Hab. Huaylluay, near Pasco. 



The plant figured and described in the Reliquiae Haenk- 

 ianae is from the mountains of Peru. The description suffi- 

 ciently accords with our plant, and the representation of 

 its pinna Q.tf. b : but the pinnae and pinnules in the figure of 

 the natural size are not so compact as in these specimens; and 

 the Fern itself, belonging to the same tribe as our Nephr. 

 aculeatum and lohatum, is equally difficult to characterise. 



8. Cisto^iev'xs fumarioides ; frondibus ovato-oblongis flaccidis 



glaberrimis bipinnatis, pinnulis petiolatis ovatis obtusis 

 (acutisve) pinnatifidis, laciniis cuneato-oblongis obova- 

 tisque apice bi-tridentatis, rachibus alatis, soro in quala- 

 bet lacinia solitario subrotundo. Presl^ in Reliq. H(enk.

Of the two specimens I possess of this plant, one has the 

 pinnules obtuse, as described by Presl; the other acute. Both 

 are so similar to the Cistopteris fragilis of our country, that 

 I scarcely know how they can be distinguished from it. 



9. Asplenium triphyllum; frondibus linearibus bipinnatis, pin- 



nulis ternatis cuneatis apice bidentatis, media petiolata, 

 soris subsolitariis, rachi discolore. Presl, in Reliq. Hcenk.
