Botanical Data

Plant Notes: Planta parasita ubicado a 15 metros de altura, sobre un arbol de 25 metros de altura. Inflorescencia axilar y caulinares. Updated note from Dr. Job Kuijt, May 15, 2012: "I don't know how I missed that one, but it is by far the most interesting of that set. It is Phoradendron rusbyi Britton, a hyperparasite on other mistletoes. Did you note the primary host? The curious thing is that Britton (1900) described it as the inflorescence of Phoradendron crassifolium, not realizing it was a hyperparasite on that species. Your collection represents only the third known collection of the species! Very exciting. The type is from Bolivia (La Paz), and the only other collection until yours was from Cajamarca: Santa Rosa, Woytkowski 5740b, at the Smithsonian (US). Your plant is splendid!"
