296 ON A COLLECTION OF FERNS FROM THE SOLOMON ISLANDS. 
a foot long and broad, bright green and glabrous on both surfaces. 
Distinct pinne not more than 4-jugate, erecto-patent, all (except 
the lowest) joined by their conspicuously decurrent bases. Lowest 
pair of pinne largest, lanceolate, 8-9 in. long, 13-14 in. broad, 
lobed about halfway down to their midribs in the middle, with 
obtuse erecto-patent ovate-oblong segments. Main veins erecto- 
patent, 3-3 in. apart, straight and distinct from midrib to margin. 
Sori large, orbicular, in regular rows near the main veins. 
This comes nearest the common Polynesian JN. decurrens ; but 
the wing to the rhachis does not reach down to the basal pinne 
or run down the stipe. The pinn& are narrower and deeply pin- 
natifid, and their main veins more distant.

Fruticosa, frondibus amplis deltoideis tripinnatifidis, pinnis oblongo- 
lanceolatis, pinnulis lanceolatis acuminatis sessilibus, segmentis tertiariis 
oblongis contiguis serratis, venis pinnatis, venulis simplicibus 6—7-jugis, 
soris oblongis parallelis intramarginalibus. 
Frond ample, tripinnatifid, moderately firm in texture, green 
and glabrous on both surfaces, the rhachises naked. Pinne 
oblong-lanceolate, the lower 1-14 ft. long, 6-8 in. broad. Pin- 
nules sessile, patent, lanceolate, acuminate, cut down within a 
short distance of the midrib into contiguous oblong distinetly 
serrated tertiary segments 4 in. broad. Veins pinnate in the 
tertiary segments, with 6-7-jugate simple distinct ascending 
veinlets. Sori oblong, parallel, beginning at the midrib, but 
ending a space from the margin. 
The most interesting novelty in the collection, with the habit 
precisely of the large Diplazioid Asplenia A. maximum of the 
Old World (with which, no doubt, A. latifolium must be joined), 
and A. radicans, Schk. (A. dubium, Mett.), of America.

Fronds trifoliate, and one specimen quite simple, but y et 
completely soriferous, and closely resembling G. Wallichii.
