CHRISTENSEN, ON SOME SPECIES OF FERNS. 5 
Patagonia austr.-occ: Skyring, P:to Pangue, 29. 4. 1908, 
Falkland Islands: Saunders Island, 15. 12. 1909. 
This species was not found before so far south as the 
Skyring Water and is also new for the Falkland Islands. It 
differs constantly from A. aethiopicum L. by its venation, the 
veins running to the sinuses between the teeth of the margin. 
Arthropteris altescandens (Corra) J. Sm. 
Juan Fernandez: Masatierra, forest by El Yunque, 
nr. 411, 24. 8. 1908 (fertile specimens); Masafuera: Quebrada 
de las Casas, 28. 8. 1908 (sterile specimens). 
Hitherto only known from Masatierra. 
Asplenium stellatum Cotta, Mem. Acad. Torino 39: 41

Syn. A. Fernandezianum Kze. Anal. pterid. 22. 1837; A. 
lunulatum Johow, Helechos Juan Fernandez 32 et auctt. 
Juan Fernandez: Masafuera, in Quebrada de las Casas 
nr. 464. The leaves collected are not proliferous at the 
apex, otherwise they agree very well with Corra' figure; 
the species is a member of the long series of forms, which 
in my Index are referred to the all-comprising A. lunulatum 
Sw. It is a near ally of A. pteropus Klf., but I consider it 
specifically distinct. Besides the prolification it is marked 
by its throughout winged stem, the wing being broadest 
below, narrower upwards; the rachis is only slightly 
winged, and the pinnz deeply lobed, the lobes again cleft. 
Cystopteris fragilis (L.) BERNH. 
This cosmopolitan species is quite as rich in form in 
temperate South America as in Europe. The most specimens 
examined belong to the subspecies fragilis Milde, Fil. Eur. 
147, thus the specimens from the Falkland Islands: Roy
