than twenty years ago a white Lady’s Slipper Orchid was beyond the wildest dreams of even enthusiastic orchidists, 
so that when the tidings reached this country that Mr. d’Almeida had discovered Cypripedium niveum, a white flowered 
species, in one of the unexplored islands of the Malayan Archipelago, the account was scarcely credited. Its near 
relative, Cypripedium concolor, already existed in gardens, and when the newly found treasure arrived it was considered 
by some to be only a form of that species, the foliage of the two being so nearly alike, but the flowering of C. niveum 
soon after proved that the description of the novelty given by its discoverer was not exaggerated. We have in this 
Cypripedium a plant handsome in foliage, with a flower of exqui 
ite beauty, both as regards its form and colour. It is 
undeniably the gem in a genus rich in beautiful plants, and ever since its introduction it has deservedly been one of the 
chief favourites in the Orchid house. Fortunately, it is not a difficult plant to manage now that its requirements are 
known; the information given by botanical collectors respecting the conditions under which the plant grows wild has 
been a great help to orchidists. One of our own collectors, J. rstermann, sent us some valuable notes respecting this 
Orchid. He says that it inhabits the islands of Lancavii, near Penang, in Siamese territory, and grows there on 
limestone mountains, generally on the western sides where it is not much exposed to the sun 
rocky hills are crowded with it.. It is seldom found growing on perpendicular 
the climatic conditions of the home of C. niveum, Férstermann says that the hottest months are April and May ; the 
coldest period being from December to March, during which time the thermometer is often as low 55 deg. F., and it is 
then that the plant is at rest. In April and May only a few light rain showers occur, but in June the rainy season 
commences and continues till November, and it is during this period that the Cypripedia inhabiting this region are in 
active growth. In cultivation the treatment of this Orchid must therefore be based upon the conditions under which it 
grows naturally as regards the periods of rest and active growth. It succeeds best in an East Indian house, on the south 
side, and during active growth from April till June the temperature may range from 70 deg. to go deg. F. with sun heat. 
The plant requires abundance of water during this period, and an occasional syringing overhead will be beneficial. As 
autumn advances the waterings must be gradually lessened until in winter, when the pl 
, and often the crevices of the 
rocks as are other Cypripedia, With regard to 
ant will be quite at rest, little or 
ature soon induces decay in the leaves and crown of 
no water is required, as excessive moisture combined with low temper: 
the plant. A well drained shallow pan is best for it, and the soil should consist of turfy loam roughly broken, equal parts 
of broken charcoal and soft limestone, and just sufficient co; 
arse sand to keep the compost open. This treatment will 
conduce to strong, vigorous plants that should produce abundant crops of flowers during the early summer months, 
remaining in perfection for several weeks. The flowers of C. niveum vary considerably as regards size, form and 
spotting. The variety herewith illustrated is remarkable for its | 
arge flowers, broad sepals and profusion of spotting, and 
is in fact the finest form yet introduced. ‘
