The Boojum tree is a plant with a restricted (and thus endemic) distribution in the peninsula of Baja California, a small portion of Puerto Libertad (Sierra Blanca) in Sonora and Ángel de la Guarda Island. However, the greatest density area is right in the middle of the peninsula, from the south part of El Rosario, Baja California to the northern slopes of the Tres Vírgenes volcano, in Baja California Sur. This arid region has an average of 73 to 140 mm of annual rainfall, mainly from January to April and less rainfall between August and September. Miguel del Barco (León-Portilla, 1988) referred to this plant as “a type of fleshy vegetable, a tree that is not found in another part of America or elsewhere in the world, not even in California.” The Boojum tree is part of a type of vegetation called sarcocaulescente (Succulent stems), and it is associated with the following species of plants: Baja elephant tree (pachycormus discolor), Mexican giant cardon (Pachycereus pringlei), ocotillo (Fouquieria splendens), Adam´s tree (Fouquieria diguetii), datilillo (Yucca valida), creosote bush (Larrea tridentata) and a wide variety of cactuses and agaves. In addition, this species is associated with an epiphytic plant called ball moss (Tillandsia recurvata) and hanging lichens such as the Ramalina menziesii (Lace Lichen), mainly in areas near the Pacific coast populations that present high humidity.
