JUNE, 1912,] THE ORCHID REVIEW. gt 
ORCHIDS AT THE ROYAL SOCIETY’S CON VERSAZIONE. 
AT the Conversazione of the Royal Society, held at Burlington House, 
Piccadilly, on May 8th last, there was an interesting exhibit of hybrid 
Odontoglossums and allies, with their parents, by Mr. R. Allen Rolfe, A.L.S. 
The flowers were shown in two shallow glass-covered cases, and arranged 
in such a way that each hybrid was placed between its two parents, so as to 
admit of ready comparison, and bring out the intermediate characters. 
The series comprised the following :— 
Odontioda Charlesworthii (Cochlioda Neetzliana xX Odontoglossum 
Harryanum). 
Odontonia Lairesseze (Odontoglossum crispum X Miltonia Warscewiczii). 
Odontoglossum Charlesworthii (triumphans X Harryanum). 
Odontoglossum excellens (nobile X triumphans). 
Odontoglossum Rolfez (nobile x Harryanum). 
Odontoglossum Thompsonianum (Edwardii X crispum). 
Odontoglossum Ossulstonii X nobile (with both parents). 
The latter is a secondary hybrid, of which three forms were exhibited to 
show the variation of secondary hybrids from the same capsule. 
The flowers exhibited were from the collection of W. Thompson, Esq., 
Stone; R. G. Thwaites, Esq., Streatham; and Messrs. Charlesworth & 
Co., Haywards Heath, who had kindly sent them for the purpose of the 
exhibit.
