Weinmannia cochensis Hieron. View in CoL , Bot. Jahrb. Syst. 21 (3): 310. 1895.

Type.

Colombia • “ Páramo dicta ad fluvium Rio de Cocha , … in regione suprema silvarum, alt. s. m. 3200 m, mense Augusto fructifera collecta est. ” A. Stübel 357 (lectotype, designated here, B [barcode B_10_9009851 !]) .

Note.

In the protologue, Hieronymus (1895) cited five Alfons Stübel collections from Colombia, considered as syntypes: “ crescit ad Cuchilla de Santo Domingo inter urbem Popayan et altiplanitiem Páramo de Huila (coll. columb. n. 290 " [B barcode B _ 10 _ 9009849!, F barcode F 0063217 F image! fragment]; " in altiplanitie Páramo dicta ad fluvium Rio de Cocha, … " (coll. columb. n. 354 [B barcode B _ 10 _ 9009852!]), " et haud procul a loco ultimo indicato in regione suprema silvarum, alt. s. m. 3200 m, … " (coll. columb. n. 357 et 360 d [B barcode B _ 10 _ 9009850!]); " prope lacum Laguna de Pasto alt. s. m. 2800 m " (coll. columb. n. 365 [B!]. ” Bernardi (1961: 179) cited two of those collections at Herbarium B (Stübel 290, 357), but did not designate a type, and Harling (1999: 39) cited all five aforementioned collections as syntypes, but he was unable to study any of them. The specimen here chosen as lectotype, A. Stübel 357, deposited in the Berlin Herbarium, matches the original description well and has inflorescences; furthermore, the area where it was collected can be easily discerned today based on the label information: “ Excursión de Pasto a la Laguna Grande de Cocha y al Cerro Patascoy (falso): región superior de bosques, 3200 m, viii, 1869. ” The specific epithet refers to ‘ Laguna de la Cocha’ in Nariño, Colombia. The other syntypes have rather imprecise label localities, lack inflorescences, or are fragments only. This species is accepted in Bernal (2016: 1126) and Harling (1999: 22).
