the rose shown hers is that of a deep cerise pink not a light pink.either the description is wrong or the photo is incorrect.In this case, the photo is definately wrong.
The original 'Asepala' alias 'Sans Sépales' isn't extinct at all! 'Asepala' is well and fine under its true name at L'Haÿ. In fact Jules Gravereaux added twice this variety in his collection:
First under the French name : 'Sans Sépales' (originally kept at L'Haÿ in the bed LXXV, B22), then mislabelled in the collections after him, during the 1990's and inexplicably by 'Brennus' (perhaps due to the extreme curators negligence at L'Haÿ).
Second under its Latin name 'Asepala' (bed LXXXI, B19), it came back indeed later through some exchanges with the USA during the late Gravereaux years.
The 'Sans Sépales' however has substituted 'Précoce' (Vibert, 1843) at L'Haÿ, as well other mosses (John Cranston, Rotrou, etc... due to heavy negligence). This problem can be also seen in the Loubert's collection. In my opinion, after having diving deeply in archives and old collections, this is more the original 'Précoce' who's gone forever...
you're right, 'Sans Sépales' was mislabelled at L'Haÿ and was strangely replaced by the bengal 'Brennus' (Laffay, 1830). This mistake is still present at L'Haÿ and in the Loubert's collection.
