dontoglossum Insleayi was originally introduced by Mr Barker, of Birmin- 
gham, about the year 1838, or 1839, through his collector Ross, who 
Bes met with it in the neighbourhood of Oaxaca, in South Mexico. It flowered 
for the first time in Europe in Mr Barxer’s collection, at Springfield, in the spring 
of 1840, and was named, after his gardener, Oncidium Insleayi. About twelve 
years later it was transferred to Odontoglossum by Dr Linptey. 
As in the case of most other of the earlier introduced Odontoglossums, 
it soon disappeared from cultivation, not being able to endure the stifling heat 
of the stoves in which all Orchids were at that time confined. Viewed in the 
light of our knowledge at the present day, it is marvellous how persistently most 
cultivators ignored the fact that plants from an altitude of five to six thousand 
feet above sea-level were natives of an essentially temperate climate, and must 
be treated accordingly. Probably they were unaware of the facts, and this plea 
may at least be urged in extenuation. 
For about twenty years the species disappeared from cultivation, but in 1863 
it again appeared, and was figured by Mr Bateman in his splendid monograph 
of the genus. With the advent of a rational system of cool treatment, the plant 
was found to grow with the greatest ease, and it has been represented in our 
collections ever since. 
It is one of a natural group of three species, found in the mountains of
