Oncidium macranthum is an evergreen plant, requirmg to be grown in the 
coolest house; indeed, it grows at an elevation of 10,000 feet in the mountains of 
Ecuador, so that the very coolest place in the Odontoglossum house must be chosen 
for its reception. The plant is not a large rooter, so that it does not require an 
extra-sized pot, but it does like to be thoroughly well drained, in order to convey — 
quickly away any excessive moisture that may be given it, and to keep everything 
about it in a thoroughly sweet and healthy condition. For soil use good brown 
peat fibre mixed with a little chopped sphagnum moss, and let the plants be kept 
growing all through the winter months; indeed, it is at this season of the year 
that usually the flower buds are swelling up on the spikes, and which take an 
immense time to come to perfection, It blooms in the spring months and lasts 
a considerable time in full beauty, and if the spikes are trained upon the rafters 
of the house, it will make a good contrast with the white flowers of the — 
Odontoglossums which will be flowering beneath them, and in this manner both 
the Odontoglots and the Oncidiums show themselves to the very best advantage,
