NOTES. — A species known only from French Guiana. G. megantha A.Juss. was treated by Pennington & Clarkson (2013) as a synonym of G. grandifolia DC. , but the latter is illegitimate because Candolle (1824: 62) cited Melia guara Jacq. in synonymy. G. megantha is the earliest legitimate name for this species. G. grandifolia is based on two distinct elements: 1) a specimen from French Guiana in G-DC (“ in Guianâ Gallica ”) and 2) fruits of Melia guara Jacq. from Cuba [synonym of Trichilia guara (Jacq.) L. and of G. trichilioides L., nom. illeg. superfl.] Candolle (1824) did not see the material of the latter, and copied Jacquin’s description of the fruit of Melia guara . Although illegitimate, G. trichilioides is the type of the conserved Guarea F.Allem. (not “F.Allem. ex L.”, see Wiersema et al. 2018), and a synonym of G. guidonia (L.) Sleumer. Guarea grandiflora Steud. is actually an erroneous spelling of G. grandifolia . The entry in Steudel (1840: 709) reads “ grandiflora Dec. trichilioides ”, but under trichilioides , it appears as “ G. grandifolia Dec. 1”. “Dec.” stands for A. P. de Candolle, and G. grandifolia is the first entry in Candolle’s treatment of Guarea .
