ASPLENIUM L. 



A. TRILOBUM Cav. 



(Syn. Asplenium trapezoides Sw.) 



Folia glaberrima, ad i dm. usque alta, plerumque tamen breviora ; stipes 

 saepe fronde 2-3-plo longior, apicem versus compressus, dilatatus ; frons 

 triangulari-rhomboidea vel rhomboidea, coriacea, plus minus decurrens, 

 integra vel subtrilobata, ad 4 cm. usque longa et 2.5 cm. lata, marginibus 

 basi integerrima excepta crenulato-dentatis ; sori oblique dispositi, crassi, 

 ovali-lineares ; indusium latiusculum; spori oblongi, ferruginei submar- 

 ginati. 



W. Patagonia, its northern section in the evergreen forest. 



Description. Leaves glabrous, usually shorter than i dm. ; stipe gen- 

 erally two or three times longer than the frond, compressed above ; frond 

 coriaceous, rhomboid to subtriangular, decurrent, undivided or subtrilobate 

 with margins entire at the basal part, crenate-dentate at the middle and 

 upper part of the frond ; sori crass, with oblique position. 



Asplenium magellanicum Kaulf. occurs also in North Patagonia by 

 Lago Nahuel-huapi ; W. Patagonia, on both sides of the Cordillera. 



A. multifidum Brack., Macl., p. 132, must be deleted. It is not found in 

 our district. Besides A. multifidum is synonymous with A. shuttleworth- 

 ianum Kee ; the last name should be adopted, being older than former. 

 It belongs to the flora of Polynesia. D.

 versus subcomplanatus ; frons oblonge vel elongate triangularis, obtusa, 

 coriacea, in parte superiore pinnata, in parte inferiore bipinnatifida, pinnis 

 segmentisque obovato-cuneatis illis vix incisis, his inciso-dentatis ; sori
