond not separate. Sp. 373-375. 



373. P. (Dryn.) Heracleum, Kze. ; rhizome stout, the scales long, silky, 

 fibrillose, bright-brown ; fr. 3-6 ft. L, 2 ft. or more br., the base with a cordate 

 lobed wing 3-4 in. br., the upper part cut down to a broadly-winged rachis into 

 entire acute lobes, which are often 12-18 in. 1., 3-4 in. br. ; texture rigid ; both 

 sides naked ; main veins distinct to the edge, with 6-8 irregular quadrangular 

 areolse between the midrib and edge enclosing smaller ones with copious free 

 veinlets ; sori small, copious, scattered, slightly immersed. Hk. Sp. 5. p. 93.

Hab. Java and Philippines. 



374. P. (Dryn.) Meyenianum, Schott. ; rhizome very stout, the scales \ in. 1., 

 linear, crisped, bright-ferruginous ; fr. 2-3 ft. L, 8-12 in. br., the lower part cut 

 down nearly to the rachis into erecto-patent linear-oblong blunt entire lobes 

 3-6 in. 1., ^-1 in. br., the upper part pinnate, with numerous close pinnae 4-8 

 in. 1., which consist only of a firm midrib, with a row of small round lobes on 

 both sides, each with a sorus that covers it ; texture of the barren lobes coria- 

 ceous, the main veins distinct, the copious areolae with free veinlets. Hk. Sp. 5.

Hab. Philippines. 



375. P. (Dryn.) conjugatum. Lam.; rhizome very thick, densely matted with 

 long linear crisped bright-brown scales ; fr. arranged in a circle, 2-4 ft. 1., 12-18 

 in. br., the stem with a lobed wing 2-4 in. br. on each side at the base, which is 

 narrowed and more deeply lobed upwards, passing gradually into the frond, 

 which is cut down nearly to the rachis throughout into entire erecto-patent 

 pinnce 4-8 in. 1., 1-1^ in. br. ; texture rigid ; both sides naked ; main veins 

 distinct to the edge, the transverse veinlets forming about 6 quadrangular 

 areolse between the midrib and edge ; the sori in a single row close to the anterior 

 main vein, sometimes confluent. P. coronans, Wall. Hk. Sp. 5. p. 95. Fil.
