Oncïdïûm, Srvarlz. Derived from ogkos, a tumour ;
the plants belonging to this genus have warts,
tumours, or other excrescences at the base of the
labellum. Linn. 20, Or. 1, Nat. Or. Orchidacece.
This is an extensive and very handsome genus of
plants, every one of which is highly deserving a
place in every collection. 0. papilio bears a striking
resemblance to a butterfly on the wing. 0.
altissimum throws up from fifteen to twent y flowerspikes,
producing as many as t7V0 tho^isand flowers,
t h e colour of >vhich is yellow spotted with brown,
and there is the splendid O Lanceamim, one of the
most prized in this valuable genus; but to particularise,
where all are remarkable either for the
beauty or the singularity of the flowers, would be
invidious. The large-leaved kinds do best when
grown in rustic baskets, which can readily be suspended
from the rafters of the house ; the basket
should be made of small pieces of oak nailed together,
or holes may be bored, and a piece of strong
wire run through near the end of each, and fastened
a t the bottom. Some moss and rotten wood should
be placed in the bottom previous to putting the
plant in, in doing which, care must be taken not to
insert the plant too deep. Moss and rotten wood
must surround the roots of the plant, but should
not on any account be raised higher than the roots
of the leaves, or they will be liable to damp off.
The small-growing kinds, as O. iridifolium, should
be fastened on wood, and treated as the Burling'
tonias. The other kinds, as O. 'papilio and O. altissimum,
require to be potted similarly to the genus
