N\ ASDEVALLIA ROSEA was discovered in 1842 or 1843, by Theodore Hartweg, 
+ near Loja in Ecuador, and from dried specimens collected by him it was first 
named and described by Dr. Lindley in 1845. No importation of living plants was 
effected until 1880. when Consul Lehmann sueceeded in bringing home a quantity. In 
ISS2. the first living flowers seen in Europe were produced from these plants distributed 
wnong various private collections of Orchids. The flower varies slightly in size and in 
brillianey of colour, and the plant drawn for the accompanying plate was considered by 
Professor Reichenbach to be a rather narrow and dark-flowered variety. The stem is 
usually one-flowered, although ina wild state stems bearing two and even three flowers 
have been met with, and have also occasionally appeared in cultivated plants. 
Consul Lehmann sends me the following note: 
Masderallia rosea evows on the Eastern Andes from the southern part of Colombia to 
the south of Ecuador at an elevation of 2,800 to 3,200 metres (9,100 to 10,400 feet). In 
1877 I met with it on the Voleano Tunguragua, and subsequently in the Eastern Andes 
of Cucnea and Loja, in the south of Ecuador. It grows on trees in dense and damp 
woods. The annual mean temperature of the region ranges between 10° and 12°°5 
Centigrade (50° to 4° Fahrenheit). 
The only plants existing in Europe originate from an importation of mine ce i 
1ss0, from the Andes of Pasto in Colombia. In its natural habitat the plant flowers in 
October and November, and also in June, July and August.
