    When hiking in the mountains near to Santiago, in Chile, you will see red flowers parasiting the cactuses. Called tristerix aphyllus (https://en.wikipedia.org/wiki/Tristerix_aphyllus), these flowers are on the top of the cactuses, some meters above the ground. How do they arrive there? A beautiful video from the BBC with the voice of David Attenborough explains it:

It should not be confused with the mistletoe cactus, which is an epiphytic cactus, and not a mistletoe. Description The mistletoe, Tristerix aphyllus, parasitizes two species of cactus, Echinopsis chiloensis and Eulychnia acida, and in its adult form shows only its flowers and its fruits, bursting forth spectacularly from the columnar cacti which are its hosts. Mauseth (2011) discusses the morphological/anatomical effects of T. aphyllus on the cactus Echinopsis chiloensis. Taxonomy T. aphyllus was first described by John Miers in 1830 as Loranthus aphyllus but with the publication in 1973 of an article by Barlow & Wiens, became Tristerix aphyllus (author, Tieghem (Tiegh.)). Other synonyms are: Loranthus cactorum Hook. & Arn. Bot. Beechey Voy. 25. 1830...
