Pres] and in Ind. Fil. therefore renamed Dr. lenuifolia. L. tenuifolia Pr. is how- 
ever a form of D. submarginalis, and therefore I must fall back to the specific 
name alsophilacea. The species is confined to the mountains of South-eastern 
Brazil, and I name here some collector-numbers.

Type from Rio, not seen, but numerous specimens from Rio agree perfectly 
with Raddi's figure, and I consider them typical. They can be described as 
follows: 
Rhizome obliquely erect. Stipes fasciculated, up to 3—4 dcm long, slender, 
brownish stramineous, very shortly hairy and like the apex of the rhizome clothed 
with black-brown, rather thick and rigid, entire and long acuminated scales, which 
are 1 mm broad and 4—5 mm long; in the upper part of the stipe the scales be- 
come fewer and deciduous. Rachis like the stem, somewhat angular and bisulcate 
above. Lamina deltoid-lanceolate with the lowest pair of pinnz not or a little 
reflexed, towards the apex rather suddenly narrowed but without a distinct, 
terminal pinna, herbaceous, generally dark-green, 30—60 cm long, 20 cm broad. 
Larger pinne shortly petiolulate, lanceolate, 10—13 cm long, 2—2'/» em broad, 
subopposite, ciliate, truncate at the base, acuminate, the basal pair often with the 
lower side enlarged. Coste above densely tomentose by crisped, pluricellular, 
reddish hairs, which in some forms also occur on the veins and leaf-tissue; costce 
beneath with some few small, entire or rarely slightly dentate, reddish-brown 
scales, which are ovate with a long hair-like apex and formed by almost isodia- 
metric cells with rather thick walls (fig. 32), surfaces glabrous or more or less 
glanduloso-pubescent. Basal segments sometimes quite free and very often much 
reduced. Larger segments a little falcate, as a rule faintly dentate, obtusely rounded 
at the apex or in some forms submucronate, 3—4 mm broad, connected by a very
