Presl and in Ind. Fil. therefore renamed /);•. tenuifolia. L. teniiifolia Pr. is how- 

 ever a form of D. submarginalis, and therefore I must fall hack to the specific 

 name alsophilacea. The species is confined to the mountains of South-eastern 

 Hrazil, and I name here some coUector-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 dem 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 — ö 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 pinnæ 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 pinnæ shortly petiolulate, lanceolate, 10 — 13 cm long, 2— 2'/-3 cm broad, 

 subopposite, ciliate, truncate at the base, acuminate, the basal pair often with the 

 lower side enlarged. Costæ above densely tomentose by crisped, pluricellular, 

 reddish hairs, which in some forms also occur on the veins and leaf-tissue; costæ 

 beneath with some few small, entire or rarely slightly dentate, reddish-brown 

 scales, which are ovate with a long haii--like apex and formed by almost isodia- 

 metric cells with rather thick walls (fig. S"), 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 submucronale, 3 — 4 mm broad, connected by a very
