BOTRYCHIUM LUNARIA (THE MOONWORT). 
THIS ranks, with the Adder’s-tongue, amongst the lowly forms 
of oar British Ferns, having, like that, only one frond, with a 
fertile spike in the centre. The frond, however, is once divided, 
and the fertile spike is a'so divided, so that it is easily distinguished. 
It grows in dry mountain pastures, but is very inconspicuous 
and difficult to cultivate. It has also furnished no notable 
varieties, and hence is mentioned here merely by way of 
completing the list of native species, since, though pretty in its 
way, it cannot be considered of any decorative value, nor does 
it lend itself to culture. 
CYSTOPTERIS (THE BLADDER FERNS). 
THE Bladder Ferns, though pretty enough in their native 
habitats, viz., chinks in rocks and stone dykes, besides a lack 
of definite variety, have a terrible knack of becoming brown 
and almost black under cultivation ; their fragility, too, is against 
them as decorative Ferns, and hence we mainly allude to them 
as evidence that they have not been forgotten. Three species 
are imputed to Great Britain — C. fragiiis. C. alpina, and 
C. montana, the last of which resembles P. dryopteris in form 
of frond and cutting, and is decidedly the prettiest of all. We 
l ave had it growing rampantly in a slate trough, well drained and 
filled with rough peaty and loamy compost. The tribe obtains 
its botanical and popular name, which is an exact translation, 
from the fact that the indusia or spore covers are thin and 
globular, resembling tiny bladders. All have creeping roots, 
and form clumps which, subject to the disadvantage aforesaid 
of discoloration, are pretty enough in rocky chinks under glass 
or in the open. C. fragiiis is the only one which has sported, 
the only two really marked forms are C. f. var. cristata, 
raised and found wild subsequently, in which the fronds vary 
from almost normal, through prettily crested .-types up to 
grandiceps, with quite small pinn^, and C. f. var. Dickeana, a 
dense-fronded dwarf form, very pretty, which has been found 
in several places. C. f. crispa resembles this, but is crispier.
