Kalanchoe luciae subsp. luciae is the autonym of Kalanchoe luciae. You can read about autonyms here:
http://en.wikipedia.org/wiki/A...)
Both of these names are accepted, as well as K. luciae subsp. montana. (see
COL)
If you've keyed your plant to Kalanchoe luciae, but haven't narrowed it down as to subspecies, the photos should go into the
Flapjacks (Kalanchoe luciae) entry as Lin suggests.
PS - Great pics!
