Fee's plate cited above is a good figure of 

 this species, which is intermediate between D. 

 pedicellata and D. falciculala var. paranaensis; it 

 is marked by its remote and long-stalked pinnæ, 

 its distinct terminal pinna and its few and small 

 scales. Pinnæ in 6 — 7 pairs, at distances of 

 5—6 cm, shortly acuminate, incised "/:■. of the 

 way to the costa into falcate, entire, obtuse seg- 

 ments; scales of the costæ beneath very few and 

 small, narrow-linear, scarcely toothed, dark-co- 

 loured, (fig. 3,1(1). Surfaces glabrous; colour dark- 

 green; texture membranous. Veins 8— 10-jugate, 

 the lower 2 running to the sinus. Sori medial 

 with a subpersisteni, reddish, glabrous indusium. 

 Rhizome oblicpie with numerous retlbrown scales 

 at the top, but not with a dense mass of long 

 scales. 



A very constant species, which I had iden- 

 tilit'd (following Mettenius) with Lastrea leimifolia
