The orchidaceous genus Eriopsis, Lindl., includes about 
six species, all South American, and extends from Guiana 
and Colombia to Northern Brazil and Peru. One of these 
species, E. rutidobulbon, Hook., has already been figured at 
t. 4437 of this work. The species now figured, £. [/elenae, 
Kriinzl., is a native of Peru, whence it was introduced by 
Messrs. Sander and Sons, in whose establishment at St. 
Albans it flowered for the first time in 1897 and provided 
the material on which Dr. Krinzlin’s original description 
was based. In 1894 Messrs. Sander presented one of their 
plants to the Royal Botanic Gardens, Kew, where it throve 
well in a tropical house under the conditions suitable for 
species of Dendrobium, but did not flower until June, 1909, 
when it afforded the material from which our illustration 
has been prepared. Unfortunately the exhaustion resulting 
from the production of its striking inflorescence was so 
severe that the plant has since succumbed,
