 creeping aboveground paleacous with ovato-acuminate black- 

 brown scales at length glabrous, fronds 1-H foot long 3-6

 the base and decurrent at the insertion of the stipes, at the 

 apex gradually and long-acuminated the margin entire and 

 revolute (most so when dry), primary veins immersed directed 

 at an acute angle from the costa forming areoles which are 

 bi-triseriate, sori bi-triseriate in the direction of the costa 

 biseriate between the costules" {Mett en. under P. teeniosum).

 to specimens varying in length and breadth of the fronds, in texture, and I fear, 

 too, not a little in the nature of the venation, the large costal areoles being some- 

 times the only ones with a few free marginal veinlets, at other times there are 2-3 

 imperfectly arranged series with 1-2 sonferous included veinlets ; hence the sori are 

 sometimes in a single series, quite as in Goniophlebium, at other times they are 

 copious and scattered. Some of the broader-fronded and more membranaceous 

 states, myself and others are hardly able to distinguish from P.fasciale. — Seethe
