lanceolate, lowest pair largest, and most developed on the inferior side, 

 those above these rather deeper on the superior side, acuminate and 

 sharply serrate at the point as is the apex, of the frond, especially in 

 the barren state ; interior pinnule of all on the upper-side, the 

 corresponding one of the inferior side being absent ; tertiary segments 

 lobed, pinnatifid or fully pinnate at the base ; final one oblong-lanceo- 

 late, 2-4 li. 1. li. w. cuneate at the base when free, the point acute 

 and sharply toothed in the barren but usually entire in the fertile 

 fronds ; veins pinnate or forked in the final segments ; sori more or less 

 medial on the veins ; involucres cordate, pale coriaceous, ample some- 

 what ciliate. — Annals of Botany, Vol. 5, 1891. 



Gathered by Mr. Hart, a few years ago on the St. Andrew 

 Mountains in the region of Mt. Moses, 3,000 ft. alt., intermediate 

 between denticulatum and pubescens, having the texture of the form 

 a., but wider final parts. The fronds are light green, coriaceous, the 

 petioles and rachises stone-colour when dry, channelled and pubescent. 

 The barren fronds are rather larger, and the teeth are almost mucro- 

 nate. The very firm involucres are probably eventually deciduous. — 

 Endemic. 



24. N. denticulatum, Hook. — Rootstock woody, rather stout, erect — 

 decumbent, densely clothed with long dark glossy linear attenuate 

 scales; stipites caespitose, erect, 1-lJ ft. h, castaneous, subangular and 

 densely clothed at the base with falcate scales like those of the root- 

 stock, which have scars when they drop ; fronds deltoid, quadripinnate, 

 1-1 J ft. 1. and about the same w., acuminate, coriaceous and stiff, gla- 

 brous, glossy and dark green above, paler beneath ; rachis and costae 

 bright light chesnut brown, channelled, often rather flexuose ; pinnae 

 spreading, lowest pair subdeltoid, deeper on the underside, those above 

 these equilateral, 4-6 in. 1. 1J-2 in. w., lanceolate, acuminate, all petio- 

 late ; ultimate segments, ovate or oblong, 2-3 li. 1. and about half as 

 wide, cuneate at the base, the outer part cut into sharply pointed or 

 spinulose teeth ; veins pinnate in the final segments or forked ; sori co- 

 pious, terminal on the short anterior veinlet or spur ; receptacles scaly : 

 involucres dark, firm, at length deciduous. — Aspidium, Swartz. 



Common in forests at 5000-7000 ft. altitude. The species is well , 

 marked by the very abundant dark narrow scales of the rootstock and 

 stipes, its stiif texture, glossy naked surfaces, and sharp segments and 

 teeth. It varies a good deal the size of the final segments. 



Sub sp. rigidissimum. — Fronds nearly as large, less deltoid, pinnae 

 more numerous, closer and more spreading, the lowest pair, though 

 usually rather the largest, not distinctly enlarged ; ultimate segments 

 \ li. w. 1-2 li, 1. mucronate, often forked, but not otherwise toothed. — 

 N denticulatum var. rigidissimum, Hook. Poly stick urn disscctum, Fee. 



Gathered by Dr. Morris and Mr. Sherring near Blue Mt, Peak ; still 

 more rigid thim the type, of more compact habit, with, as it were, the 

 final segments of that cut between the teeth to the axis into narrow 

 separate segments, sharply mucronate, but not toothed. 



25. N. effusum, Baker. — Stipites subtufted from a strong shortly- 

 creeping scaly rootstock, 2-3 ft. L, scaly at the base, glabrous, or with 

 the channel puberulous ; fronds deltoid in outline, 2-3 ft. L and as 

 much w. chartaceous ; quite naked, vivid green and shining on the 

 upper side, tri-quadripinnatifid ; lowest pair of pinnae largest and much
