 and narrow, acutely long-acuminate, resembling those of PL. rupesiris MOORE. 

 Fronds not liastate.

 acute or subaciiminate, resembling those of PL triqiietra V A. V. R. Fronds 

 not rarely hastato-3-fid ; basai segments subsimilar to the central one but

The spécimen on which CHRIST based this iiame is unknown to 

 me but the spécimens occurring up till now under this name in the 

 Buitenzorg Herbarium are but narrow forms of P. sumatraniim BK. ; 

 the spécimens formerly gathered and determined by RacîBORSKI as 

 P. siibpleiosonini Rac. are represented by both broad and narrow forms; 

 the broader ones agrée exactly with the original P. sumatraniim Bk. 

 (BECCARI No. 448) and the narrower ones with the spécimens of P. diplo- 

 sorum quoted.

BuNNEMEljER's No. 6732 from Lingga (Mt. Daik) differs from the 

 Bangka plant in having the stipes somewhat longer, with the hairs deci- 

 duous, the fronds rather gradually caudate-acuminate, the sori subsuperficial, 

 to 7 on a side, the réceptacle rather oblong. — Epiphytical in forest, ait.
