Taxonomie : D'après Borges
et al. (
2022): "Contrary to Grimes (1993), who recognised
Pseudopiptadenia psilostachya and
Ps. suaveolens as distinct species, we agree with Lewis and Lima (1991) on the synonymisation of
Ps. suaveolens under
M. psilostachya. These plants grow sympatrically and the traits used by Grimes (1993) to support recognition of two species are too variable to be diagnostic."
