Taxonomie : D'après Lachenaud
et al. (Phytotaxa, 531(3):
157. 21/01/2022): "This species closely resembles
Rudgea bremekampiana Steyerm. 1967, from French Guiana and northern Brazil (state of Amapá), and has been previously confused with it in herbaria. Both species have glomerulate inflorescences with a short peduncle, red, ellipsoid fruits, thick, glabrous leaves, and flat stipules (i.e., lacking a dorsal keel) with marginal appendages.
Rudgea bremekampiana differs from
R. approuaguensis by the glabrous stems, conspicuous bracts, and greater dimensions of all its organs (differences are summarised in Table 1)."
