Maas, P. J. M., Westra, L. Y. T., Guerrero, S. Arias, Lobão, A. Q., Scharf, U., Zamora, N. A. & Erkens, R. H. J., 2015, Confronting a morphological nightmare: revision of the Neotropical genus Guatteria (Annonaceae), Blumea 60 (1), pp. 1-219 : 189

1. Guatteria decandra Ruiz & Pav. ex G. Don (1831) 100; R.E.Fr. (1939) 536

This species was described by G.Don as follows: “leaves oblong, acuminated, smooth except the nerves; peduncles lateral; flowers decandrous. S. Native of Peru. Uvària decándra, Ruiz. et Pav. MSS. in herb. Lamb. (v.s.)”. “ Decandrous Guatteria . Shrub.”

Thus far no material of this species could be traced, although we tried BM, CGE, M and OXF. As there are no species of Guatteria known at all with such a low number of stamens, we doubt if this species belongs in Guatteria .
