The genera name from Greek rhaphis; 'beet-root' and akme; 'sharpness' possibly referring to the taste of the roots - haven't tried yet. The species name from velvety or velutinous, covered in dense soft short hairs. *)Accordantly to the latest taxonomic system; APG IV 2016, Asclepiadaceae is now part of the Apocynaceae.
