no. 17 and no. 24 have been distributed under the above name by the U. 8S. E. E. It 
is indeed very similar to A. afine from Mauritius, but that fern does not seem to be 
proliferous. 
8 var. grandipinna. — Frond larger and coriaceous, brittle. Lowest 
pinnules 1!/2—2‘ >< 3/4—1‘, obliquely ovate -lanceolate, obtuse to somewhat 
acute, the edges bluntly serrate and often more deeply notched. Sori as 
in small forms of A. pseudofalcatum. Most pinnae gemmiferous below the 
apex, 
Oahu! Kaala; Molokai or W. Maui! 
~ var. pseudonitidum. — A large fern like 8, but chartaceous, the lowest 
pinnae 5‘ long and 2'/4’ broad at the base, rather long-acuminate, the 
lowest pinnules 1—11/2' long, inciso-lobate as in A. nitidum, Sw., but 
more open angles, obtuse, costulate. Sori pinnate, oblique and straight 
from costule to edge, discreet, not close and crowded at the middle as 
in genuine A. nitidum. 
u! Kahana. — Apparently the same fern comes from Ceylon as A. nitidum, which 
species, however, belongs to the group of A. contiguum. All our fronds bear the characteristic 
gemma near the apex of the main rhachis. The least cut pinnules are exactly like the 
pinnae of A. pseudofalcatum, var. 8. 
18. A. sphenotomum, sp. n. — Scales dark-brown, ovate, with a short 
=) 
dull-green, fleshy when fresh, thick chartaceous when dry, ovate- or 
deltoid-lanceolate, commonly 1—2 ft. long and 8—12‘ or more broad 
‘at the base, gradually decreasing from the basal pinna to the acute pinna- 
tifid apex, tri-, quadripinnate with the pinnae closely set, the lowest 
I'/2—2‘ apart. Rhachis deeply grooved, fibrillose or naked, compressed 
above and in the smaller forms generally bearing a single gemma below 
the apex. Pinnae 16—20 on a side, patent, deltoid-lanceolate, with a 
sharp acumination, 4—8/ long and 1'/2—4' broad at the base, petiolate 
(2—3”), the upper basal pinnule parallel with the main rhachis, the lower 
in the first pinna as long as the upper, 
the secondary rhachides compressed, even margina 
or longer and pedately deflected ; 
3 spreading cuneate-oblong 
dentate at top (or in some Hawaiian forms deeper cut). Veins not close, 
flabellate, with a leading nerve in the larger ultimate pinnules. Sori 
copious, 1—4 to a segment or lobe, rather broad, 11/2—2“ long, always 
opening face to face when more than one. Invol. pale, obtuse at bo 
ends,
