Piper motuoense, a new species of Piperaceae from Xizang, China

“…This genus was established, based on the species P. nigrum L. from India ( Sen and Rengaian 2022 ). The genus is considered to comprise approximately 2,000 species, mainly distributed in the Tropics ( Gentry 1982 ; Kubitzki et al 1993 ; Marquis 2004 ; Quijano-Abril et al 2014 ; Jaramillo et al 2023 ; Suwanphakdee et al 2023 ). Distinctive characteristics of Piper include swollen stem nodes and minute, usually unisexual flowers compacted together on a fleshy rachis in Asian Piper species.…”
