Hab. Java, Blume, Zollinger. Amboyna {ex Herb. Webb, in Herb, nostr., 

 16-18 inches long, quite sessile, spathulate, obtuse, cordate, and broad-eared 

 at the base). — Except garden specimens, my herbarium only possesses this plant 

 from Amboyna, and even this is marked " P. irioides ?" by Mr. Moore, I am 

 not therefore in a position, with such imperfect materials, to say if the species be 

 truly distinct from the well-known, wide-spread, and very variable P. irioides. 

 The texture of the frond is thinner, the venation coarser and more prominent, 

 and the areoles larger. Neither the figures nor description of P. irioides and P. 

 muscefolium of Blume (and he is the author of the latter species) seem to justify 

 the view of their being distinct. 



346. P. (Phymadictyon) myriocarpum, Metten. ; caudex 

 creeping, stipes none save the winged portion of the rachis, 

 frond firm-membranaceous 2-3 feet long 2-4 inches wide very 

 elongato-lanceolate acuminate long and gradually tapering to 

 tlie very base so as in that sense to be called sessile, entire and 

 not thickened at the margin, costa very prominent beneath, 

 venation manifest slightly prominent beneath, costules dis- 

 tinct distant slender straight stopping short at ^ or | of 

 the way from the costa and there forming a series of very 

 large costal primary areoles, a second series of stout veins 

 forms smaller but still very conspicuous areoles and the 

 space between the second series and the margin is filled 

 up with an irregular network of lesser areoles with copious 

 included free veinlets, sori most abundant minute scattered 

 over the veinlets. — P. myriocarpum, Metten. Polypod. p. 105.

Ilab. Luzon, Cuming, n. 66. Borneo, Sarawak, on limestone, Tkos. Lohb. — 

 This belongs to the same (Microsorous-) group of Polypodium as P. irioides, and 

 the form is quite of that variety, which lias fronds tapering below and loiig-de- 

 current wings upon the stipes ; but if there is any reliance to be placed on the ve- 

 nation, it cannot but be distinct. This is well represented in Mettenius's figure, 

 1. c. My specimen from Borneo is twice as I)road as those from Luzon, and the 

 primary costal areole 1 ^ inch long and | of an inch broad. One frond from 

 Cuming is irregularly pinnatiiid with segments, some of which are 7 inches long 

 and ^ of an inch wide, but I look upon it as a lusus naturce.
