Botanical Garden Jena / Thuringia / Germany

There appear to be only two species present in that garden, Ceropegia cimiciodora, a very large specimen that grows more or less freely within the surrounding Vegetation (it has already reached a height of about 2 m so far and still grows on).:

The second one is the usual Ceropegia linearis ssp. woodii, however, in this case it is at least a plant of the ‘debilis‘ form (it seems to be there unintended as it is not labelled at all).:
