l. WkiGELA Rosea. Rosy Weigela, Hardy Shrub 
(Caprifoils) North of China. Native name “ Noak- 
chok-whoa.”” 
* A shrub like a Philadelphus ; old stems whitish, 
smooth; young ones green, slightly winged; wings 
alternating with the leaves and covered with hairs ; 
leaves. opposite, nearly sessile, elliptical, 13 inch wide, 
3 inches long, serrated above, nearly smooth below, on 
the midrib and veins hairy; flowers.axillary and termi- 
nal, three or four springing from each axil. or end o! 
the shoot, rose-colour ; peduncles short with green short 
thread-like bracts at the base ; calyx cleft into five un- 
equal segments, three above and two below, two-lipped, 
smooth, light green; corolla monopetalous, tubular ; 
mouth reflexed and cleft intofive equal segments, smooth; 
stamens five, shorter than corolla, and inserted or grow- 
ing to its sides ; smooth above, but hairy from the point 
of union to. the. base of the corolla; style 1; stigma. 
capitate, a little longer than the stamens; germen 
inferior, rather more than an inch long, nearly sessile, 
and having the appearance of part of the peduncle o 
the flower.” Such is Mr. Fortune's description of this 
most beautiful shrub, which has reached this country 
in safety, is apparently hardy, has already been distribu- 
ted by the Society to a limited extent, and promises to 
fake rank with the Chinese Azalea as an object of orna- 
ment. drawing received from him represents it as 
forming loose elusters of from three to five flowers at 
the end of every little side branch, and his dried speci- 
mens show that the drawing is faithful in that respect. 
The flowers are rather more than an inch long, and are 
an inch and a half in diameter when expanded. In 
colour they axe very like the well-known Chinese Crab 
(Pyrus spectabilis), pure white under, deep. rose exter- 
nally. The genus Weigela, which originated with the 
Swedish traveller Thunberg, has been referred by mo- 
dern botanists to Diervilla, and several species of it 
inhabiting Japan have been published by Messrs. Sie- 
bold and Zuccarini under that name. But although in 
many technical characters it approaches that genus, yet 
it is very different in habit; and since the seed-vessel 
is not i , and the seeds winged, 
not wingless, it seems expedient to preserve the original 
genus. e species now described is more like the 
Calysphyrum floridum, also a Weigela, and a most beau- 
tiful one, from the North of China, than any of the 
Diervillas of Siebold and Zucearini, from all which it 
differs in its very large flowers, except their D. grandi- 
flora, the leaves of which have very long stalks, and the 
stamens hairy filaments. Hitherto this plant has been 
kept in a greenhouse, but it has so much the appearance 
of a hardy shrub that, especially considering its flower- 
ing in the North of China in the month of April, it will 
probably live in the open air.—Journal of the Horti- 
cultural Society, p. 65. 
2. DENDROBIUM SCHŒNINUM. Fluted Dendrobium. Stove 
Epiphyte. (Orchids.) New Holland. Messrs, Lod- 
diges, 
Sp. OnAn.—Stems slender jointed, smooth, hard. Leaves, terete 
fluted. Flowers solitary, white, middle sized, Sepals and 
etals drawn to a fine point, the former a little powdered 
with violet, Lip white, edged with crimson, 3-lobed: the 
back lobes blunt and short, the middle one taper pointed, 
with 3 green wavy raised lines along the middle. Column 
with two erect, rounded, crimson-edged wings. 
A curious ‘little epiphyte, with the habit of Dendro- 
bium calamiforme,and some other New Holland species, 
and probably very near the little known. D. crispatum. 
Tt has nothing to d it to. the cultivator, except 
its singular manner of growth, which resembles that of 
a little Bamboo, but with terete fluted leaves. It is 
occasionally sent to this country, under the. erroneous 
name of D. canaliculatum.—J. L. 
3. HABROTHAMNUS corymposus.  Corymbose Habro- 
Greenhouse. shrub. — (Nightshades.) 
A very handsome species, sent to Kew by Mr. Low, 
of Clapton, quite distinct. from the H.: fasciculatus. 
It is everywhere glabrous, apparently a much taller 
plant, and with the corolla of a very different shape, 
widening upwards and then suddenly contracted, so as 
to have an urceolate tube ; and having the segments of 
the corolla much longer, acuminated, and at length 
reflexed. Its growth appears to be much more rapid, 
and it is. more easily cultivated, only requiring the pro- 
tection of a greenhouse in the winter. In summer it 
does best in the open air, and may readily be increased 
by cuttings. As far as can be judged from the descrip- 
tion, it seems to be the Meyenia corymbosa of 
Sehlechtendahl.— Botanical Magasine, 1845, t. 4201.

The Derby Florists’ Challenge.—There appeared in 
our columns, a week or two ago, a notice of a match 
likely to. take place between the florists of Derby and 
Nottingham, the former offering to show 30 distinct 
varieties of Tulips,whilst the latter considered 12 would 
be sufficient ; some correspondence has taken place 
between the parties, and as the Derby growers (who 
are the challengezs) will not lower their number to 12, 
the “men of Nottingham," have proposed to remove 
the difficulty by meeting half-way, and exhibit 2! dis- 
tinct varieties; 4 blooms in each of the feathered classe 5 
and. 3:blooms in each of the flamed, their object’ being 
quality, before quantity ; they have. likewise offered to 
select five florists of Nottingham, who shall each eut 
a pan. of six flowers from. his own en, which pans 
shall be exhibited against a similar number of the Derby 
florists for any sum not exceeding 107. Mr. Wood; of 
The. Coppice, Nottingham, has also proposed to stage a 
pan of'six distinct varieties, one in each class, against 
the best. pan that.can be produced by any Derby florist 
for. any sum. not exceeding 5/., thus bringing into.com- 
petition some. of the best flowers grown in that part of. 
the country. We understand that, should the Derby 
florists not accede to. any of the terms proposed, the. 
Nottingham growers will leave: the preliminaries to be 
settled by any indifferent person or persons, and exhibit 
according to their arrangements. 
The means employed for obtaining Double Flowers.— 
How many erroneous circumstances up to this: da 
have been admitted to explain the cause of doubleness. 
in certain flowers! us, for example, many gar- 
deners pretend, that, to obtain double Brompton Stocks, 
you must gather the seeds exclusively from those 
flowers which are the most double. What influence can 
these flowers have when entirely deprived of all the 
organs of generation? None whatever. To. explain 
this phenomenon, we must make practice agree with 
theory. Every gardener who sows seed, wishes to ob- 
tains plants with double. flowers, so as to obtain blos- 
soms which produce the. greatest effect. Every double 
plant is [a monstrous vegetable. To [produce this ano- 
maly, we must attack the principle of its ereation, that 
isto say, the seed. This being granted, let us examine 
in what way these seeds ought to be treated, If, after 
having gathered the seeds of Maleolmia annua, or 
Ten-weeks Stock, we sow them immediately afterwards, 
the greatest number of the seedlings will produce single 
flowers, whilst, on the contrary, if we preserve these 
same seeds for three or four years, and then sow them, 
we shall find double, flowers upon nearly all the plants. 
To explain this phenomenon, we say that in keeping a 
seed for several years, we fatigue it and weaken it. 
Then, when we place it in a suitable soil, we change its 
natural state, and from a wild plant make it a culti- 
vated one. What proves our position is, that plants, 
in their wild state, shedding their seeds naturally, and 
sowing them as soon as they fall to the ground, yet ina 
long succession of time scarcely ever produce plants 
with double flowers. We. think, then, after what we 
have said, that whenever a gardener wishes to obtain 
double. flowers, he ought. not to sow the seeds till after 
having kept them for as long a time as possible.—This 
practice ought to be observed with all plants that we 
wish should produce double flowers, for all varieties of 
the Brompton Stocks, Pinks, &. As to Brompton 
Stocks, Ten-weeks Stocks, and others of the same kind, 
there. is no doubt that to flower them well they should 
be sown in autumn in well-worked soil, taken up when 
the cold weather comes, and kept under a frame during 
the winter. In the spring they may be planted out 
again, when they will flower. magnificently, and yield an 
abundant harvest of seeds. If you have not a frame 
at your disposal, you may obtain the same result by 
sowing the seeds, at the end of February, under a south 
wall, for example.. The principles that we admitted 
above, are just as applicable to Melons and all plants of 
that family. e admit, like many other observers, 
that Melon plants obtained from seeds the preceding 
year, ought to produce, and do produce, really very 
vigorous shoots with much foliage ; but very few fruitful 
flowers appear on such plants, whilst, on the other 
hand, when we sow old seeds, we obtain an abundance 
of very large fruit, In fact, in all varieties of the 
Melon the seeds should always be kept from three to 
eight years before being sown, if we would obtain fine 
fruit and plenty of it.—Revue Horticole. 
CALEN. OF OPERATIONS. 
(For the ensuing Week.) _ 
Tre usual mode of inducing shy blooming plants to 
produce flowers is to cramp their roots. We have ro 
such” control, however, over Orchids, for if we confine 
their roots, we disarrange their economy, and endanger 
the existence of the more delicate kinds ; but as most of 
them will exist in a dormant state for many months, if 
moisture is withheld from their roots, we can compel 
them to alter their natural time of growth to suit our 
seasons. Spring and autumn growth should, therefore, 
be discouraged by these means, with all the shy bloom- 
ing kinds. e experi ow by 
keeping them as cool and dry as they can bear for about 
six weeks, and in spring, by increasing the heat as the 
season advances, but still withholding water till early in 
the summer, and then giving it only when their buds are 
ready to start. In reference to the shy blooming kinds 
the most essential part of their management is to com- 
pel them to confine their growing season to our sum- 
mers—say from the middle of May till the end of Au- 
ust. Young Stanhopeas are more difficult to flower 
than established plants ; because they are more sus- 
ceptible of being influenced by changes of temperature 
ormoisture. At this stage they may be made to grow 
in any month in the year. ‘They will also endure more 
hardship than any other of the tribe. From this time 
to the beginning of May give as little water at the roots 
as is consistent with the health of the plants, and to the 
middle of February, 55°is the proper temperature. The 
atmosphere should not be drier than that for a collec- 
tion of stove plants; therefore, where two houses do 
not exist, the coldest end of a stove is a gopd place to 
winter them in.
