Xylopia parvifolia (Wight) Hook.f. & Thomson (Annonaceae), based on Patonia parvifolia Wight, is a tree species native to Sri Lanka and India. Unfortunately the widely used name is an illegitimate later homonym. Xylopia patoniae I.M.Turner is here proposed as an avowed substitute. There have been two proposals to lectotypify Patonia Wight. The earliest, and one to be followed, proposed Patonia parvifolia Wight as the lectotype, maintaining Patonia as a synonym of Xylopia. A later proposal to make Patonia walkeri Wight (≡ Diospyros walkeri (Wight) Gürke) the type has to be disregarded.
