Amblysperma should be retained under Trichocline (Asteraceae, Mutisieae)
Abstract:The monotypic genus Amblysperma has been distinguished from Trichocline by previous authors on the basis of differences in geographic distribution, involucre shape, corolla colour, limb indumentum of the marginal corollas, anther filament surface, type of staminode basal appendages, and achenial shape. However, a critical re-examination of these characters reveals that most of them are shared between both genera. The presence of twin hairs in the corollas of Amblysperma and Trichocline is another character linking both genera. Differences in geographic distribution, i.e., Amblysperma in Australia and Trichocline in South America, and shape of the involucre provided the only distinguishing features which do not appear to justify the recognition of two different genera. Amblysperma is therefore placed in synonymy with Trichocline.
