Greek pseudo– ‘false, looking like’ + udonis. For the similarity to Opuntia udonis.
Presumably originally spelled pseudoudonis (publication not seen). The spelling pseudo-udonis that is sometimes used is contrary to article 60.11 of the International Code of Nomenclature. Adding a diaeresis (ü) is allowed under article 60.7.
