Taxonomie : D'après Lachenaud
et al.
2022: "This species closely resembles
Rudgea hostmanniana, and the two have often been regarded as
synonyms in herbaria, although the synonymy seems not to have been officially published. Steyermark (1967: 399) in
his dichotomous key separated them only by the size of the petiole, supposed to be 2–5 mm in
R. hostmanniana and
8–15 mm in
R. cornigera. In fact, the two species must have been inverted in the key, since
R. cornigera has petioles
not exceeding 8 mm in length, usually shorter than those of
R. hostmanniana. A detailed study of the material available
showed that petiole length is not a reliable character to separate the two taxa; however, more significant differences
exist (see Table 1) and
R. cornigera should therefore be maintained as a separate species."
