Note :

1. The first to discover this species was J.J. Wurdack in 1962. It was given a manuscript name by Paul Hutchison, but has never been described. In 2000 Myron Kimnach found it again at the type locality and on shaded cliffs along the Río Pomacocha, in the South of the province of Chachapoyas.

2. E. wurdackii differs from E. utcubambensis  (also from the South of Dept. Amazonas) by its very long pedicels and a more lax rosette with bigger leaves.
