FLORA OP NEW ZEALAND.

Filices.^ 



venulse Iiberse nullae. Capsules pilis articulatis immixtse. — Ehizoma validum, repens v. hrevissimum. Frondes 

 simplices, rhizomate elongato, repente, clistantes, v. rhizomate brevissimo, caspitosa. 



The simple coriaceous fronds, with internal anastomosing veins, that cannot be seen without maceration and 

 dissection, together with the large, naked, superficial sori, and the capsules mixed with jointed hairs, distinguish B. 

 lanceolata from its New Zealand allies. — Rhizome very short, covered with broad, imbricate, membranous palese; 

 roots brown or black, woolly. Fronds perfectly glabrous, tufted, 2-12 inches long, lanceolate, acuminate, nar- 

 rowed gradually into a short margined stipes, i-f inch broad. Sort large, globose, in one series on each side of 

 and near the eosta. Receptacle sunk in a pit of the frond.— There is a specimen of this plant in Hook. Herb., marked 

 as coming from the Blue Mountains of Australia, but I consider this habitat doubtful. (Name from oWw, a net- 

 work; in allusion to the reticulated veins.)

Gen. XXIII. AETHEOPTEEIS, /. Sm. MSS. 



Sori uniseriales, dorsales, globosi, (in sp. Nov. Zel. nudi,) superficiales, venulis terminales. Vena fur- 

 catse, libera? ; venulse apice incrassatas, marginem non attingentes. — Ehizoma repens, squamosum. Prondes 

 alternce, pinnatee. Pinna? rachi articulated. Stipes iasi articulatus. 



I have adopted this genus from the manuscripts of Mr. Smith, who has kindly given me its characters, and 

 adds that its congeners are the Australian Neplrodium obliteratum, Br. Prodr., and Nephrolepis triehomanoides, J. 

 Sm., a Luzon Pern. The two latter Perns have involucres, but in all other respects are considered by Mr. Smith 

 to differ from the genera in which they have been placed, and to form a truly natural genus with the New Zealand 

 A. lenella. The latter cannot be associated naturally with any other species of Polypodium. — A perfectly glabrous, 

 climbing, pinnate Pern, found also in Eastern Australia.— Rhizome very long, slender, rigid, wiry, scaly. Fronds 

 scattered, pendulous, jointed above the base, 1-2 feet long, lanceolate, pinnate. ' Pitmrn membranous, alternate, 

 distant, 2-3 inches long, linear-lanceolate (sometimes forked), narrowed to a blunt point, obliquely cuneate at the 

 base, jointed on to the rachis; margin sinuate; costa slender; veins once or twice forked, oblique, all free; veinlets 

 terminating in a swollen point within the margin. Sori globose, in one series on each side the costa, near the 

 margin, each, placed at the apex of a veinlet. (Name from ap6po<s, a joint, and wrepis, a fern ; from the articulate 

 pinnules and stipes.) 



1. xlrthropteris tenella, J. Sm. ; frondibus glaberrimis pendulis lineari-lanceolatis pinnatis, pinnis mem- 

 branaceis alternis lineari-lanceolatis in apicem obtusum angustatis margine sinuatis basi oblique rotun- 

 dafo-cuneatis brevissime stipitatis, soris nudis submarginalibus. — J. Sm. MSS. Polypodium tenellum,
