This species came, in 1867, from Director Linden, who 
obtained it from Ecuador or Peru, I believe from the neighbour- 
hood of rich Loxa. I possess a dried flower from Mr. Wallis, 
signed “Ecuador.” It appears that the lot sent to Mr. Linden 
was not inconsiderable. It stands at a very moderate price in 
the Lindenian catalogue of Orchids. We have not only obtained 
twice, at the Hamburgh Botanic Garden, living plants from 
Mr. Linden, but both are even now alive, one a very strong 
mass. As a species it ranks near the Z. macrophylla, Lindl.,
