ONCIDIUM. Botanical Register, vol. 13. t. 1758. 



O. trulliferum ; pseudobulbis elongatis ovalibus compressis 2-3-phyllis foliis 

 ovalibus fere aequalibus, scapo radlcali rigido semel ramoso, sepalis laterali- 

 bus distinctis superioribus petalisque obtusis concavis, labelli lobis lateralibus 

 nanis rotundatis intermedio truUiformi serrulato, crista verrucosa medio 

 depressa laevi antice dente ascendente serrato apice appendiculato, columnae 

 alis integemmis 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. I.) is very 

 uncommon ; its middle lobe is produced into a segment much 

 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 damp stove. It is easily 

 managed ; growing freely either in a pot with the usual soil, 

 October, 1839. x
