Type
Type: Brazil, “Rio Janeiro”, Langsdorff s.n. (holotype P03560903!).
Distribution
Ipomoea langsdorffii is an infrequently collected species from the cerrados of central Brazil with confirmed records only from Minas Gerais — we would regard the cited location of Rio de Janeiro given by Langsdorff as unlikely. Few specimens of this species were cited by O’Donell (1953) and not all specimens listed in the Reflora virtual herbarium (www.herbariovirtualreflora.jbrj.gov.br/) are correctly named so this species is illustrated and all specimens we have seen are cited below:
Note
Ipomoea langsdorffii is a densely hirsute, usually trailing herb. The leaves are distinctly petiolate and typically oblong-elliptic. The usually compact, pedunculate axillary cymes with persistent linear bracteoles 12 – 15 mm in length are distinctive. Unlike I. guaranitica Chodat & Hassl., the cymes are usually 3-flowered and with distinct pedicels, the bracteoles distant from the calyx. A further issue needs to be dealt with as the result of the assertion in Austin et al. (2015: 628) that Ipomoea elegans A. Dietr., as opposed to I. elegans Meisn., is a synonym of I. patula Choisy. As I. elegans A. Dietr. antedates I. patula by almost ten years it would appear that it should be instated as the correct name for the plant treated above as I. langsdorffii. We do not believe this to be the case. Dietrich (1836) diagnosed I. elegans as “foliis inferioribus, quinquelobis, superioribus palmatim-septemlobis utrinque subhirtis scabriusculis, lobis lanceolatis, obtusis …” None of these statements fit I. langsdorffii, which has simple hirsute leaves. As Dietrich mentions that the plant has been in cultivation for a long time, it seems most likely that I. elegans A. Dietr. is the earlier I. platensis Ker-Gawl, also described from cultivated material, or just possibly I. gigantea Silva Manso or I. malvaeoides Meisn.
