 Poly-podium attenuatum, E. Br. Prodr. Fl. Nov. Holl. p. 146 ; A. Rich. Bot. Voy.

Hab. Bay of Islands, New Zealand : on trunks and branches of 

 trees; frequent. 



2. DlCTYOPTERIS IRREGULARIS, Presl ? 



D. stipite glahro sulcato; fronde glabra pinnata; pinnis subaltemis 

 oblong o-lanceolatis acuminatis pinnatifidis, laciniis oblongis acutis sub- 

 falcatis sinuato-dentatis ; soris nurnerosis inordinatis. 



Dictyopteris irregularis, Presl, Tent. Pterid. p. 194, t. 8, f. 7 ? 



Hab. Mountains near Banos, Luzon, Philippine Islands. 



Plant about 3 feet high. Stipe glabrous, silicate, and frond about equal 

 in length ; the latter smooth, simply pinnate, and drying black. Pinnae 

 subalternate, remote, and seated on a short petiole, oblong-lanceolate, acu- 

 minate, pinnatifid about half way down to the costa ; the inferior 2 or 

 3 pairs deeply pinnatifid at the base. Segments from 4 to 6 lines 

 broad, oblong, acute, subfalcate, and confluent towards the apex of the 

 pinnae, the margin irregularly and bluntly serrate. The sinuses are 

 rounded at the base, and about half the breadth of the segments. 

 Rhachis slightly compressed, with several shallow furrows in front. 



This agrees very well with the sectional figure of D. irregularis, 

 given in Presl's Tentamen Pteridographise ; but not having seen any 

 description of the species, we have adopted Presl's name with a doubt.
