During the June expedition for the Livingston Biodiversity Project, Izabal, we observed Selenicereus testudo, a species of cactus found on the branch of trees. On our third day we had the joy of seeing two flowers of this species. Something that we had not seen in the previous months. According to Véliz in “Las Cactáceas de Guatemala” (2008), the species occurs in Chiquimula, Izabal, Zacapa, Alta Verapaz and Petén. Its flowering is nocturnal and happens between April and October.
The same author also mentions that Guatemala is one of the three entities in the Mesoamerican region with the greatest richness of cacti, the other two are the State of Chiapas, Mexico and Costa Rica. In the Guatemalan territory there are 48 native species plus 4 intraspecific categories.
FLAAR Mesoamerica’s team has documented this species in Parque Nacional Yaxha, Nakum y Naranjo. You can find more information here.
