Combretaceae and Ericaceae

Conocarpus erectus vs Kalmia latifolia

These two are not on this page because a keyword tool suggested them. They are here because our own identification model genuinely mistook one for the other, on real photographs, 3 times. We publish the rate, and then we tell you what actually separates them.

When the plant was The model said How often
Conocarpus erectus Kalmia latifolia 3 of 20 (15%)

The confusion runs one way only. The model mistakes Conocarpus erectus for Kalmia latifolia, but not the reverse.

Measured on 38,949 openly licensed, research-grade photographs. Full method and dataset.

What actually separates themon the record

Family Combretaceae versus Ericaceae. Different families, which is a real separation.
Genus Conocarpus versus Kalmia.
Flowering Peaks in September versus June. If the plant is in flower, timing helps. (n = 110 and 4,068.)

What we do not have yet: the diagnostic morphological character that a botanist would key on, from a source we can cite. We are not going to invent one. Until we have it, this page tells you the two are genuinely confusable, how often, and what the taxonomy and the flowering data do and do not settle.
