The pre sent is perhaps the m o st frequent o f the five species that are now enumerated o f this singular
genus. I t ex ists in the collec tions o f almost all the travellers who visit the islands o f the
Pacific, situated within the tropics : it has existed in th e rich herbarium o f our invaluable friend
Mr. Men zies ever since th e year 1792, when h e gathered it in Otahcitc during the v o yage o f Captain
V an cou v e r; and it has by him been distributed am on g other botanists : but it appears to be
particularly abundant in the Sandwich island group, north o f the equator. T h e h abit o f this
genus is so unlike that o f Polypodium, to which it would, upon a sligh t inspection o f the sori be
referred, that Gaudicliaud has done w ise ly in con stitu tin g it a new genus. Its habit is quite peculiar,
th ou gh it must be confessed that the g eneric marks are n o t very decisive. T he irregularly 2-Iobcd
r eceptacle o f the capsules wc do n o t distinguish. To us the sorus seems to spring from one common
p oint at the extremity o f the nerve or midrib.
