74 POLYPODIUM, § PHYMATODES. 



2^2-3 inches wide cordate or acute entire or sinuato-lobate 

 with a deep sinus at the base forming two rounded lobes, cos- 

 tules evident distant united by transverse veins into areoles 

 which are filled by a network of lesser irregular areoles en- 

 closing free veinlets, sori small copious scattered without order 

 over the surface of the frond. (Tab. CCLXXXV. B.) 



Hab. Borneo, oa limestone rock, Sarawak, Thos. Lobb. — A most distinct well- 

 marked species, with fronds quite resembling the leaves of Vitis Labrusca. 



357. P- (Phymatodes) hastaium, Th. ; caudex stout creep- 

 ing densely mottled above with subulate ferruginous flaccid 

 scales, stipites more or less approximate 1^-6 inches long 

 glabrous glossy, fronds coriaceo-membranaceous glabrous 

 2-6-7 inches long \ an inch to 1^ inch wide from a broad 

 truncate or cordate base simple and oblong acuminated 

 with a black thickened entire or sinuated margin or hastately 

 trilobed or 3-partite with three spreading equal lanceolate 

 lobes, costules very distinct horizontal, veins forming a fine 

 irregular network over the rest of the frond, the small areoles 

 including free veinlets, sori moderately large compital rather 

 distant forming a single series (alternating with the costules) 

 between the costa and the margin. — Thunb. Fl. Jap. iii.^j. 335,

358. P. (Phymatodes) Spectrum, Klfs. ; caudex very long 

 creeping or scandent the younger portions covered with close- 

 pressed imbricating deciduous subulate black scales, stipites 

 distant or approximate 2-5 inches long, fronds firm chartaceo- 

 membranaceous 4-8 inches long (but often broader than long) 

 reniformly or cordately triangular (rarely hastate) the lobes 

 large acuminate the base produced into two broad lobes on 

 each side the stipes and there forming a deep sinus, the lobes 

 so large as not unfrequently to overlap each other at their 

 base, costules evident but slender veniforra united by trans- 

 verse veins forming large areoles filled up with lesser ones 

 which include copious free branched veinlets, the branches 

 divaricated short bearing the sori at the apex or on the back, 

 sori small copious irregularly scattered. — Kavlfs. En. Fil. p. 94.
