Espostoa lanata (Kunth) Britton and Rose (a.k.a. 'Peruvian Old Man Cactus') is a slow growing tree-shaped cactus branching at the top with age, 1,5 to 7 m tall. Like Cephalocereus senilis (the 'Old Man of Mexico') it is a densely hairy species, covered by a warm woolly coat and well adapted to high altitudes, the main difference is the presence of sharp spines on Espostoa. It is widespread in in habitat and quite variable in size and spines for this reason it has received several names.
