 near Moro Velho, n. 5334, and Serra do Frio, n. 5332, Gardner. S. Brazil, 

 Sellow. — This species is extremely well figured by Humboldt in the work 

 above quoted, and is indeed a very remarkable one, with a habit in many 

 respects considerably different from that of other A/sophilce. The piniige 

 and pinnules do not spread at almost right angles from the rachis, which is 

 common in the present genus, but point upwards. It is more divided, so 

 as to be at least tripinnate. The whole plant, too, especially in a young 

 state, is clothed with lax, deciduous, cobwebby hairs. 



21. A. plagiopleris, Mart. ; " fronds bipinnato-partite, sti- 

 ])es aculeate, partial rachis and veins downy above, scales on 

 the veins kw and deciduous, pinnae linear-oblong acuminate, 

 pinnules linear much acuminated and pinnatilid, segments 

 between the rather broad sinuses lanceolate falcate toothed at 

 the apex, the fertile ones nearly entire, the sterile serrated, in 

 each pinntde the lowest and shorter segment is obliquely ad- 

 nate with the rachis, sori upon the entire segments from 8 — -

 My own specimen of this, from the Royal Berlin Herbarium, quite coin- 

 cides with the figure and description of Martins. 



22. A. paleolata, Marl.; " frond bipinnato-partite, on both 

 sides but especially beneath pubescent, the veins and vein- 

 lets beneath densely clothed with ovate white scales, stipes 

 and rachis actdeate, common and partial rachis and veins 

 strigillose above, pinnae linear-oblong shortly acuminated, 

 pinnules linear shortly acimiinated pinnatifid, the apex ser- 

 rated, the segments linear-oblong subfalcate toothed in the 

 upper margin, the ultimate ones confluent so as to form ser- 

 rated pinnae sori in the lower part of the segments 4 — 8

 here, or to the preceding very dilTerent species : and Knnze quotes both 

 of these under his Aluop/iila vil/nsa.
