Clemensiella

Clemensiella is a species of plants in the Apocynaceae first described as a genus in 1915. It was initially named Clemensia, but this turned out to be an illegitimate homonym (in other words, someone else had already used the name for a different plant), so another name was chosen for this genus. Clemensiella contains only one known species, Clemensiella mariae, endemic to the Philippines.
