For the introduction to English collections of the 
remarkable New Guinea species of Bulbophyllum now 
figured, orchid growers are indebted to Messrs. Sander 
and Sons, St. Albans, by whom it was publicly exhibited 
in July, 1915, under the name B. Balfourianum. The 
plant in question thereafter was added to the collection 
of Mr. H. T. Pitt, Rosslyn, Stamford Hill, to whose 
courtesy we are indebted for the material for our plate 
which was kindly supplied when the plant was in blossom — 
in June, 1919. The name under which the species has 
thus found its way into cultivation is not, however, one 
ApriL-JuNE, 1920.
