[1387] Amanoa grandiflora (Müll.Arg.) Müll.Arg.

( Fig. 46A )

Flora 55: 2 (Müller 1872). — Amanoa guianensi s var. grandiflor a Müll.Arg., Prodr. [A. P. de Candolle] 15 (2.2): 910 [late Aug. 1866] (Müller 1866).

Amanoa potamophila Croizat, Amer. Midl. Naturalist 29 (2): 475 [5 Apr. 1943] (Croizat 1943).

Amanoa macrocarpa Cuatrec. , Brittonia 11: 164 (Cuatrecasas 1959).

NOTES. — Hayden (1990) showed that the Aublet collections, which could have served as the type of Amanoa guianensis Aubl. , actually belong to two distinct species. One is known only from a few specimens from French Guiana, Amapá and Suriname; the other is widespread from Central America to northern South America ( Hayden 1990). He therefore selected among these specimens a lectotype (W[W-1889-0012576]; isolectoypes G[not seen], F[V0055866F], A[not seen], MO[not seen]) which corresponds to the current usage of Aublet’s name, that is to the widespread species, and described a new species, Amanoa neglecta W.J.Hayden , based on the second entity found in Aublet collections (holo-, P-JJR[P00777979], iso-, BM[BM000645699]) ( Hayden 1990). This was a laudable choice to preserve the current usage of the name A. guianensis , but unfortunately Hayden (1990) overlooked the previous lectotypification of A. guianensis Aubl. by Lanjouw & Uittien (1940: 148), who designated the P-JJR specimen. Given the anteriority of this lectotypification ( Delprete 2015), there is no choice but to change the name of the most widespread taxon, and to adopt the oldest available name, Amanoa grandiflora (Müll.Arg.) Müll.Arg.
