named, but a better character for recognising it is 
the coarse fringe of hairs on the margin of the 
leaves. The latter are short, elliptic, generally 
smooth except for the fringe of hairs, and dotted 
with scales underneath. The calyx teeth are larger 
than those of any of the foregoing, and are coarsely 
hairy. The species accompanies R. ferrugineum in 
its native habitats, and ascends to the same elevations. 
It is an old inhabitant of British gardens, having 
been introduced in 1656. The flowers are pale 
purple varying to deep red, and are produced in 
umbellate corymbs terminating the twiggy shoots. 
The bush grows from one foot to two feet high. 
Ahother species, having a close affinity with all of 
the above, is the Myrtle-leaved Rhododendron (R. 
myrtifolium). The leaves are small, oblanceolate, 
leathery, and of a rich, dark, shining green, thickly 
clothing the branches, and the whole plant forms a 
dwarf habited bush. The under-surface of the 
leaves is densely covered with small, rusty, confluent 
scales as in R. ferrugineum. The much smaller and 
differently-shaped leaves will, however, readily serve 
to distinguish it. The flowers are larger than 
those of either of the three species already given, 
with much broader segments to the corolla. The 
calyx consists of five narrowly triangular, smooth 
teeth which will serve to distinguish the species 
botanically. 
The Ground-Cistus Rhododendron (R. Chamae- 
cistus) must not be omitted from the list, for it forms 
a very pretty evergreen, miniature shrub about six 
inches high, more resembling a Helianthemum than 
a Rhododendron. It is now named Rhodothamnus 
Chamaecistus by botanists, but is nevertheless closely 
allied to Rhododendron, and forms a little bush 
about six inches high, bearing rose flowers singly 
from the terminal bud of the shoots. Each bloom 
is about one inch in diameter, and expands in May. 
The other kinds flower from May to July. The 
Ground-Cistus likes a peaty soil, and is well adapted 
for the rock garden.— Taxus. 
THE WEIGELIA8. 
The botanically accepted name of the Weigelias has 
for many years been Diervilla, but very few gar¬ 
deners have yet accepted that name in practice. 
Notwithstanding the many years they have now been 
cultivated in British gardens no common English 
name has yet been adopted for them, and Diervilla 
is not a name that will readily be accepted by the 
British public. About seven species are known.to 
science, the most of which are in cultivation. It 
does not follow that the oldest introductions are the 
most popular, for D. trifida was introduced from 
North America in 1739, and it is perhaps at the 
present day as rare as any in private establishments. 
The finest are D. grandiflora, D. hortensis and D. 
rosea, the last being perhaps the most widely dissemi¬ 
nated throughout the length and breadth of the land. 
They will grow in almost any soil that is suitable 
for ordinary garden purposes, and can readily be 
propagated by means of the suckers which they as a 
rule throw up freely enough. They can also be 
increased to any extent by means of cuttings taken 
in autumn or spring, the former being perhaps the 
most suitable. Some recommend that they should 
be grown in shady situations, but although they 
succeed admirably under those conditions they can 
also be grown to perfection even when fully exposed 
to sunshine. The mixed shrubbery is usually the 
plac.e to which they are consigned, but they never 
appear to better advantage than when grown on the 
grass in beds, clumps or masses. The improved 
garden kinds, hybrids or otherwise, may be grown 
separately or in mixture. 
Diervilla rosea and D. grandiflora, better known 
as D. amabilis, are very similar in general 
appearance, but the latter has larger flowers and 
larger, more wrinkled and strongly-veined leaves. 
D. rosea was originally introduced from China, and 
is sometimes spoken of as the Japan Honeysuckle. 
Several other species are natives of Japan, but 
although they belong to the same order as the true 
Honeysuckles, yet there are species of Lonicera 
coming from the same country and for which the 
name must be reserved. The flowers of D. rosea are 
rose-coloured, while those of D. grandiflora are 
larger and of a pink hue. In both cases, however, 
they are of a deep red while yet in bud, and always 
retain a darker hue on the outer face ; a red blotch 
runs along the lower side of the tube, 
A large number of garden forms of the above 
species are now in cultivation, and it does not yet 
seem that we have reached the limit of improvement. 
Carrieri is an early flowering sort with large, richly- 
coloured flowers. The buds of Van Houttei are 
red, but as the flowers expand they fade to a peach- 
blossom hue, and white at the tips of the segments. 
Desboisii has red buds fading to pink; but when 
fully expanded the flowers are white, edged with 
pink. The flowers of Madame Conturier are similar 
to those of the last named, but under the same condi¬ 
tions are larger and more delicate in hue. Isolinae 
has white flowers and a yellow blotch in the throat, 
the red and orange having disappeared. There is 
also a variegated variety of.D. grandiflora, having a 
broad but irregular margin of yellow to the leaves. 
Another named .Loozmansii aurea has foliage of 
a golden yellow. There is also a dwarf variety, 
D. rosea nana aurea, with similar but smaller 
leaves. 
Several of the above are suitable for forcing, but 
they are not largely employed at present for that 
purpose. They should be treated in the same 
manner as the Guelder Rose, the double Spirsea 
prunifolia and Viburnum Tinus. Strong heat is un¬ 
necessary, and plenty of ventilation should be given 
in order to keep the young growth short and 
sturdy, otherwise the flowers will be small and short¬ 
lived. The usual plan of growing the Weigelias is 
as a bush, but the above kinds may be used for 
covering walls in the same way as climbers, a suffi¬ 
cient amount of young wood being laid in to insure 
plenty of bloom. June and July are the months 
during which the above kinds are at their best. 
A handsome species, and by no means so common 
as its merits deserve, is D. hortensis, with red flowers. 
The leaves are very large, elliptic, much wrinkled, 
green above, and hoary with tomentum beneath. 
The margins have curiously incurved serratures, and 
by this means alone the species may be recognised. 
The white variety, D. h. alba, is even more choice, 
for with exception of a pale yellow line on the lower 
segment, the flowers are pure white. It may be 
flowered while yet in a very dwarf state, and good 
culture has a wonderful effect upon the size of the 
flowers. In its native country, Japan, the stems attain 
a height of 4 ft. or 5 ft. ; but it flowers finely in 
British gardens when only 2 ft. high. The plant is 
very distinct from either of the above, and should 
soon find its way into many gardens. By reason of 
its dwarf habit it would prove suitable for villa and 
cottage gardens, where the space is too limited to 
admit D. grandiflora and D. rosea, which attain a 
height of 8 ft. or 10 ft. even in this country. 
Another dwarf species is D. floribunda, otherwise 
known as D. multiflora, also coming from Japan. It 
is about 3 ft. high, and flowers in June. The flowers 
are pale purple and tubular, with the mouth only 
slightly expanded compared with any of the above- 
named kinds, with which it can hardly compete, not¬ 
withstanding its free-flowering habit. It is however 
very distinct, and should not be omitted where collec¬ 
tions are grown. A Siberian species about as seldom 
seen in gardens as the last is D. Middendorfiana. It is 
otherwise known as Calyptrostigma Middendorfiana, 
but both names are rather confounding or troublesome 
to all but the botanically-inclined, and those that 
have no difficulty in remembering and pronouncing 
foreign names. The leaves are ovate-lanceolate and 
prominently netted with strong veins. The flowers 
are yellowish-white and spotted with pink on the 
lower segment of the corolla. 
The oldest introduction to this country is D. trifida, 
better known as D. canadensis, by which name it was 
recorded in old books. It is a native of North 
America, and was at first reported from Carolina, 
Newfoundland, and New England, where it grows on 
the tops of the highest mountains, and is therefore 
very hardy. The leaves are of oblong-ovate and of a 
dark shining green. The flowers are small, and pale 
yellow, with the lower segment darker, and are 
produced in clusters terminating the shoots. The 
bush is said to attain a height of 3 ft. or 4 ft., but as 
seen in this country is only half that height. Closely 
similar to the last is D. sessilifolia, but the oblong- 
lanceolate leaves are stalkless and much stained with 
bronzy-red. The clusters of flowers also appear to 
be larger as a rule. The twiggy stems are also of a 
beautiful red. On the whole the two last species 
may be compared to some of the Hypericums as 
far as habit and general appearance are concerned,—

ROSES FOR BUTTONHOLES. 
Some of the Tea Roses are naturally adapted for 
this kind of work on account of their small size, but 
a larger number of others require to be gathered in 
the bud state, when they are literally charming. 
There is certainly a grandeur about them when 
grown to the largest size they are capable of 
attaining, each according to its kind; but they 
are short-lived in that condition and their glory 
is soon gone. Besides their use for buttonholes 
in the bud state, they might be more largely used 
with fine effect amongst cut flowers generally, on 
account of their fresh appearance and their greater 
durability. In the bud state Ma Capucin is a 
salmony-orange flower of the first water. Marie 
Van Houtte, on the other hand, is of a soft yellow ( 
tinted with bronze on the outer petals. Madame de 
Watteville is pink and yellowish, and Rubens of a 
beautiful flesh-colour. For any purpose almost, 
except on the exhibition table, Niphetos is a charm¬ 
ing flower in the bud or half-open state. It never 
seems to vary from the pure or snow-white colour of 
which the name is suggestive. Niphetos is the 
Greek word for a snow shower, The rosy-red hue 
of Madame Lambard is always attractive when 
grown with a proper exposure to air and sunshine, 
The apricot-coloured flowers of W. A. Richardson 
are seen to advantage only when in bud, as fully- 
expanded blooms get open in the centre. The rich 
red hue of the Hybrid Perpetual, W. F. Bennett, 
when in bud is simply charming, and presents a 
striking contrast to all of the above, best seen, of 
course, when in mixture.—S. 
CALCEOLARIA ANGUSTIFOLIA. 
The plant in gardens under this name is a variety 
of C. rugosa, known also as C. integrifolia. The 
type, as well as C. rugosa angustifolia, was intro¬ 
duced from Chili in 1822. Another variety, named 
C. r. viscosissima, was brought from the same 
country ten years later. So seldom does one see 
the unimproved wild forms, whether species or 
varieties, in gardens now that an old face becomes 
interesting. We noted a long line of it the other day 
in the flower garden at Holland House, Kensington. 
It is a shrubby type with pale yellow flowers, freely 
produced in terminal corymbose panicles. The leaves 
are linear, entire, wrinkled, dark-green above, and 
rusty beneath. In habit it is altogether similar to 
Golden Gem, with which everybody is familiar, but 
differs in the narrow leaves, smaller and pale yellow 
flowers, and is later in coming into bloom. It is 
also notable for its hardy constitution, and resists 
the disease to which many of the garden kinds are 
liable, and which sometimes kills them wholesale. 
For this reason alone gardeners should always keep a 
quantity of it in stock. 
BILLBERGIA BARAQUINI ANA. 
There are at least three species of Billbergia in 
cultivation which bear a close resemblance to one 
another, and therefore form a little group by them¬ 
selves. These are B. zebrina, B. Porteana, and the 
plant under notice. The leaves of the latter are few 
in number to a plant 2 ft. to 3 ft. long, deeply 
grooved, spiny at the margin, dark green, and but very 
little striped with grey scales which form so marked 
a feature in B. zebrina. The flower scape is drooping 
or arching, furnished with a number of lanceolate, 
rosy-scarlet, and showy bracts 3 ins. to 6 ins. long, 
below the flowers. The axis amongst the flowers, and 
also the ovaries and calyx, are hoary or white with a 
dense coating of scales. The petals are long, greenish- 
yellow, and rolled back at the tips; they are more 
decidedly yellow than is the case with B. zebrina. 
The anthers and the tip of the style are bluish. Al¬ 
together the flowers are both curious and interesting, 
and assisted with the highly-coloured bracts may be 
considered as decidedly showy. The rate of growth 
of the inflorescence after it begins to push up is 
remarkable. The species is a native of Brazil, and 
may be seen in the Victoria House at Kew. It was 
originally introduced as long ago as 1S05. 
THE KAMTCHATKAN MEADOW SWEET. 
Under favourable circumstances our native Meadow 
Sweet attains a height of 3 ft. or 4 ft., but that under 
notice is double the height, namely b ft: tg § ft, or
