I think both Kalanchoe luciae ssp. luciae and K. thyrsiflora are accepted names. (on Kew it is Kalanchoe luciae!)
I found a key on Kew..

K. luciae ssp. luciae is on the Flora of Zimbabwe but the date is 2005..

Kalanchoe luciae subsp. luciae on Tropicos doesn't have a different accepted name but has synonyms ..

Kalanchoe thyrsiflora is mentioned on Kew as a synonym of Kalanchoe luciae, Kalanchoe luciae ssp luciae is also said to be a synonym, but that doesn't mean Kalanchoe thyrsiflora is not also an accepted species, it just means that at some time one was thought to be the other.
