The present is perhaps the most frequent of the five species that are now enumerated of this sin- 
gular genus. It exists in the collections of almost all the travellers who visit the islands of the 
Pacific, situated within the tropics: it has existed in the rich herbarium of our invaluable friend 
Mr. Menzies ever since the year 1792, when he gathered it in Otaheite during the voyage of Cap- 
tain Vancouver; and it has by him been distributed among other botanists: but it appears to be 
particularly abundant in the Sandwich island group, north of the equator. The habit of this 
genus is so unlike that of .Polypodium, to which it would, upon a slight inspection of the sori, be 
referred, that Gaudichaud has done wisely in constituting it a new genus. Its habit is quite peculiar, 
though it must be confessed that the generic marks are not very decisive. The irregularly 2-lobed 
receptacle of the capsules we do not distinguish. 'To us the sorus seems to spring from one common 
point at the extremity of the nerve or midrib.
