Note
Moquin-Tandon (1849b) used two specimens collected by Ruiz & Pavón when describing Tandonia diffusa (cited as "v.s. in h. Webb. et Maire"). Hauman (1925) designated the material in P as type ("le type: herb. Paris"). There are two specimens of this collection in P-Moq., but only one of them ("Maire") was cited in the original description and should consequently be regarded as the lectotype. Anredera diffusa is morphologically similar to A. aspera, A. brachystachys, and A. marginata, especially the last mentioned, and the most easily used distinguishing character is the reddish perianth (vs. a whitish one in most other Anredera species). In contrast to the closely related species, the inflorescences of A. diffusa are often, but not always, branched several times above the base. The variation is not fully understood, however, and it may turn out that A. diffusa and A. marginata are better treated as two different subspecies within the same species. The type of the here synonymised Boussingaultia minor has most probably been destroyed. The original description is rather brief, but the statement that the perianth is externally red, and the collection locality in central Peru, indicate that it is conspecific with A. diffusa.
