This species is named for Paul Simmler, chief gardener of the Boissier
Collections at Geneva, Switzerland. The plant was introduced in a collection
of orchids from Costa Rica and -flowered in cultivation. Dr. Rose saw
it when in Geneva in 1912 and obtained a small fragment, but he did not
see it in flower.
