MACLOSKIE : REVISION OF FLORA PATAGONICA. I I 



stdincisa and the West Patagonian plant, I was obliged to treat the speci- 

 mens from Rio Aysen as a species. I will say, however, that it is very 

 probably more correct to regard the plant in question as a variety of D. 



subincisa. 



D. SPINULOSA (Mull.) O. K. var. DILATATA (Hoffm.) Chr. 

 Falklands ; widely spread in temperate regions ; not previously found 

 in S. America (Skottsberg). 



POLYSTICHUM Roth. Macl., p. 132, Dryopteris. 

 Frond lanceolate, coriaceous, bipinnate ; pinnae lanceolate, obtuse, 

 rough-paleaceous underneath: pinnules trapezoid mucronate, spinulose- 

 toothed, sometimes subauriculate. Spores roughish. 



P. ACULEATUM (L.) Roth var. Macl., p. 133 (sub Dryopteris]. 



Only the bare name being given by Macloskie, I may assume that it 

 refers to the typical form of this species. 



Macloskie refers to it as occurring in S. Patagonia, and Reiche in N. 

 W. Patagonia at Rio Manso and Skottsberg in the deciduous forests of 

 northwest Patagonia. Although I have seen no specimen from those 

 localities, I may be allowed to doubt whether it, really, is the typical form 

 that is meant here.
