Notes

In a personal communication, Callejas informed me that in the Western range of the species the fruits can be densely pubescent.
Trelease & Yuncker (1950: 227) mention in synonymy of P. divaricatum: "? Piper praemorsum Rottb. ex Vahl". This was validly published in Eclog. Amer. 1: 4. 1797. No type is known for P. praemorsum; according to Rottbøll, it was collected in Suriname by Rolander. If this species really would appear to be a synonym of P. divaricatum, P. praemorsum would have to replace P. divaricatum.
