In May 2018 I had the opportunity to co-organize an independent expedition to the areas surrounding the massif of Ptari-tepui and Sororopan-tepui in Estado Bolívar, Venezuela. My group led by a team of Pemón guides from the community of Santa Teresita de Kavanayen succeeded in reaching the location of the first scientific expeditions to the massif of Ptari-tepui led by W. Phelps in February 1944 and J. A. Steyermark in November 1944, including re-discovering the locus classicus of Heliamphora heterodoxa which had not been accurately located ever since the original publication of the taxon in 1951 (McPherson et al. 2011).
