In 1860 Reichenbach described as Stanhopea costaricensis 
a Costa Rica orchid which flowered that year with 
Consul Schiller at Hamburg. The plant so named was 
subsequently lost and the species was known only from 
the original diagnosis. Towards the close of 1915 Mr. 
C. H. Lankester sent to Kew from Cachi in Costa Rica 
some interesting orchids collected by himself. One of 
these is a Stanhopea from moist and cool localities 
4000 feet above sea-level, which flowered in July, 1916. 
It thrives, like other species of the genus, when grown
