ON CENTRE SHEET (pages 712 and 713). 
The Thalictrum leaved Fumitory (Cory dalis 
Thalictrifolia). 
Those who grow the ordinary yellow Fumi¬ 
tory will find a very distinctly marked plant 
in the above for the sake of variety. The in¬ 
dividual flowers are larger and produced in 
racemes of considerable ’length according to 
the vigour of the plants. The leaves are also 
very strongly marked, inasmuch as the divi¬ 
sions are very much broader than those of the 
common yellow Fumitory. 
The chief value of the species under notice 
lies in the fact that it may be had in flower 
nearly all the year round. If planted in the 
open air like a bedding plant, it will flower 
all the summer, and if lifted and potted 
during the present month it will continue 
flowering in potsi Those who like a, winter 
supply of flowers for the greenhouse or con¬ 
servatory would do better to keep some of the 
seedlings and grow them in pots instead of 
planting them out. By giving a fresh shift 
when required, the plants will keep on grow¬ 
ing, and in winter will bloom freely if they 
are kept in a temperature like that of a con¬ 
servatory for the keeping of ordinary green¬ 
house flowering plants in winter. 
Nephrolepis Piersoni. 
When once a fern begins to sport there is 
no prophesying when it will leave off doing 
so. A whole race of garden Ferns is now in 
existence which originated from the old 
Nephrolepis ©xaltata, well known in gardens 
for many years past. This first gave rise to 
a variety known as the Boston Fern (N. bos- 
toniensis). After enjoying a run of popu¬ 
larity for some years, the Boston Fern com¬ 
menced to sport, and one of the most remark¬ 
able of the early forms from this was N. 
Piersoni, which seems to have originated at 
Tarrytown on Hudson, U.S.A. Very soon 
afterwards, however, it found its way to this 
country, and our photograph was taken at 
Regent’s Park, where some fine specimens 
were shown by Messrs. Hugh Low and Co., 
Bush Hill Park, Enfield. 
The essential features of N. Piersoni are 
that the pinnae are very deeply cut on the 
outer two-thirds of their length, the basal 
third remaining narrow like a handle to this 
peculiar development of the frond. Some¬ 
times, however, this Fern, or rather the 
frond of it, will sport back again to the 
original N. bostoniensis, as shown by the 
tips of two fronds to the right of our picture. 
Table Decorations of Sweet Sultan. 
At the bottom of the right hand page is a 
reproduction of a photograph of some very 
tasteful table decorations set up by Miss 
Sparrow, Rookwoods, Sible Hedingham, 
Essex, on the 27th July last. The principal 
feature of the decorations consists of the pale 
mauve and white Sweet Sultan (Centaurea 
mosehata), which are lovely annuals for 
ordinary garden decoration, but which may 
also be used for floral decorations in the cut 
state to very excellent purpose when the 
manipulator is gifted with skill and taste in 
setting them up. It will be seen that only 
a limited number of these flower heads are 
used and that no violent contrast in colour 
has been permitted. The accessory flowers 
used appear to have been Gypsophila and 
Asparagus plumosus for greenery. Those 
who undertake table decorations with such 
heavy heads of flowers as Sweet Sultan are 
very liable to overdo it, but Miss Sparrow 
has exercised ample caution in the use of a 
few heads only, so that no obstructions of the 
view may be caused between people sitting 
on different sides of the table. 
Lilium Japonicum Colchesteri. 
About the middle of July a fine lot of the 
above Lily flowered in the American garden 
at Ivew. The plants were only about 18in. to 
2 ft. high and were used as an edging to a bed 
of Rhododendrons and Lilium Hansoni. The 
tubular flowers are 6 in. long, 65 m. across, 
deliciously scented, and of great substance. 
They were white inside, with greenish-yellow 
ribs on the lower half. The outer segments 
were also more or less suffused with a deep 
purple on the back, while the three inner 
ones were?only so coloured on the mid-rib. 
The stems were well furnished with 50 to 65 
scattered oblanceolate, five to seven ribbed, 
smooth leaves, each about 2in. to 4jin. long. 
There is a .'great, discrepancy as to what this 
Lily should be named, and we believe it is 
the same one which was named L. odorurn by 
Planchcn. It was also named L. japonicum 
Colchesterii in the Flores dcs Serves, tt. 2193- 
2194. More recently, we have seen it named 
L. Brownii Colchesteri. The blooms are said 
to be of a pale yellow when they first open, 
changing to creamy-white as they become 
fully expanded. As far as we have seen, the 
greenish-yellow colour of the inside is con¬ 
fined to the lower half of the flower. In any 
case, it is a handsome Lily of large size and 
deliciously fragrant. 
Until we solve the riddle of what was the 
original L. japonicum, we may be excused for 
placing this variety under that species. At 
the present day we regard what is known as 
L. Krameri as the typical L. japonicum, be¬ 
cause the flowers are more or less tinted with 
purple as originally described by Tlnmberg. 
The Giant Cow Parsnip (Heracleum 
Villosum), 
The giant Cow Parsnip is best known 
amongst gardeners under the name of H. 
giganteum, in allusion to the great size of the 
plant. Well grown specimens attain to a 
height of 10ft. to 14ft. Its beauty depends 
upon the size of the plant, because, the larger 
it grows, the more sub-tropical an appearance 
it assumes. For this reason cultivators 
should treat their plants in such a way as 
to develop them to the largest size. The plant 
is only biennial and should be sown in spring 
in a cold frame or greenhouse with the object 
of getting plants of good size to put out at 
the end of May. The ground should be deeply 
dug or trenched and manured in preparation 
for putting out the plants in May. 
During the first season the seedlings will 
only make leaves, but the larger the size 
attained by these leaves during the first 
season, the taller the plant will grow when 
it throws up its flower stem during the second 
year. The leaves should really be at their 
best during the first year, because the plant 
devotes its energy chiefly to the raising of a 
tall blanching flower stem. The flowers are 
white, like more of the Cow Parsnips, and 
present nothing very striking, but the plant 
as a whole is very effective when seen at a 
little^ distance if grown to the size of which it 
is capable. It may be used in the wild war¬ 
den or sub-tropical garden. 
Sidalcea Listeri. 
hatever was the origin of this border 
plant, it is,, no doubt, a variety of S. malvae- 
flora and may have arisen as a seedling 
variation. The distinguishing feature of the 
variety is the fringed character of the flowers, 
each petal being more or less deeply cut at 
the margin, after the style of a wild Carna¬ 
tion or Park. The photograph, being so much 
reduced by comparison with the size of the 
plant, does not show these fringes at all 
clearly. The flowers themselves are rosy- 
purple and of good size for a Sidalcea. The 
leaves are very deeply cut into three, five, or 
seven finger-like lobes and serve to mve the 
plant a graceful appearance when seen »row 
mg m the border. Our photograph was 
taken after the plant had been in flower for 
some weeks, and the lower flowers dropped 
this shows that the plant can keep up a suc¬ 
cession of blooms for some considerable time 
and still appear highly ornamental. 
1 matter of cultivation it presents 
no difhcidty, provided it is planted in any 
weli-dramed, good garden soil. If the soil 
is fairly deep and moist in summer, the stems 
will simply be taller and more vigorous than 
tney othenvise would be. The propagation 
Amy be effected by seeds and by division 
I robably it would not come true from seeds 
but a sufficient number of plants can always 
be obtained by taking off young side crowns 
with roots attached, or by lifting the whole 
plant and carefully cutting away every crown 
with roots attached and planting them imme¬ 
diately. I his operation could be done in Sep¬ 
tember more particularly after rain, so that 
the soil is sufficiently moist to give the roots 
encouragement to take hold of the fresh soil. 
I lie young plants will be established before 
winter and make nice specimens for next 
year. Large clumps of this plant would be 
fully as effective as small plants scattered 
about the oorder. 
The Large Flowered Stapelia (Stapelia 
Grandiflora). 
We here reproduce a very fine plant of the 
above-named species, grown by Mr. H Rab- 
john ganlencr to . 1 . A. Chaband, Esq.. Port 
Elizabeth South Africa. Readers will 
obseive the three-angled fleshv stems of this 
plant with numerous unopened buds and one 
expanded flower m the centre. There are 
somet ling like sixty or more species, all con 
fined to South Africa, and many of them linn 
been introduced to this country, where tliei 
aie grown either in botanic gardens or by 
pin a© glowers who feel more or less deeply 
interested 111 them. We have recently re¬ 
ceived flowers to name which were grown by 
a o' ei of this class of plants, who seemed 
very tond of them, and, judging from the 
amount of interest being taken in them re¬ 
cently, we fancy that a reaction is setting in 
in favour of this class of flowers. 
I he species under notice sent by cur 
correspondent has large flattened flowers of a 
dark purple at the base and lighter purple up¬ 
wards, striped transversely with white lines.
