each side, often only the lowest united. Sori nearly terminal on the veins, 

 present on all the veins, or on all except the 1 — 2 low^er ones, not rarely 

 immersed and visible as punctiform dots on the upper surface.

 currens, Bk., Hk. Bk., Syn. Fil., 290; Aspidium prociirrens, MetL, Ann. Mus. 

 Bot. L. B., I, 251. 



Rhizome wide-creeping, clothed sparingly with deciduous, linear scales. 

 Stipes approximate, up to 45—60 c.M. long, slightly and deciduously scaly 

 towards the base. Fronds deltoid to deltoid-lanceolate, 45 c.M. or more long, 

 nearly 30 c.M broad; rachis more or less hairy or nearly glabrous. Pinnae 

 12 — 30 on each side, patent, the lowest sometimes a little smaller and deflexed, 

 narrow-linear, acuminate, + 1 ^2 c.M. broad, cut down nearly to the costa 

 into narrow, oblong, entire lobes, the lowest of which often suddenly reduced 

 in size. Texture papyraceo-membranaceous, more or less hairy or nearly 

 glabrous, often furnished beneath with golden pubescence in the way of close, 

 pressed hairs or oblong dots more on the paranchyma than on the veins ; veins in 

 6 — 12 pairs, all simple, the lowest pair only anastomosing. Sori medial on 

 the veins; indusium naked or hairy. — Very like D. parasitica, 0. Ktze, 

 (Bk.).

 XV 135. 



Rhizome creeping, the extremity clothed with few, small scales. Stipes 

 1 — 8 c.M. apart, 80—120 c.M. long, livid, naked, glossy. Fronds linear- 

 lanceolate, to 100 c.M. long, 20 — 45 c.M. broad. Pinnae numerous (20 — 35 

 on each side), 2 — 2^/^ c.M. broad, sessile, slightly narrowed towards the base, 

 linear-lanceolate, acuminate, the edge cut down ^/j of the way to the costa 

 into oblique, oblong, bluntish or acute lobes. Lobes straight or subfalcate, 

 10 — 14 m.M. long, ± 4 m.M. broad, with a distinct sinus between them. 

 Texture herbaceous; the edges and both surfaces more or less hairy on the 

 costae and veins; veins 8 — 16 on a side, often only the lowest ones anasto- 

 mosing. Sori ± 6 — 9 on each side of the main veins, medial, not occupying 

 the higher veins. 



Java, Celebes.
