344 THE ORCHID REVIEW. [NovEMBER, 1913. 
leaves removed, flowers neatly staked, and leaves sponged. If thus gone 
over carefully, their beautiful and long-lasting blossoms are set off to great 
advantage. Besides the varieties mentioned there are countless secondary 
hybrids, all of which are worthy and suitable for cultivation in an amateur’s 
house, and I think the best plan is to visit a nursery and select individual 
plants in bloom. 
The beautiful Oncidium tigrinum, which, to my mind, is one of the 
handsomest of any Orchid yet in cultivation, will now be throwing up its 
flower spikes, and must be placed in the warmest and lightest part of the 
house, as otherwise the buds are apt to turn yellow and drop off. If not 
very strong it will be found best to remove the spike as soon as all the 
flowers are open, as otherwise too great a strain will be imposed upon 
weakly plants, and much care would be required to grow them again into 
strong, healthy specimens. The flowers, however, will keep as long in a 
cut state as if left on the plant, providing the stem be cut under water every 
day, and a little salt added to the water, which should be changed daily. 
The above remarks apply to all the species of winter and spring-flowering 
Oncidiums. 
. Where there is the necessary time it will be found a good plan to 
periodically go through the whole collection, sponging the leaves, removing 
any useless pseudobulbs, and in keeping a sharp look-out for all signs of 
insect life. Slugs are unusually troublesome at this season, and therefore 
must be carefully watched for. Bran or fresh lettuce leaves laid at intervals 
on the staging form attractive baits, and many can be caught if a search is 
made with a lantern about eight o’clock in the evening. 
It is now too late in the year to re-pot any plant, as the winter is near 
at hand, and no Orchid ever re-establishes itself satisfactorily at that season. 
Potting should only be done when the roots are active and thus able to 
avail themselves of the new compost at once. 
SUGGESTED ADDITION. 
CYPRIPEDIUM LEEANUM.—This hybrid is most suitable for an Amateur’s 
Cool house, being free-flowering, of easy culture, and low in price. The 
blooms are produced in the winter months, and will keep fresh from eight 
to ten weeks if kept cool and dry. Several fine varieties exist, but in the 
typical form the dorsalsepal is white, with violet dots and a green base, 
the sepals and pouch being yellow, much over-laid by brownish red. No 
other hybrid has probably been so much employed by the hybridist, and the 
secondary hybrids of C. Leeanum are extremely handsome and comprise 
such useful winter-flowering varieties as Actzus, Leander, Lasellei, and 
Tracyanum. In fact over forty distinct hybrids from C. Leeanum are 
recorded in the Orchid Stud-Book, and others have appeared pine, so that 
there is ample material to select from.
