watered ; it will bloom and complete growth without injury. I 
never heard of a Rose bush treated thus successfully ; but I have 
often been asked incredulously, “ Can these Lilies really be grown 
out of doors ? ”— Alexander Wallace, M.D., Colchester. 
Cattleya Pbecivaliana. 
This is a grand and very free winter flowering Cattleya. Out 
of a small consignment had a couple of years ago one is a long way 
ahead of the others, which have all flowered. The plant in 
question bloomed in January, 1892, and again in the correspond¬ 
ing month of this year, and is still flowering. The petals and 
sepals are the same colour, but much larger than are those on the 
other plants, while the lip is also larger and the colouring very 
rich—rosy-pink and purple, and edged with white shaded with 
pink, the throat being a deep orange with dark base, and 
fringe. 
This Cattleya is a good grower, and, together with the several 
varieties of C. Gaskelliana and C. Trian^, help to make the house 
gay during the present time of year. Plants potted firmly and 
well up in the pots in a mixture of sound fibrous peat and 
sphagnum moss, and good drainage being afforded, make a free 
growth when given plenty of heat and atmospheric moisture during 
the summer months. The material about the roots should be 
kept uniformly moist during that period, and afterwards well 
maturing the growth being all that is necessary from a cultural 
point of view to achieve satisfactory results in flowering.—H. W. W. 
Phaius roseus. 
This very distinct Phaius was collected by the Right Hon. 
the Earl of Scarborough. The habitat, says the Keio Bulletin, 
is not absolutely known, but it is supposed to be West Tropical 
Africa. It flowered in Lord Scarborough’s collection in Decem¬ 
ber last, and was sent to Kew for determination. The flowers 
are of a delicate light rose shade, the lip somewhat marbled 
with white spots, the disc with a white hairy fleshy keel and a 
minute tooth at the apex, and the spur deep yellow. In fading 
the flowers pass to a light orange-buff shade. It would be the 
second species discovered in Western Africa. 
Pholidota Lugardi. 
This species is allied to P. articulata, LinclL, but is altogether 
a more robust plant, more erect in habit, and larger in ail its 
parts. The sepals and petals are semi-pellucid white, and the sac 
of the lip pale flesh-coloured, the keels unequal and buff-coloured, 
and the base of the auricles deep yellow. It flowered in the 
collection of Sir John Kirk of Wavertree, Sevenoaks, in June, 
1890, when he forwarded it to Kew for determination, together 
with a living plant, which has since flowered. It is one of a 
large collection made by Captain Lugard in Western Burma —- 
(^Kew Bullethi). 
Phaius tuberculoses. 
A SPECIMEN of this rare and beautiful Phaius is now flowering 
in the warm Orchid house at Kew. Unfortunately this species has 
proved very intractable under cultivation, and, as most growers 
experience great difficulty in preserving it in even moderate health, 
a w’ell flowered plant may be looked upon as a triumph for the 
successful cultivator. The Kew plants are grown on Tree Fern 
stems, with living sphagnum about the rhizomes, in a hot, moist, 
shady corner of a propagating pit. 
P. tuberculosus is a comparatively recent introduction. The 
first plants brought to this country from Madagascar were sold at 
Stevens’ Rooms in 1881, and realised high prices. It first flowered 
in England in the same year in the collection of Sir Trevor Law¬ 
rence. Since then many Orchid growers have tried to overcome 
the difficulties of its cultivation, most of them with but indifferent 
success. In general appearance this species differs considerably 
from its allies. It has a creeping stem from which spring the 
slender pseudo-bulbs with narrow leaves 6 to 9 inches in length. 
The erect spikes bear from four to eight flowers about inches 
in diameter. The beauty of the flower lies chiefly in the lip, which 
is three-lobed and of considerable size. The middle lobe is white 
tinged with rosy purple, the lateral lobes are larger and curve 
inwards, colour dull crimson, freely veined and spotted with golden 
yellow. It is undoubtedly the finest species yet introduced.—

CalanTHE gi5as 
The number of bold and striking Calanthes is not great, 
consequently there is little fear of so fine a hybrid as C. gigas 
passing unnoticed, and it is not surprising that when exhibited by 
Messrs. Veitch & Sons at the Drill Hall on January 17th it should 
have received marked attention. By common consent it took 
rank as a great acquisition, and a first-class certificate was awarded 
to it by the Orchid Committee. The plant is the result of a cross 
between C. Sanderiana gigantea and C. vestita grandiflora. It is 
bold, vigorous, and effective, the stout spike containing numerous

handsome flowers, the sepals and petals of which are ivory whitCj, 
and the lip rich rose. Fig. 24 represents it. 
DISCUSSION ON APPLES. 
Unctuous Apples. 
Some time ago criticisms appeared on my use of the term “ unctuous.” 
I think it is correct. It means of the nature and quality of an unguent 
—oily or greasy to the feel. The unguent on Apples is an exudation 
slightly sweet and adhesive. My object in touching upon the subject 
again, however, is not to give information, but to obtain it. There are 
both fruits and vegetables which produce wax upon their surface. 
Wax is a fat produced from sugar or its relatives. In that case it 
would be as proper to call the exudations “ unctuous ” as it would 
“ glutinous.” There is, perhaps, no difference in the mechanical or the 
chemical change of honey or sugar into wax by the bee from that of 
the fruit or vegetable, or of any animal that produces fat. The chemist
