This species occurs in alpine or sub-alpine districts over the 
greater part of Europe, being recorded from Sweden and Norway, 
France, Belgium, Germany, and Italy. Ledebour does not mention 
its occurrence in the extensive range of country, both European and 
Asiatic, represented by the Flora Rossica. It is however found in 
India; in the Azores and Madeira, and in South Africa; im the 
island of Mauritius ; in Chili and Brazil; in New Holland, and in 
New Zealand. There also occurs in New Zealand, as well as in 
Tasmania, and New Holland, and again at the Cape of Good Hope 
and in the Organ mountains of Brazil, a variety, the H. cupressiforme 
of Labillardiére, which differs in its narrower recurved segments, 
in this respect resembling H. unilaterale, but having the denticulate 
involucre-valves of H. tunbridgense. 
The culture of this plant assimilates closely to that of Tricho- 
manes, to which we may refer. We here subjoin some very explicit 
instructions published by Mr. Johnson*:—“ It prefers being kept 
continually damp and warm, which renders it a most valuable acqui- 
sition to the Wardian case, where it may be grown separately, as 
also under a plain bell-glass, or may be mixed with others which 
likewise prefer a similar situation; but whichever may be chosen for 
its cultivation, rather more care will be necessary in arranging 16 
than will be required for most other Ferns. The situation it gene- 
rally chooses for its habitat will be found to be nearly or quite free 
` from all vegetable moulds, and these may be quite dispensed with 
in pot or artificial culture. Although we have seen it grown very 
well in equal parts peat and silver sand, yet we have always found it
