Kew in February, 1915, and so permitted our plate to be 
prepared. Planted in a teak basket and suspended near 
the roof-glass, it thrives well under the treatment suit- 
able for members of the genus Stanhopea. Its cultural 
requirements are thus in accordance with its natural 
affinities for, when first described, the genus was noted 
as being allied to Lacaena, Lindl., which in the Genera 
Plantarum was placed in the subtribe Cyrtopodiear, but 
has since been more satisfactorily transferred to the sub- 
tribe Stanhopieae, wherein Sievekingia is most appropriately 
included. The two species from Costa Rica are unknown 
now in orchid collections; those from South America 
appear, perhaps owing to difficulties connected with - 
their culture, to have failed to secure a permanent 
position in our gardens.
