128 GYMNOGRAMMA LEPTOPHYLLA. 
their whole length is the fructification. Finally, the 
spores run together, and usually cover the whole under 
surface of the leafit. 
This has long been known as a native of the southern 
continent of Europe, its adjacent islands, and Madeira, 
but it was not until 1852 that it was found to be a 
native of the British Isles. In that year it was discovered 
by N. B. Ward, Esq., and others, in the Island of 
Jersey. It was growing on moist banks having a southern 
aspect, where Marchantia flourishes. Mr. Ward found 
it in various localities, besides near St. Aubyn's and St. 
Lawrence. It is not unlikely to be discovered at the 
back of the Isle of Wight. 
Mr. J. Reeve informs us that the Gymnogramma 
leptophylla is well worth cultivating ; and although 
considered quite hardy, will thrive best either in the 
greenhouse (which seems to suit it as well as any placej, 
stove, or Wardian case. If cultivated in the open air, 
a sheltered situation should be chosen sheltered from 
C'jld, cutting winds, as well as from the burning rays of 
the sun, both of which will prove very injurious, if not 
fatal, to its slender fronds. A warm, shady nook, in a 
rockery, will, therefore, be the best situation for it In 
this situation, a free, open compost, of equal parts leaf- 
mould and peat, with an addition of sand, will grow it 
well. It must have a moderate supply of water over- 
head during the season of growth; but such watering 
must be withheld as the autumn approaches. During 
the winter months it will require no water, but must 
have a slight protection if it remains in the rockery out-
