REMARKS

Chermezon (1936) cited two Trochain collections in the protologue of Pycreus fallaciosus , both from [bord du] Marigot de Mansadella (N. de Dienoudiella) [ Senegal], May 1934, Trochain 3538 and 3545. Both collections are kept in P, where the Trochain herbarium and types are located ( Stafleu & Cowan 1976 -1988). Duplicates are deposited in BR. Trochain 3545 represents a complete specimen with roots, flowers and fruits, whereas Trochain 3538 only bears three stems (no roots), two of them in flower/fruit, a third with a young inflorescence that hardly emerges from the upper leaf sheath. Both collections were seen by J. Raynal in June 1970 who included this species in P. flavescens (L.) P. Beauv. ex Reich.

Trochain 3545 is the most representative out of the two syntypes and it was already annotated (informally) as lectotype for this name, possibly by J. Raynal. It is here designated as lectotype.
