lobe of a somewhat lighter shade. The crest, which consists of several rather 
prominent lamellae, is white. The stout falcate column-wings are dark purple. 
Oncidium lamelligemm grows on the branches of the forest trees in its native 
country, affecting situations which are cool and moist. It should therefore be 
placed in the cool house, with O. macranthum and others that occur naturally 
in the same région. In the Odontoglossum house it is said to grow admirably, 
under the same cultural conditions as is given to Odontoglossum crispum and 
its varieties. Very little fireheat is required ; the plants should be kept cool 
and moist, and as much air admitted, both by day and night, as the outside 
température will permit, thus endeavouring to imitate natural surroundings as 
nearly as the means at disposai will allow. 
Oncidiums of this section, when once established, are said to dislike having 
their roots disturbed, and these being thick and fleshy are very liable to injury 
unless great care is taken in removing old soil and renewing it. Shading should 
also be carefully attended to, which is said to be the secret of success in main- 
taining the rich deep green colour of the leaves. 
The accompanying plate was prepared from a fine specimen which has 
recently flowered in the collection of Charles Winn, Esq., of The Uplands, 
Selly Hill, Birmingham.
