Although in many particulars this agrees with the Lomaria decomposita of Don, yet I am in- 

 clined to think that, were it the same, so close an observer could not have failed to have remarked 

 and described the singular and very beautiful colour of the whole underside of the frond ; on which 

 account Dr. Wallich, so long ago as 1816, when he gathered the plant in its native soil, named it 

 Lomaria aurea. It is an extremely beautiful species, and no less remarkable in the striking con- 

 trast of colour which it exhibits, than in the much divided pinnae. The first aspect of the fruc- 

 tification might have indeed well led Dr. Wallich to consider it as belonging to the genus Lomaria : 

 but if the capsules be carefully traced to their insertion, they will be found to be placed in the sinus 





itself of the
