The interesting Odontoglosswm now figured is a native 
of Ecuador, where it was first discovered about eighty 
years ago by Mr. T. Hartweg, when collecting plants for 
the Royal Horticultural Society of London. ‘The locality 
of the original specimens was Mount Paccha, near Loxa, 
on the western slopes of the Andes opposite the Gulf 
of Guayaquil. For many years this species, which 
Lindley had described as Q. cristatum, was only known 
from the original herbarium specimens, but in 1847 
living plants of an Odontoglossum, collected in the Loxa 
district by Mr. G. Wallis, were sent to the horticultural 
establishment of Mr. Linden at Brussels; these plants, 
on flowering, were recognised as identical with Hartweg’s 
one. At a later date the late Mr. Consul Lehmann 
JuLy-SEPTEMBER, 1919.
