THE ORCHID REVIEW. 337 
OGODONTOGLOSSUM MACULATUM THOMPSONIANUM. 
THE accompanying illustration represents a flower of the remarkable 
Odontoglossum maculatum Thompsonianum, from the collection of W. 
Thompson, Esq., Walton Grange, Stone, to which a First-class Certificate 
was awarded by the Royal Horticultural Society at its meeting held at 
Chiswick on July 16th last. It was recorded in our report at page 252 as 
“an exceptionally large and handsome form, far superior to anything we 
have yet seen. The inflorescence bore eight flowers, which measured three 
inches in diameter across the petals, and the segments were very broad and 
richly coloured.” The illustration, which is from a photograph taken by 
Fic, 49. ODONTOGLOSSUM MACULATUM THOMPSONIANUM. 
Mr. H. J. Chapman, and kindly sent to us, gives a graphic idea of its 
remarkable features, and we may add that in all other respects it conforms 
to the normal type of the species. We do not know anything of its previous 
history. The species is one of the least variable in the genus, both in size 
and colour, and we may add that it is one of the most easily grown of the 
Mexican kinds.
