Appearance
"Myrtillocactus geometrizans" is a large shrubby cactus growing to 4–5 m tall, with candelabra-like branching on mature plants. The individual stems are 6–10 cm diameter, with five ribs, with areoles spaced 1.5–3 cm apart. The flowers are creamy white, 2–2.5 cm diameter. The fruit is an edible dark purple berry 1–2 cm diameter, superficially resembling "Vaccinium myrtillus" fruit; both the scientific and English names derive from this resemblance.References:
