We have in Odontoglossum Londesboroughianum one of the most distinct and 
brilliantly coloured of the Odontoglots, for there are but few of the species that — 
we have in our plant stoves which produce flowers of a bright golden-yellow colour. 
There are many varieties of it dispersed through different collections, the individual 
forms varying in the size of their flowers and in the depth of their colour, some being 
of a paler yellow than others. The form which we here illustrate is a very good 
ev and was received from the fine collection of H. J. Buchan, Esq., Wilton House, 
Southampton. Under the care of Mr. Osborn, the gardener at Wilton House, it 
a bloomed freely, and, with its long graceful spikes overhanging the foliage of 
other plants, it is found to have a charming effect. It is also extremely useful 
when cut for ornamenting vases, as in these days of eestheticism yellow always 
Proves an acceptable colour in floral decoration. ‘The blossoms, moreover, have a 
brilliant effect when tastefully arranged in vases, if used amongst flowers of other 
*ppropriate contrasting hues. : : :
