should always be procured either newly-imported or semi-established, and 
then one has a chance to grow it. Its nature is to grow in a manner, that, 
to anyone unacquainted with it, would appear to be upside down, so when 
fixing it to the block the leaves should always be pointing downwards. It 
is essentially a heat-loving plant, and should therefore never be removed 
from the warmest department. It should be supplied with a fair amount of 
water during the summer, its growing season, but at all other times, a very 
little water indeed should be given, and the plant should always be 
suspended in the lightest, the airiest, and the hottest part of the house. 
Under such conditions alone can O. Jonesianum be grown successfully. 
Oncidium ampliatum is also a hot-growing kind, though not by any 
means difficult. It is best accommodated in baskets or pans, suspended, 
and should be grown in peat with a little sphagnum moss, paying due 
regard to the watering, as before advised, especially during the winter 
season, 
Oncidium Papilio and O. Kramerianum are two other well-known old 
stove species, and should have exactly similar treatment to the last-named, 
with the exception that they may be grown equally well when fixed on rafts 
or blocks of teak. I may mention that, if at any time when the block 
system is adopted for the culture of any Orchid, the wood should become 
decayed, or the plant overgrow its sides, necessitating a new block, that the 
old one should be soaked in a bucket of water for about half-an-hour before 
any attempt is made to take off the plant. The roots will then very readily 
release their firm hold, and come away without being much broken about. 
The plant should be fixed at once on to the new block, and kept well 
moistened for several weeks afterwards, so that the roots may again be 
induced to take hold. I lay great stress upon the roots, knowing that it is 
absolutely impossible to grow Orchids well unless these are kept alive and 
in a healthy state. 
Oncidium macranthum, lamelligerum, superbiens, zebrinum, and 
Leopoldianum I find always grow best treated as Cool house Orchids, and 
exactly the same as the cool Odontoglossums. They love the cool moist 
atmosphere, the air, and the shade which that house affords them. Another 
well known and greatly admired species is O. tigrinum. This generally, 
also, does very well potted up and subjected to the same treatment, though 
in this case an improvement is no doubt effected in the long run by giving 
it a trifle more warmth during the long winter months. O. cheirophorum 
and Q, ornithorhynchum, two neat and pretty species, may also be similarly 
Spoken of, as also may O. cucullatum and O.c. Phalenopsis. The pretty 
little climbing species, O. Limminghei, must be supplied with a neat raft to 
©orrespond, and is best grown in the warmth of the Intermediate house the 
ies Whole year round.
