Unresolved, invalid or simply misspelled names – part 1

There are some scientific names, sometimes appearing in listings etc., which seem to lead to nowhere, in some cases these can be assigned to plants which were obviously described by someone under these respective names.

Two examples are given here.:

Ceropegia bemarahaica M. G. Gilbert – described from the Tsingy de Bemaraha Strict Nature Reserve in the Antsalova District / Melaky Region in the east of Madagascar.

Ceropegia brachyantha M. G. Gilbert – described (by the same author) from the Manongarivo Massif in the Ambanja District / Diana Region in the north of Madagascar.

Both names are unresolved, no one seems to know anything about these two enigmatic ‘species’.
