a decomposed material, and it is useless to attempt it, hence the necessity 
of repotting any that are in that condition. A sweet, healthy rooting 
material is of the first importance, and to keep it so requires some 
attention from those entrusted with the use of the water pot. 
Lzuias.—The Mexican Lelias are in full growth, and the bright 
weather is to their liking. Only sufficient shade should now be given to. 
prevent scorching. Lelia purpurata, and the hybrids derived from it, 
should enjoy a short rest after their flowering season is passed, and any 
necessary repotting may be taken in hand when new roots are observed to 
be pushing. The cool-growing members of this family, such as L. pumila, 
prestans, Jongheana, Dayana, and others are developing new growths. If 
a light position can be found for them in the Cool house they will thrive 
there much better during the summer months than in the Intermediate 
house. They may remain there until their flowers show, when they may 
be returned to the Cool Intermediate house for the winter. These plants 
may be afforded fresh rooting material whenever they begin to make new 
roots. Comparatively speaking, these plants are of small growth and are 
best grown suspended at a moderate distance from the roof. They delight 
in a reasonable quantity of light and air at all times, with a plentiful supply 
of water to the roots when in full growth. As soon as growth is complete 
only sufficient to prevent shrivelling is necessary. The slender-bulbed L. 
harpophylla, which one does not see much of nowadays, also succeeds in 
the Cool house during the hottest part of the year. 
L2LIOCATTLEYAS AND ALLIES.—There are so many hybrids at the 
present day, and of such complex parentage, which succeed under similar 
treatment, that for the present I purposely put them together. The plants 
I refer to are those now in bloom, or that have just passed that stage. 
They are best kept slightly on the dry side at the roots until new growth, 
and with it new roots, are produced, when any necessary repotting can be 
undertaken. At this season they will take plenty of water at the roots. 
CaTTLevas.—C. Gaskelliana, C. labiata, and others which make their 
growths during the summer months, and produce their flowers during the 
autumn, will have made considerable progress, and already the pseudobulbs 
and flower sheaths are formed. They should receive water whenever they 
become dry, and be placed in a position where they may receive the benefit 
of light and air to consolidate their growth. As soon as these are mature, 
and the flowers commence to push through the sheaths, much less water 
will suffice. C. Mossiz, C. Mendelii, and their numerous varieties have 
now passed out of bloom, and may have any necessary attention as 
regards repotting as soon as root action recommences. C. Bowringiana, 
with its hybrids, may also have attention in this matter when the young 
growths have attained some considerable size and are about to push roots.
