HE treatment needed by the occupants of a Cattleya house this month 
will be much the same as was advocated for May, with perhaps a 
little additional attention with respect to watering, damping down, and 
shading. 
CaTTLEYAS.—C. Mendelii and Mossiz will now have finished flowering, 
and, should repotting be needed, this must be performed at once, for if. 
delayed until the hot weather sets in the plants do not always make such a 
satisfactory start. The method employed, advised in the March Calendar,. 
must be strictly observed, except that very firm potting is needed by these 
two species. Where large specimens are possessed, it is not a good plan to 
merely replace them in pots or pans of larger size, as much waste room is 
occupied by the old back bulbs. The following is the best method: 
Carefully divide the specimen, then leave three old bulbs to support each 
new growth and cut the remainder away, as well as any dead roots. Then, 
when potting, arrange each piece so that the new growths are growing 
away from each other, and towards the rim of the pot. If treated in this 
way compact specimens of five or six leads can be accommodated in 
comparatively small receptacles, whereas old specimens, if not re-made 
every three or four years, become unwieldly and merely a collection of an’ 
enormous mass of old useless bulbs, which will fail to produce a propor- 
tionately larger number of leads than a carefully re-made plant in a pot 
half the size. 
THRIPS are sometimes a source of trouble this month, owing to the 
advent of warm dry weather, but an occasional spray between the pots and 
on the floor with a solution of a good insecticide will prove effective. 
VANDA C#RULEA should now receive attention, if beginning to root, by 
the removal of some of the topmost crocks, and placing in their stead some 
green living sphagnum moss. Syringe over the leaves every morning and 
evening, and give water at the root whenever the moss seems dry. 
L&LIA ANCEPS is now beginning to start again into growth, and may be 
Tepanned if necessary. Osmunda fibre and sphagnum moss are needed for 
Compost, and a good way of keeping these plants firm in their soil 1s to peg 
the rhizomes down by copper wires bent into the form of hairpins. By 
this means quicker root action will be made in the new soil, through the 
Toots being thus kept in close contact. 
SUGGESTED ADDITION. 
CaTTLEyA EMpRESS-FREDERICK.—Since the parents of this hybrid are 
C. Dowiana aurea and C. Mossie, it can be easily inferred that the
