entire ; texture subcoriaceous ; both sides naked ; veins very distinct, the main 

 ones branching and becoming lost before they quite reach the edge, including 

 irregular rather large areolae with a few free veinlets ; sori in a very irregular 

 row between each main vein, often confluent. Hk. Sp. 5. p. 73. Colysis, Presl. 



Hab. N. India (up to 6,000 ft.) and Neilgherries.

 in. 1., l-3 in. br., narrowed to both ends ; texture subcoriaceous ; both sides 

 naked ; main veins distinct nearly to the edge, the areolse fine, close, copious and 

 free veinlets abundant ; sori irregularly uniserial between the main veins, few, 

 but often confluent. Lk. Sp. 5. p. 72. 



Hab. Japan and Tsus-Sima. 



** Fronds variously lobed but not regularly pinnatift d or pinnate. Sp. 345-353. 

 f Fronds not in two halves. Sp. 345-350. 



345. P. (Phym.) crispatum, Hk. ; st. tufted, slender, 1-2 in. 1., clothed with 

 soft spreading hairs ; fr. pendent, 6-18 in. 1., ^-| in. br., ligulate, nearly entire 

 or bluntly lobed a quarter or even halfway down to the midrib ; texture sub- 

 coriaceous ; both sides thinly clothed with soft hairs ; veins in pinnated groups, 

 the veinlets forked and uniting with those of the next group ; sori dorsal, 2-6 to 

 each lobe, small, quite immersed. Hk. Sp. 5. p. 1. Glyphotsenium, J. Sin. 



Hab. Panama, Seemann, 995. Differs from Phymatodes by its regular pinnated veins, 

 and from Goniophlebium by being without free veins, and by its dorsal sori.

 ovate, with a deep basal sinus, the edge sinuated ; texture coriaceous ; both sides 

 naked ; main veins distinct to the edge ; areolce fine, copious, distinct ; sori 

 small, copious, scattered irregularly. Ilk. Sp. 5. p. 73. t. 285. B. 



Hab. Borneo, Ldbb. A very distinct species, with fronds like the leaves of Vitis 

 Labrusca. 



347. P. (Phym.) bifrons, Hk. ; rhizome woody, but rather slender, branched, 

 tortuose, nearly naked ; barren fr. sessile, 3-4 in. 1., 1 in. br., elliptical, narrowed 

 at both ends, with blunt lobes, which reach nearly halfway down ; fertile fr. 

 4-6 in. 1., 2-4 lin. br., short-stalked, entire ; texture papyraceous ; both sides 

 naked ; a midrib to each lobe, with copious areolce between, with free veinlets ; 

 sori large, oblong, placed end to end in a row on each side close to the midrib.

Hab. Ecuador, Jameson, 789. 



348. P. (Phym.) Spectrum, Kaulf. ; rhizome woody, wide-creeping, the scales 

 black, subulate, deciduous ; st. distant, 3-4 in. 1., firm, erect, naked ; fr. 6-9 in. 

 each way, cordate-hastate, the apex acuminate, the lateral lobes rounded or 

 acute, the basal lobes deep, sometimes imbricated, the edge not toothed ; texture 

 firm ; both sides naked ; areolce fine, with copious free veinlets ; sori small, 

 copious, scattered irregularly. Hk. Sp. 5. p. 74. Colysis, J. Sm. 



Hab. Sandwich Isles and Sumatra. 



349. P. (Phym.) hastatum, Thunb. ; rhizome firm, the scales linear, spreading, 

 bright-ferruginous; st. 2-4 in. 1., firm, erect, glossy ; fr. 4-6 in. 1., simple, lan- 

 ceolate, ^-1^ in. br., or 3-lobed, with the lateral lobes like the terminal one
