48. POLYPODIUM, PHYMATODES. 365 



Hab. Samoa, Powell, 135. Lobes narrower and more numerous than in P. nigrescens, 

 the veins different, and sori not immersed. 



366. P. (Phym.) dilatatum, Wall. ; rhizome thick, woody, the scales large, 

 ovate, dull-brown ; st. 1 ft. or more 1., with a narrow decurrent wing reaching 

 nearly down to the base ; fr. 1^-3 ft. 1., 1 ft. or more br., cut down within 

 j-l in. of the rachis into acuminate entire erecto-patent lobes 4-8 in. 1., ^-1^ in*- 

 br. ; texture papyraceous ; both sides naked ; main veins fine, wavy, falling 

 rather short of the edge, with copious fine areolse with free veinlets ; sori small, 

 copious, scattered irregularly, often confluent. Hk. Sp. 5. p. 85. 



Hab. N. India (up to 6,000 ft.), Malaccas, Samoa. Habit of the two preceding, but 

 the sori minute and scattered irregularly. 



367. P. (Phym.) laciniatum, Blume ; rhizome wide-creeping, the scales lan- 

 ceolate, ciliated, bright-ferruginous ; st. 6-12 in. 1., firm, erect, glossy ; fr. 12-18 

 in. 1., 1 ft. or more br., cut down throughout to a narrowly-winged rachis into 

 lobes 6-9 in. 1., ^-f in. br., the point much acuminated, the edge slightly undu- 

 lated, the lower ones deflexed ; texture subcoriaceous ; both sides naked ; main 

 veins distinct to the edge ; areolce fine, with copious free veinlets ; sori uniserial, 

 immersed. Hk. Sp. 5. p. 87. 



Hab. Java. P. molascens, Mett., is said to differ by its broader entire scales, coriaceous 

 texture, immersed veins, and sori sunk in a deep pit. 



368. P. (Phym.) alatum, Hk. ; rhizome woody, scaleless ; st. 12-18 in. 1., firm, 

 erect; fr. l|-2 ft. 1., 10-12 in. br., cut down nearly to the rachis below, within 

 ^ in. above, into numerous erecto-patent repand linear-oblong acuminate lobes 

 6-8 in. 1., 1 in. or more br. ; texture papyraceo-herbaceous ; both sides naked ; 

 main veins distinct to the edge, with copious fine areolae with free veinlets ; sori 

 rather small, in rows of 3-4 near the main veins. Hk. Sp. 5. p. 85. 



Hab. Fiji, Brackenridge, Seemann. Very like dilatatum in habit and texture, but the 

 main veins straight, and the sori, though small, in 2 regular rows near them. 



369. P. (Phym.) glaucum^ Kze. ; rhizome stout, the scales long, dense, fibrillose, 

 dark glossy-brown ; st. 6-12 in. 1., firm, erect, glossy ; fr. 12-18 in. 1., 6-8 in. br., 

 cut down throughout to a broadly-winged rachis into erecto-patent entire 

 acuminate lobes 4-5 in. 1., ^-f in. br. ; texture very coriaceous ; both sides naked ; 

 no distinct main veins and areolse quite hidden ; sori forming single rows close 

 to the midrib. Hk. Sp. 5. p. 88. 



Hab. Philippines. Eesembles some of the forms of P. aureum in texture and general 

 habit. 



370. P. (Phym.) Zomarioides, Kunze ; rhizome forming a thick wide-spreading 

 crust, thickly clothed with small peltate scales, ferruginous in the centre, with a 

 broad scariose border; st. 2-4 in. 1., firm, erect ; fr. 12-18 in. 1., 4-6 in. br., the 

 barren one cut down within ^-J in. of the rachis into close horizontal oblong 

 entire blunt lobes f in. br. ; the fertile one cut nearly to the rachis throughout, 

 with more numerous lobes, |--f in. br. ; texture coriaceous ; surfaces naked ; 

 veins immersed, irregular ; areolce fine, with copious free veinlets ; sori com- 

 pletely immersed, round or oblong, forming two close rows near the midrib. 

 Hk. Sp. 5. p. 79. 



Hab. Java, Borneo, Philippines. Lecanopteris carnosa, Blume, appears to be an 

 abnormal form of this, with the lobes intermediate in character between tbose of the 

 typical barren and fertile frond, with large sori in very distinct marginal pits. Agrees 

 with P. sinuosum in its very peculiar rhizome, the barren frond having quite the habit of 

 a pinnatifid Lomaria. 



371. P. (Phym.) ebcnipes, Hk. ; rhizome stout, wide-creeping, the scales large,
