The illustration of Phaeonychium parryoides in FRPS is based on a plant of P. jafrii, but the trichomes were erroneously drawn.

After publication of the family treatment for the Flora of China, this was treated as Solms-laubachia parryoides (Kurz ex Hook. f. & T. Anderson) D. German & Al-Shehbaz (Nordic J. Bot. 28: 650. 2010).
