Triplaris longifolia Huber (1906: 559)

Type (designated by Brandbyge 1986):— PERU. Ucayali [River], Cerro de Canchahuaya , 9 November 1898, J. Huber 1458 (lectotype: RB [ RB 559945 , digital image!]) ; isolectotypes: F [ F 27773 (photonegative), digital image!], G [ G 437670 , digital image!], MG [ MG 1458 , digital image!] ).

Notes:— The lectotype gives the locality “Cerro de Canchahuaya” which is reported by Brandbyge (1986). The G specimen ( G 437670) further specifies this locality including “ Rio Ucayali, Cerro de Canchahuaya”. While we were unable to find a Cerro de Canchahuaya on the Ucayali River, we did locate a Canchahuayo, a small village on the shores of the Ucayali River about 30 km north east of Pampa Hermosa (- 7.038114 N, - 75.095891 W) next to a topographically raised area. The protologue indicates that the type material was collected “nas partes altas do Cerro de Canchahuaya.” These hills near Canchahuayo are the probable type locality.

It is interesting to note that the photonegative at F ( F 27773) claims to be an image of the isolectotype at G. The photo and the G specimen look very similar, yet one of the major leaves is missing from the current G specimen but is present in the F photonegative. It is unclear where this leaf went but it was presumably removed at some point after the taking of the photograph. This is similar to what was seen in the photonegative of Cuming 1108 at F (See Triplaris melaenodendron subsp. colombiana entry below).
