Etymology -A monotypic genus raised by Britton and Rose in 1909 to honour Alwin Berger, for many years the curator at the garden of Sir Thomas Hanbury at La Mortola in Italy and an authority on Cactaceae.Bergerocactus is a genus comprised of a single species - B. emoryi. This species is prolific along the coast of Baja California and does occur in a small population in extreme Southern California and adjacent islands. This species forms clumps of slender stems just over 2 feet (60cm) in height. It is covered in golden-yellow spines that glow in the sunlight and almost completely cover the stem underneath and vary in length up to two inches. Flowers are a waxy yellow on stout, spiny floral tubes which later form rounded, dry fruits.
In cultivation, this species is seldom grown and is therefore a rare sight to most everyone except those who live in Baja California where it helps define the coastline.
