ODONTOGLOSSUM OERSTEDII MAJUS SUPRA. 
We have already figured a great number of forms of this beautiful and popular 
genus in the Orcurp Axum, these for the most part being large-flowered and 
showy kinds. The subject of our present plate, however, belongs to the smaller 
section, and can neither lay claim to size nor showy colours, but it is so chastely 
beautiful that we do not hesitate to impress the value of it as a cultivated plant 
upon the minds of every grower of Orchids. It is dwarf in its habit of growth, 
and therefore requires but little space for its accommodation. It is very free- 
blooming, whilst its chaste waxy white flowers remain long in perfection, either left 
upon the plant or in a cut state, and in the cut state they may be used as gentle- 
men’s coat flowers, or they may be utilised for the embellishment of ladies’ hair, or 
when made up into shoulder sprays, in either and in all positions, they produce 
an elegant effect. 
The sketch of the plant here figured was taken in the Victoria and Paradise 
Nurseries from a plant in our collection ; it represents the major variety of the 
plant, which differs from the typical species in size only. 
Odontoglossum Oerstedii majus is an evergreen plant of dwarf habit; its pseudo- 
bulbs are ovate, bearing a single oblong leaf, which tapers into a long footstalk at 
the base, and it is usually from three to four inches in length by one in breadth, 
both bulb and leaf being of a rich deep green. The scape is produced soon after 
the bulb is mature in size, and is usually longer than the leaves, bearing from two 
to five flowers, which measure individually an inch or an inch and a half across, 
and are delicately fragrant. The sepals and petals are spreading and bluntly oblong,
