ORCHID COMMITTEE. 
Dendrobiiun Tliwaitsiae. 
The parentage of this hybrid was D. splendidissimum 
grandiflorum x Wiganiae, and the colour shows the progeny 
to be fairly intermediate. The sepals are of a soft straw 
yellow; the petals are similar, but tinted with the palest rose 
hue on the apical half. The lip has a large brownish-crimson 
blotch on the disc, the rest being yellow finely tinted with 
rose. The plant is evidently of vigorous constitution, and 
flowers freely. Award of Merit: R. G. Thwaites, Esq. (gar¬ 
dener, Mr. J. M. Black), Christchurch Road, Streatham. 
Cattleya Enid magnifica. 
The parentage in this case was C. Mossiae x gigas. The 
sepals and crisped petals are of a soft rose, and good form. The 
lip is of huge size, with an orbicular crimson-purple lamina., 
and rosy much crisped and wavy edge ; the throat is pale 
yellow. A small plant bearing four flowers of handsome size 
was awarded a First-class Certificate. Messrs. Charlesworth 
& Co., Heaton, Bradford. 
Odontoglossum Rossii Low’s var. 
The usual blotches or markings on the flowers of this variety 
are of a pale green, with the faint tint of brown, or the latter 
shade may be entirely absent. It would come into 1 the same 
category as the green Cypripedium lawrenceanum, and C. 
callosum, and is very pretty. Award of Merit: Messrs. Hugh 
Low & Co., Bush Hill Park, Middlesex. 
Bulbopliyllum oculatum. 
The sepals of this very peculiar Orchid are green on the 
outer face, and blotched with purple internally. The flowers 
are produced in a dense quadrangular spike, with a bend at the 
base, so that the small flowers resemble some animal gaping 
as they expand in succession.. Botanical Certificate': H. T. 
Pitt, Esq. (gardener, Mr. W. Thurgood), Rosslyn, Stamford 
Hill. 
FLORAL COMMITTEE. 
Jasminum primulinum. 
We have been waiting for some years for the flowers of the 
above species, ever since we heard of its discovery at Yunnan, 
in China, by Mr. E. H. Wilson, who had been collecting for 
Messrs. J. Veitch & Sons, in China. The species may be de¬ 
scribed as a greatly enlarged form of J. nudiflorum, the flowers 
being as large as a half-crown piece', and clear yellow, much 
darker than a Primrose. The segments are rounded at the 
outer end, generally emarginate, and usually number seven, but 
very often one or two large one® will appear in the centre as 
well as several small ones, making the flower appear semi- 
double. Whether this character will be permanent or whether 
it will even advance so as to form a perfectly double flower 
remains to be seen, but at present there seems to' be a great 
promise that a double variety will soon be forthcoming. The 
better-known J. nudiflorum has been flowering freely in the 
open more or less since December, and proves quite hardy in 
this countiy, though its native countries are China and Japan. 
The new J. primulinum has already withstood 16 degrees of 
frost on a north aspect wall, and may prove to be as hardy as 
the better-known species. If this is so, it will be a valuable 
acquisition, and one of the most important of recent intro¬ 
ductions. In any case, it may be utilised to great advantage 
by cultivating it in pots for flowering in the greenhouse or 
conservatory. The shoots are very graceful, the leaves similar 
to J. nudiflorum, and the large flowers effective, and freely 
produced on quite small plants. First-class Certificate: 
Messrs. J. Veitch & Sons, Limited, Chelsea. 
Magnolia Campbelli. 
The flowers of this Himalayan Magnolia are of great size 
and very showy. The outer six or seven sepals are spreading, 
rose-coloured externally, and white tinted with flesh inter¬ 
nally. The petals are similar in colour or slightly darker, but 
they are nearly erect or form a cup round the stamens. The 
flowers have a peculiar odoiir, though neither too powerful nor 
in any way disagreeable. First-class Certificate: W. E. Gum- 
bleton, Esq., Belgrove, Queenstown, Cork; and Messrs. R. 
Veitch & Son, New North Road, Exeter.. 
Clivia T. E. Arnold. 
A plant of this variety shown bore a truss of enormous size, 
and the flowers, as well as their texture, were quite in keeping 
with the plant. The segments are obovate, much overlapping, 
orange scarlet, and yellowish-white in the throat. Award of 
Merit: Lady Bathurst (gardener, Mr. T. Arnold), Cirencester 
House, Cirencester. 
Pinguicula caudata snperba. 
The above Mexican type of Butterwort is one of the showiest 
and most interesting of the genus from a horticultural point of 
view. The flowers are of large size, with obovate, rounded 
segments, and a long tail or spur attached to the base. The 
leaves are very similar to those of our native species of Butter- 
wort, and similarly arranged in rosettes. The variety under 
notice differs from the- type hr having flowers of a much darker 
hue, being of a rich carmine-rose. When last brought into 
notice in gardens it made its appearance under the name of P. 
bakeriana, and was figured under that name in one of our con¬ 
temporaries. Award of Merit: J. T. Bennett Poe, Esq. (gar¬ 
dener, Mr. J. Downes), Holmwood, Cheshunt. 
Lachenalia Ruth Lane. 
The flowers of this new form are rather larger than those of 
L. Nelsoni, but they differ in colour. The ground colour is 
yellow tinted with red at the base, and the margin of the 
large-spreading inner segments is bronzy-purple. (Award of 
Merit.) It was exhibited by F. W. Moore, Esq., of the Glas- 
nevin Botanic Gardens.

Hardy Cypripediums. 
These outdoor Orchids are not too often met with in a 
healthy condition, perhaps because their likes and dislikes are 
not sufficiently studied. True, some species and their varieties 
are more tender than others, so much so that an annual suppl} 
must be obtained if,a fair collection is kept; but many will 
thrive for years, and some increase wonderfully, if a home is 
prepared for them in a shady, moist position, where plenty of 
peat, and leaf mould is provided for their root®. 
All the varieties of “ Lady’s Slippers ” cannot be noticed here, 
but. a few known to succeed are the following: C. aeaule yields 
purple-rose flowers on stems about 8 in. high, and likes a little 
sphagnum amongst the compost. The English Lady s Slipper, 
C. Calceolus, yields purple-brown and yellow flowers on leafy 
stems about a foot high. It flowers early, and likes fibrous 
loam and old lime rubble mixed in the bed. C. californicum is 
a very pretty sort, having white, tinted rose, and yellow flowers, 
likes sphagnum and moisture. The white Lady’s Slipper, C. 
candidum, grows about 1 ft. high, having white flowers, which 
show a little purple. It likes decayed leaves mixed with its 
rooting compost. Other good and distinct varieties are C. guff 
tatum, C. japonicum, C. macranthum, C. occidentale, C. parvi- 
florum ; and last and best, C. spectabile, sometimes called “ The 
Mocassin Flower,” is, without question, the prettiest, most flori- 
ferous, and easiest grown of the lot. It is impossible to over¬ 
praise the merits of this lovely species. It loves a deep bed 
of peat and decayed leaves in a shaded position, with constant 
moisture in summer. A suitable bed, with a trickling stream 
passing over it constantly, is the ideal home of this gem; but 
protection from the east winds of spring must be provided, 
as these, rather than our worst frosts, destroy our hardy Cypri¬ 
pediums. I should not, perhaps, say “ our,” with the exception 
of the English species, C. Calceolus ; the others hail from N. 
America, C. guttatum from Russia, and occidentale from Cali¬ 
fornia. Ulsta.
