Note :

1. The wild origin of E. elegans var. kesselringiana is not known, however there is no doubt, that it has a wild origin. It has been described from plants the seeds of which had been collected by F. Ritter and sent to his sister H. Winter in Frankfurt who offered the seed for many years, so it must have become widespread throughout Europe. Therefore the majority of the plants circulating in Europe and having been exported from Europe worldwide have to be re-named : They are not E. albicans Walther but E. elegans var. kesselringiana v. Poellnitz.

2. E. elegans var. kesselringiana is not a synonym of E. albicans as stated by E. Walther in his description of the latter.  The two plants differ not only considerably in size but above all in the shape of the leaves - E. albicans having a distinct slender apiculus, totally absent in E. elegans var. kesselringiana.

3. E. elegans var. kesselringiana differs from E. albicans in

- leaves only up to 3 cm long and 1.5 cm broad / albicans 3 - 5 cm long and 1.5 - 2.5 cm broad and with a distinct slender apiculus, lacking in var. kesselringiana,

- pedicels only 7 - 8 mm long / albicans 14 mm long and

- sepals to only 4 mm long / albicans to 10 mm long.
