Siphocampylus foliosus Grisebach (1874: 201) .

Lectotype (designated here):—[ARGENTINA] Cordoba, in montanis pr. S. Bartolo [February 1871, P. G. Lorentz 121] (GOET 008974! , isolectotypes: CORD 00006338!, W 15316!) .

═ Siphocampylus foliosus var. minor Zahlbruckner (1898: 189) .

Lectotype (designated here):— ARGENTINA. Prov. Cordoba: al Sud de la Cuesta de Copina, Sierra Achala [28 March 1881] legit Galander s/n (W 1897-0004960! , isolectotypes: CORD 00005198!, CORD 00005199!).

Note: — The Argentinian material collected by Professor P. G. Lorentz and published in Grisebach (1874), which includes the description of S. foliosus, were deposited by the collector at CORD, GOET, and W. As lectotype for S. foliosus, we selected the specimen deposited at GOET since it is likely the original material that Grisebach examined.

We examined original material of S. foliosus var. Minor available at W (W 1897-0004960) and CORD (CORD 00005198, CORD 00005199). We selected the W material as lectotype since this is Zahlbruckner’s primary institution, matches the protologue, and is a well-preserved specimen with numerous flowers and fruits. Assigning isolectotypes was more difficult because there is no collection number and there are two distinct dates listed on the CORD specimens: “ 29 III 1881 ” (CORD 00005198) and “ 28 III 1881 ” (CORD 00005199). Because this latter matches the W specimen, we consider it an isolectotype.
