dark and thick, the lumina small; those of the costæ beneath adpressed, not paient 

 (fig. 3,5); 4) stipe at the base with some dark-brown, rather long scales. — Sori 

 small, medial, exindusiate. — From D. alsophilacea, to which 

 it is closely related, it differs by its more numerous and close 

 pinnæ, its larger scales and by the short, pinnatifid apex of 

 the lamina. 



D. pedicellata is confined to Southern Brazil, where it 

 seems to be a rather common species, I have seen the follow- 

 ing additional specimens (for others see Rosenstock Hedwigia 

 4«: 117).

A very distinct species, in cutting very near D. pedicellata, 

 in size, colour and scales near D. eriocaulis. Stipe below with 

 a dense mass of long, reddish scales. Lamina yellowish-green, 

 firmly herbaceous or membranous, 50 — 60 cm long; pinnæ 

 about 20 cm long by 4 cm broad, acuminate, incised about 

 halfway to the costa into 7 mm broad, bluntly rounded or 

 subacute, faintly toothed or entire segments. Rachis and costæ 

 beneath scaly by red, narrow, entire scales with thin cell-walls, 

 much like those of D. eriocaulis but their base flat; scales of 

 costæ patent, mostly at right angles to the costa (fig. 3,6). Mar- 

 gins and veins beneath finely pubescent, the underside some- 

 times glandular by red, sessile glands. Veins 9— 11-jugate, the 

 lower 3 — 5 running to the sinus, the lowermost much ascend- 

 ing, the upper ones not reaching the margin. Sori medial or 

 slightly inframedial, exindusiate. 



Judging from the structure of the scales this very beau- 

 tiful species is more related to Ü. eriocaulis than to D. pedicellata, and stands 

 to that species as Ü. pedicellata to D. ctenitis.
