Comments. Although similar looking to Espostoa they are not thought to be related as they come from a different part of south america.
Espostoopsis is a monotypic genus meaning species dybowskii is the only species in the genus.
Stems branch only from the base and start growing a cephalium when about 1.5–2.0 meters tall.
