Notes

Recognisable by the symmetrical, acute leaf base and the erect pubescence on the lower leaf surface and veins. The plants have a strong peppery smell (according to T. van Andel, pers. comm.).
The collection French Guiana, Wachenheim 168 in Paris bears a type label. Although Trelease mentioned this collection together with Sandwith 231 in his protologue, he designated the latter as the type. The Paris collection thus is a paratype.
The Sagot 844 specimens in NY and P belong to Piper wachenheimii, this in contrast to the B specimen on which C. de Candolle based his P. rubescens; see also note to P. demeraranum.
