Remarks.

The genus Cavendishia comprises more than 100 species of neotropical shrubs, having bright, snowy flowers, usually enlarged floral bracts, and alternately unequal filaments and anthers. The genus occurs mostly in the mountains of the north-western part of South America, especially in Colombia. Most species representing the genus Cavendishia are narrow endemics, and only a few of them are widespread ( Luteyn 1983). One of the widespread species is C. bracteata , which appears to be a morphologically extremely variable taxon. Luteyn (1983) listed a number of species which are suspected to be conspecific with C. bracteata . One of them is Proclesia veraguensis described by Klotzsch (1851). Because Klotzsch did not mention either the collection number or the place of preservation of the holotype, and the possibility that the original material of that taxon was destroyed during WWII, Luteyn (1983: 140) designated a photograph of original specimens (in ACS neg. 13 and F neg. 4682) as a lectotype of the taxon. However, bearing in mind, that according to Art. 9.10 of the ICN ( Turland et al. 2018) such photographs cannot be chosen as lectotypes thus it is here corrected to a neotype of Proclesia veraguensis .

In the KRA herbarium, there are three sheets with specimens of Cavendishia collected by Warszewicz (America merid. Columbia, J. Warszewicz s.n., KRA 533506, KRA 533507, KRA 533508), however, identifying whether they are conspecific with Proclesia veraguensis or not, requires further studies.
