Taxonomic notes.

L.G. Genevier (1868: 192) wrongly reported this species as R. pyramidatus P.J. Müll. in the Mém. Soc. Acad. Maine Loire. Later, L.G. Genevier corrected the error and proposed a replacement name R. pycnanthus .

R. loirensis is similar to R. anadenes P.J. Müll. ex Genev., the differences being: the former has petals wider, the stamens exceeding the styles and erect peduncles. It is also similar to R. atrocaulis P.J. Müll., the differences being: the former petals white and it is different from R. stereacanthos P.J. Müll. ex Genev. by its narrow panicles.
