orange-scarlet colour. These flowers are produced during the winter and spring 
months, and last for several weeks in perfection. 
The species is a native of New Grenada, where it is found at the great 
. elevation of 8,000 feet, consequently it will grow well with Odontoglots under cool 
treatment. Some years ago it was very rare, but now, thanks to our collectors, 
it is more plentiful, and hence has become popular. It is a most important 
decorative plant on account of its colour, which, as a contrast, is especially useful 
when placed amongst the Odontoglots. We have found it most effective when it 
is brought ito close association with the delicate colours of O. Alexandre and 
O. Pescatorei the effect obtained by the intermixture is altogether charming. 
The Ada requires the same treatment as the Odontoglots. The potting material 
best suited to its growth is good fibrous peat, with plenty of drainage. It will 
thrive either in a pot or in a basket, and in potting it should be well elevated 
above the rim, so that the roots can work freely among the material in which it 
is potted. The soil should be kept moist during the growing season, but on no 
account must the moisture be allowed to become stagnant, a condition which can 
be prevented by using charcoal mixed with the peat, which will keep the drainage 
open, and allow the water to pass off. If the soil should by any mischance 
become soddened it must be removed and fresh soil made use of, the roots at the 
same time being well washed previously to repotting. 
Shade is very essential to the well being of the foliage, as the leaves are apt 
to go spotted if the sun is permitted to shine upon them. In its native country 
it is found in shady places, and hence will not bear full exposure, although in its 
artificial home it likes all the light possible. 
Aéripes Lospi AINswortutt.—We have received a grand spike of this beautiful 
Orchid from R. F. Ainsworth, Esq., M.D., of Lower Broughton, Manchester. It is 
one of the darkest and best varieties that has come under our notice. The same 
plant was exhibited a few years ago at the Royal Horticultural Society's Show at 
Preston, and it was the admiration of every one who saw it. Mr. Mitchell, the 
gardener, informs us that it blooms in the same style every year. The spikes are 
more than two feet long, and well branched, while the colour of the flowers is very 
bright and effective, so that it makes a fine exhibition plant. This variety is much 
darker and brighter in its markings than the type.—B. 8. W.
