AT 
NEPHRODIUM. Buckler Ferns. Including Pachy- 
deris, Phlebigoniwm, Podopeltis, Proferea, and Pycnopteris. 
This genus includes many species remarkable for their 
decorative qualities, and others unequalled for their 
hardiness and power of endurance. Plants of all 
dimensions are found amongst Nephrodiums, from the 
tiny-growing N. pedatwmand N. sanctum, with fronds 
only a few inches long, to the majestic N. villosum or 
the beautiful and massive N. Boryanwm, both of which 
produce very handsome fronds from 4ft. to 6ft. and even 
frequently 8ft. in length. Whatever their size, however, 
Nephrodiums are all of easy culture, a property which 
market growers have not been slow in appreciating. 
Even the commonest of all, N. molle, which for years 
was considered no better than a weed, has sprang into 
commercial popularity. When specimens of this species 
are planted out on the rockery, where all Nephrodinms 
seem to thrive, they soon become objects of great beauty ; 
but, whether grown in that way or as pot plants, they 
require a richer soil than most other Ferns. 
All the Nephrodiums thrive in a mixture of loam and 
peat, which, for the most robust kinds, should he in 
about equal proportions, with a small part of cow-manure 
previously dried and well mixed together, and an 
additional sprinkling of silver-sand; for the smaller and 
consequently slower-growing species, less loam and more 
sand should be used. 
Most Nephrodiums, especially the strong-growing kinds, 
are quite indifferent as to shading; a little sunshine acts 
as a strengthening agent, making their foliage much 
more lasting during the winter months than could other- 
wise possibly be the case. They all require a good 
supply of water at the roots all the year round, but 
principally during the growing season. Although they do 
not actually suffer from occasional waterings overhead, it 
is very doubtful if they derive any benefit therefrom: the 
foliage of many kinds, being of a soft texture, soon gets 
spotted and loses its beauty if allowed to remain in a 
wet condition for any length of time. Im any case, the 
plants must not be kept close; confinement in the case 
of Nephrodiums means not only an invasion of Thrips, 
their greatest enemy, but also that brownness of mature 
fronds which often puzzles the amateur grower. ‘The 
only way to avoid such unhealthy appearances is to grow 
the plants in well-ventilated houses, where moisture 
cannot condense on their foliage. 
Nephrodiums are easily and rapidly propagated by 
means of their spores, which are abundantly produced 
and germinate very freely; the species provided with 
creeping rhizomes may also be increased by the division 
of these organs, which operation is most successfully 
performed during the months of March and April. . 
Considered as a purely British species, the beautiful 
N. cristatwm is one of our rarest plants. Owing to its 
native places being boggy situations, it is, however, 
somewhat difficult to grow successfully for any length of 
time. As an ontdoor Fern, if planted in peaty soil near 
the water, it will flourish as well as in its native 
habitat ; but in less favonrable situations it will become 
weaker every year, until it finally, in two or three 
years, dies. ° 
N. decompositum is of comparatively easy culture, and 
is altogether a most desirable plant. It is usually of 
medium growth, exceedingly useful for table-decoration, 
and also for forming an edging in the rockery in front 
of taller kinds, as it is of a neat and compact habit. 
N. d. glabellum is well adapted for pot culture, or for 
planting in nooks in the rockery where there is but little 
soil or space at disposal. It is also a capital plant 
for Fern-cases, as generally seen in dwelling-rooms, 
where it grows luxuriantly, its tender, soft green colour 
forming a striking contrast with plants of a darker hne. 
The beauty of this variety is readily destroyed by watering 
or syringing overhead, which causes the fronds, young or 
old, to assume a brownish, sickly appearance. 
N. erythrosorum is a highly decorative species, in many 
respects distinct, and deserves to be cultivated on a large 
scale. “It has proved perfectly hardy eyen in London, 
haying stood, without any protection whatever, the 
test of our hardest winters; but under such treatment 
it becomes deciduous. When treated as a cool indoor 
subject, its magnificent fronds, of a beamtiful bronzy hue 
ina young state, but turning with age to a dark shining 
green, remain on the plant all the year round, and make
