POLYPODIACE^. 1'65 



The palege on the stipe and rhachis are rather fugacious, and may 

 not have been present on the single specimen examined by Kaulfuss, 

 as neither he nor the authors of the Botany of Beechey's Voyage have 

 noticed them.

Asplenium Magellanicum, Kaulf. Ehum. Fil. p; 175; Spreng. Syst. Veg. 4, p.. 885. 

 Hook. & Grev. Ic. Fil. t. 180. 



Hab. Tierra del Fuego : in thickets of bushes, in the vicinity of 

 Orange Harbour. 



Plant csespitose, usually about a span high, the rootlets densely 

 coated with a rufous tomentum. Fronds deltoid-ovate, slightly acu- 

 minate, either twice or thrice pinnate, smooth, and succulent when 

 recent. Pinnules bi-trilobate ; the lobes obovate, entire, emarginate, 

 or denticulate. Indusium semiorbicular, membranaceous.

Hab. Hawaii, Sandwich Islands ; on Mouna Loa and Mouna Kea, 

 at an altitude of from 8,000 to 10,000 feet ; growing among decom- 

 posed lava. 



We are convinced, from the note of Gaudichaud, in the Botany of 

 Freycinet's Voyage, under A. patens, and the synonyme adduced, that 

 his plant was really the A. Adiantum-nigrum of Linnaeus, the same as 

 that now under consideration, a very distinct species indeed from the 

 A. patens of Kaulfuss ; which has fronds of a much larger size, more 

 lax and open in their divisions, of a membranaceous texture, and 

 with only one or two, seldom three sori on each lobe. The European 

 and Sandwich Island specimens of A. Adiantum-nigrum do not essen- 

 tially differ from each other.
