Rondeletia orthoneura = Rondeletia orthoneura K. Schum. & Krause in Krause, Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie 40: 314-315. 1908. Type Protologue: In Columbia: sine loco, v. Warszewicz 622. Type: Warszewicz s.n. (holotype, B destroyed; photograph at F! negative no. 89, http://ww2.bgbm.org/herbarium/images/FieldMuseum/89.jpg; lectotype, designated here, America merid. Columbia, J. Warszewicz s.n. (KRA 533104!; Fig. 4 ), isolectotype, KRA 533105!).

Remarks.

Because the specimens representing R. orthoneura , collected by Warszewicz and preserved at B, were destroyed during WWII, we designated the specimen of R. orthoneura (in KRA), as the lectotype for the taxon. According to Lorence (2012) and Borhidi (2017), Rondeletia orthoneura is conspecific with Rondeletia inconstans Standl., Publications of the Field Museum of Natural History, Botanical Series 7: 31 (1930). Type: Colombia, Quetame, Pipiral, eastern Andes de Bogotá, alt. 1000-1600 m., July 1897, F.C. Lehmann 8751 (holotype F!) = Arachnothryx reflexa var. inconstans (Standl.) Steyerm. Among numerous type specimens (syntypes) of R. reflexa collected by Hartweg 1052 in Bogota, the one, mounted to the sheet with stamp Herbarium Benthamianum 1854 (K 174038!), is designated here as the lectotype.

Notes.

It is worth noting, that in the KRA herbarium there are several sheets with specimens (duplicates of specimens destroyed in B) named by J. Klotzsch but never described (nomina nuda). These include Rondeletia ferruginea Klotzsch (https://fm-digital-assets.fieldmuseum.org/21/689/26.jpg; KRA 533668!), Ladenbergia warscewicziana Klotzsch (https://fm-digital-assets.fieldmuseum.org/21/557/133.jpg; KRA 533185-533197! [13 sheets]), and Rustia warscewicziana Klotzsch (https://fm-digital-assets.fieldmuseum.org/21/532/11.jpg, KRA 533663-533667! [5 sheets]). The latter taxon was identified, based on Macbride photographs, as Rustia thibaudioides (H. Karst.) Delprete by Delprete (1999). The other taxa require further studies.
