- OcTOBER, 1914-] THE ORCHID REVIEW. ae 
Cymbidiums are not fastidious concérning temperature, but any examples 
pushing up their flower scapes may be placed in the Cattleya house with 
advantage. None should be allowed to suffer from dryness at the root. 
Mittonia Roeztu.—This plant somewhat resembles M. vexillaria, 
except that the foliage is not so broad, but it does not prove so amenable 
to cultivation as that popular species. Its constitution is not so strong, 
and therefore will need a little more attention, especially after being 
repotted. Some of the plants will commence to grow at this season, and 
any repotting may be-done if such an operation is deemed necessary. The 
same kind of soil can be used as advised for M. vexillaria. A light positicn 
should be chosen either in the Cattleya house or at the warmest end of the 
Intermediate division, and water must be applied sparingly until well into 
the New Year. 
DIsA GRANDIFLORA should be repotted some time during the present 
month, and for general treatment, compost, &c., I would refer my readers 
to our August number. If any flowers have been fertilized, the seed pods 
will soon be matured, and directly they burst the seed must be sown. 
They will germinate if sown around an Odontoglossum, Cypripedium, or 
Disa, providing the surface is free from sphagnum moss or other growth 
that 1s likely to choke the seedlings. A suitable temperature is 60°, and on 
no account must the plants get dry. Ifthe seed is fertile, germination will 
take place in a few weeks, and when two tiny leaves are formed they can 
be pricked off into store pots. Keep the seedlings in an average temperature 
of 60°, pot on as root action increases, then the strongest will bloom in 
about two years from the time of sowing the seed. Thrip is most trouble- 
some, especially in the early stages of development, and it must be held in 
check either by dipping the seedlings or vapourising the division. I am 
told that the beautiful D. grandiflora is getting rather scarce in its native 
habitat, so it behoves growers to raise a batch of seedlings. A large 
Percentage will come true, in fact the proportion of really bad forms are 
Conspicuous by their absence. 
PHAL&Nopsis, VANDA, AERIDES, &c.— With the shorter days upon us, 
this group of bulbless Orchids will need less water, both at the root and in 
the atmosphere. When the tips of the roots are sealed over, the plants 
will only need water in sufficient quantities to prevent the leaves showing 
Signs of distress. All should be given a light position, and when the 
Phalaenopsis begin to produce spikes a little more water can be allowed. 
Slugs are extremely fond of the succulent leaves and spikes of this beautiful 
8enus, and unless a sharp watch is kept fine plants are soon ruined. 
Lycastr SKinNERI.—Most of these are completing their season's 
Stowth, but any backward plants may be placed in a warmer house until 
the pseudobulbs are developed. Although they will thrive in the Cool
