character it approaches D. pubescens. —- N. popayanense is nearly typical; its scales 
are slightly toothed and the indusia glabrous.

A comparison of the two original specimens (from Herb. Mett. and Herb. Hook.) 
of the two species adopted by Baker in Syn. Fil. shows at once, that they belong 
to the same species; as to texture, colour, cutting, shape of pinnules and most other 
important characters they agree perfectly; the only difference found is in pubescence, 
D. Triane having the secondary rachises very shortly puberulous by articulated 
hairs, while D. firmifolia is perfectly glabrous. 
Rhizome not seen. Stipe about 50 cm long, fuscous, glossy, three-channelled 
above, with some few entire, narrow, lanceolate scales below, upwards without 
scales and hairs. Lamina broadly lanceolate, 60—-70 cm long, about 40 cm broad 
below the middle, firmly chartaceous or subcoriaceous, pale-green beneath, totally 
glabrous, or, as in the type-specimen finely and shortly, deciduously (?) puberulous 
on the secondary rachises, tripinnatifid in the lower half, bipinnate at the middle. 
Pinne alternate, at distances of 8—10 cm, stalked, those of the 3rd or 4th pairs from 
below the largest, about 20 cm long; basal pinne broadest below the middle, nar- 
rowed towards both ends; upper pinnz somewhat unequal at base, the lower side 
being the narrower. Pinnulz at distances of 2—3 cm, the lower ones short-petiolate, 
the middle ones sessile, the upper decurrent, all acute at apex, cuneate at the 
posterior base truncate but not auricled at the anterior one, 3—5 cm long, 1—1'/2 
em broad, larger ones (those of the lower 3 or 4 pairs of pinnz) lobed halfway 
down to the midrib, the lobes obliquely rounded, sometimes emarginate at the apex, 
the edges repand or broadly and shallowly crenate, towards the apex subacutely — 
serrated, Pinnulze of middle and upper pinne with repand or crenated edges. Veins
