O. trulliferum ; pseudobulbis elongatis ovalibus com ressis 2-3-phyllis foliis 
ovalibus feré equalibus, scapo radicali rigido semel ramoso, sepalis laterali- 
bus distinctis superioribus petalisque obtusis concavis, labelli lobis lateralibus

alis integerrimis ovatis obtusis. 
This addition to the extensive genus Oncidium is a native 
of Brazil, whence it was imported by Messrs. Loddiges, with 
whom it flowered in September, 1838. 
The pseudo-bulbs are represented much diminished in 
the accompanying plate; they are in fact six inches long, 
and the leaves themselves are scarcely longer; they are 
pressed almost flat, so that although fourteen or fifteen lines 
broad, they are not more than three lines thick (fig. 2.). 
The scape is stiff, erect, and branched in a simply pin- 
nated manner, each branch being covered with flowers from 
the base to the apex. The figure of the lip (fig. 1.) is ve 
uncommon ; its middle lobe is produced into a segment muc 
like a bricklayer’s trowel, at the base of which there stands 
a strong tooth ascending, notched at the side, and terminated 
by a little notched appendage ; this tooth rests by its back 
upon a tumour covered with regular warts, and forming the 
centre of three such tumours, the lateral ones standing nearer 
the base of the labellum, with a smooth wartless hollow be- 
tween them. 
In cultivation it requires the da
