 Jap. icon, illustr. I. tab. 7. 



Ehizome creeping, attaining the length of several inches, stout- wiry, 

 flexuous, often loosely branched, sending fibrous roots below, bears a few 

 fronds above, scattered with small tubercles, the basal remains of old 

 stipes, and covered with adpressed minute scales which are os^ate-deltoid eroso- 

 denticulate dark-brown and often deciduous in age. Stipes loosely placed, 

 articulated at the base, hard, naked, smooth, slender, terete, slightly com- 

 pressed, stramineous, with 2 fibro- vascular bandies within, about 1 — 3 cm 

 in length, the base clothed with scales which are narrowly deltoid, lacerate, 

 fuscous-brown, and 1J — 2 mm long. Frond annual, lanceolate, sometimes 

 falcate, about — 23 cm long, 1*— 3 cm broad, gradually attenuated above 

 into an obtusely or sub-acutely acuminate apex, acute at the base and slightly 

 decurrent to the stipe, entire, somewhat crispate, chartaceous, light green, 

 paler beneath, naked but very thinly scaly on the lower portion of the 

 midrib beneath, sparsely and very minutely nigro-punctate on the upper 

 -surface ; midrib slender, prominent above, stramineous ; venation immersed 

 and superficially invisible ; veins erect-patent, not distinct, in distance of 

 about 4 — 6mm one another: veinlets forming irregularly small copious and 

 obliquely angular-suboblong areolae, including a widely divaricately once or 

 twice bifurcate free veinlet with a minute tubercle at the end. Sori oc- 

 cupying the upper portion of the frond, in a single row midway between the 

 midrib and margin or rather .nearer the midrib, a little apart from one 

 another, rounded, 1J — 3 mm in diameter, very shallowly sunk, forming very 

 low protuberances on the back, prominent, yellow, mixed with suborbicular 

 erose and long pedicellate peltate scales among long pedicellate sporangia.
