united it, and to D. nemophila, but the whole aspect of the plant is rather different 
from both, and it seems to be well-marked by its scales. The basal scales are of 
the same reddish-brown colour as those of D. nemophila; rachis, midribs of pinnz 
and pinnule beneath are, especially at the axils, densely covered with appressed, 
antrorse, broadly lanceolate dirty- or blackish brown, glossy scales, which consist 
of numerous, small cells and are toothed or shortly fimbriate throughout along the 
margins. Both surfaces densely glandulose throughout with glossy, glandular hairs. — 
Pinne ovate-oblong-acuminate, 25 cm long, curved upwards; secondary pinnule 
oblong-acuminate, tertiary ones fully free at base at the lower half of the secondary 
pinnulz, sessile or adnate, 7—8 cm long, 2 cm broad, somewhat falcate, bluntly 
obtuse, incised more than halfway down into about 6—8 pairs of falcate, truncate 
quaternary segments..Indusia rather persistent, reddish, glanduloso-ciliate. Texture 
herbaceous, colour dark-green. For other details see Hooker’s description. 
In cutting it resembles D. ampla, still the pinne are ovate-elongate, not lan- 
ceolate, and upcurved; the obtuse tertiary pinnule resemble those of D. nemophila.

A large species related to D. ampla but very distinct. Base of stipe with a large 
tuft of linear, silky, beautiful scales that are of a deeper reddish-brown colour than 
those of D. ampla. Stipe 2 em thick, 1—1'/2 m long or more, deeply furrowed above, 
clothed with numerous, lanceolate, reddish brown, appressed and antrorse scales. 
Lamina up to 2 m, perhaps 3 m high, membranous, dried of a reddish-brown 
colour, pinnatifid. Basal pinnz the largest subopposite, 1 m or more long, with the 
basiscopic pinnules of the lower third produced, from the third or fourth pair of 
pinnules equalsided. Medial pinnz 50 cm or more long, acuminate, stalked, often 
falcate. Secondary pinnules at distances of 3—5 cm, the lower ones short-stalked, 
most of them sessile, the upper ones adnate and shortly decurrent, somewhat falcate, 
shortly acuminate, incised below to costa. Tertiary segments oblong, up to 2 cm 
long, 5—7 mm broad, nearly of the same width from base to tip, abruptly decurrent - 
at base the apex obtuse or bluntly rounded, toothed, the margins incised halfway 
down into about 10 close, falcate, truncate lobes on each side. Rachis and midribs 
of pinnze and pinnules beneath rather densely fibrillose with lanceolate-acuminate, 
reddish-brown, antrorse scales, midribs of tertiary segments beneath with similar
