COPELAND. 
and everywhere foliaceous, the final branches up to 25 cm long; segments 
10 to Id mm long, 3 mm wide, confluent, obtuse, falcate or not horizontal, 
revolute when dried, coriaceous, glabrous unless at the base of the costa 
beneath, more or less glaucous beneath : sporangia 3 or 4 in a sorus. 
Malaya, on high mountains. 
7. Gleichenia loheri Christ. 
Creeping stem and bases of stipes clothed with dark-brown, lanceolate, 
entire palese 5 mm long, stipes about 30 cm high; raeliis bearing paired 
pinnae, and the lowest of these, in well-developed specimens, also with 1 
or 2 pairs below the final fork, the axes everywhere foliaceous or bearing- 
segments only down to the lowest fork, clothed with tawny, lanceolate, 
subulate, lacerate-ciliate spreading scales; branches finally twice forked 
at an acute angle, the ultimate branches up to 20 cm long; segments not 
horizontal, barely confluent, deltoid-lanceolate, acute, 2.5 to 3 mm wide 
at the base, 12 mm long, revolute in drying, coriaceous, dark-brownish- 
green above, paler beneath but not glaucous, glabrous except on the cos- 
tules beneath. 
Luzon, Mount Banajao. 
8. Gleichenia laevigata (Willd) Hook. 
Rhizome naked, woody; frond up to 150 cm or more high, stipe and 
rachis brown, slender, naked, smooth, marked above by two sharp lines, 
forked at the top, and below this bearing 0 to 5 pairs of pinna?, in whose 
axils and at the apex some small, congested, green bracts are sometimes 
found; pinna? 2 to 5 times forked, everywhere foliaceous, widely divar- 
icate, ultimate branches up to 20 cm long, axes glabrous or bearing very 
minute, spreading scales; segments at right angles, connected by a narrow 
wing, up to 4 cm long, 2 mm wide, straight, entire, obtuse, herbaceous or 
fairly coriaceous, more or less glaucous beneath, glabrous unless on the 
costa beneath ; sori of 3 or 4 sporangia, sometimes subtended by lacerate 
squamules. 
Malaya, widespread at mean altitudes. 
9. Gleichenia oceanica Kuhn. 
Frond up to 2 m high ; pinna? in small plants a single pair at the top, 
but in large specimens several pairs lower down, several times dicho- 
tomous at an acute angle, ultimate branches 10 cm or more long, deeply 
pinnatifid, rachises densely clothed with lanceolate, ferruginous, fimbriate 
scales; segments on all (or all but the lowest) axes of the pinnae, standing 
at an acute angle, close, short, 2 mm wide, acute, abruptly reduced toward 
the apex of the branch, membranaceous, glaucous beneath; sori medial. 
I have followed Christ in framing this diagnosis, as the species is known in 
Malaya only by the Celebes plant determined by him. Kuhn says explicitly that 
the segments stand at a right angle, and are obtuse, and up to 24 mm long. 
Celebes, Polynesia.
