I went to the MOBOT (Missouri Botanical Gardens) site but I couldn't find anywhere to search for scientific names at their site.
This is copied and pasted from what I see at the Tropicos site but nothing states accepted or not:
Crassulaceae Kalanchoe luciae subsp. montana (Compton) Toelken J. S. African Bot. 44(1): 89 1978
Crassulaceae Kalanchoe luciae subsp. luciae
Crassulaceae Kalanchoe luciae Raym.-Hamet Bull. Herb. Boissier, sér. 2, 8: 256 1908
The Catalogue of Life shows:
Kalanchoe luciae (accepted name)
Kalanchoe luciae subsp. montana (Compton) H.R. Tölken (accepted name)
Kalanchoe montana Compton (synonym)
Kalanchoe luciae subsp. luciae (accepted name)
