Triplaris peruviana Fisch. & C.A.Mey. ex C.A.Mey. (1840: 149)

Type (designated by Brandbyge 1986):— PERU. [Tarapoto, 1835] (fr), Mathews 1620 (lectotype: K; isolectotypes: BM [ BM 993259 , digital image!], E [ E 319858 , digital image!], F [ F 43602 (fragment), F 77063 (Fragment), digital image!], G [ G 437666 , digital image!], NY [ NY 324208 , digital image!], OXF [ OXF 190622 , digital image!], P [ P 734730 , P 734731 , digital image!]) .

Notes:— The protologue only reports “in Peru ” and the collector (“ Mathews ”). Among all of the specimens viewed (herbaria BM, E, F, G, K, NY, OXF, and P), the date 1835 comes from the G specimen ( G 437666). The NY specimen ( NY 324208) contains additional locality information “Tarapote”, which Brandbyge (1986) interpreted as “Tarapoto”. Triplaris peruviana has been collected at Tarapoto in Peru in the second half of the 20 th Century ( Brandbyge 1986). Thus, we follow that interpretation here. Additionally, it appears that all collections of this species have been made in the Rio Huallaga valley ( Brandbyge 1986).

There are some orthological variants of the type collector. In some cases, the name is spelled “Mathews” (e.g., Meyer [1840: 149] and Brandbyge [1986]) and in others “Matthews” (e.g., OXF collection). The collector is Alexander Mathews (d. 1841) and the other spellings should be considered mistakes.
