144 NEPHRODIUAI, § LASTREA. 



ultimate pinnules distant linear-oblong acute sinuate-dentate 

 or subpinnatifid, the sinuses often having a sharp lobule 

 which forms a zigzag wing to the costa, veinlets distant sim- 

 ple or forked, sori generally one to each lobe of the segment, 

 involucre very cellular cordato-reniform, the margin with 

 glandular hairs. Hook. 2d Cent, of Ferns, t. 62. 



Hab. Wooded mountains of Naviti Levu, Fiji Islands, Milne.— \ cannot refer 

 this to any hitherto described species, nor does it appear to lie known to Bracken- 

 ridge. The stipes and n;ain rachises are singularly ebeueous, and the wing, if I 

 may so say, of the main cost;e, which unites the segments, has a zigzag appear- 

 ance, from the frequent presence of an angle or short lobe in the broad sinuses of 

 the segments. 



141. N. (Lastrea) tenu\folium.. Hook.; "stipes angular 

 squamoso-hirsute, fronds membranaceous subtripinnate at 

 the base above bipinnate, the apex pinnatifid^ pinnules ob- 

 long-lanceolate acute pinnato-partite with the base oblique 

 adnato-decurrent, the segments linear-oblong lower ones in- 

 ciso-serrate, rachis costa and veins on both sides paleaceous 

 glandulosn-hirsute, sori small, involucre reniform lacerate."

Hab. Ovalau, Fiji Islands, in mountain forests, Brackenridge, Milne. — I have 

 seen no authentic specimen of this species, but my specimens collected by Milne, 

 in similar localities of Ovalau, sufficiently correspond with the description. It pos- 

 sesses no peculiarly tranchant character. Brackenridge compares it with Aspid. 

 tenuisectum of Blume. 



142. N. (Lastrea) squarnigerum, Hook, et Arn. ; caudex 

 (imperfect) short stout erect, stipites tufted a span to a foot 

 long very paleaceous as well as the rachises with soft ferrugi- 

 nous scales varying in size, fronds 1-1^ foot long membrana- 

 ceous broad-ovate acuminate bi-tripinnate, primary pinnee 

 often opposite 4 inches to a span long broad-oblong or ovate 

 acuminate, uppermost ones sessile pinnatifid, secondary ones 

 oblong obtuse an inch or more long nearly h an inch wide 

 sessile and decurrent more or less pinnatifid at the margin, 

 ultimate pinnules of the same shape but smaller, veinlets 

 distant simple or forked, sori subbiserial between the costule 

 and the margin, involucres reniform very membranaceous 

 cordato-reniform fimbriato-ciliate, custes and costules be- 

 neath densely clothed with ovato-lanceolate subulate close- 

 pressed obtuse scales different from those of the stipes.
