Lamina 4—7 dem long; pinne rather distant, 10—12 cm long, 2—2!/» cm 
broad; segments oblique or often subfalcate, faintly toothed in the outer half and 
generally with a mucronate apex. Veins 10—23. Sori supramedial, very often 
confined to the outer half of the segment (D. soriloba Christ). Rachis and cost 
more or less scaly; scales of coste ovate wiih a long, hair-like point, clear and 
thin, their cells large with thin walls, the edges faintly and distantly toothed (fig. 3142). 
This form comes near to D. deflexa in size, habit and colour of scales but is 
different by the subentire scales. It is confined to the Southern Brazilian States 
and the neighbour-republics; agreeing best with the original description and figure 
are the specimens from Rio Grande do Sul and Misiones; some of the specimens 
from Parana and Sta. Catharina are intermediate between this and the following 
form. — D. Sellowii Hieron. is exactly this form.

Larger than the preceding form, leaf one meter or more long, pinn: 20 cm 
long by 3—3'/» em broad, often contiguous and erect, so that the leaf becomes a 
very compact habit. Segments slightly oblique or patent, seldom subfalcate, gene- 
rally bluntly rounded at the apex and faintly toothed, sometimes mucronate. 
Scales as a rule fewer than in the typical form, those of the costa beneath 
generally hair-like consisting of a few rows of cells (fig. 34»). — Veins 12—15- 
jugate. Sori often medial, exindusiate (always ’). 
This is the common form of the mountains of the states Rio de Janeiro and 
Minas Geraes, where it was collected by almost all collectors. The original 
specimen of Lastrea tenuifolia Pres] was collected near Rio by Pout (Herb. PnEsr!);
