[1] Myrtillocactus geometrizans is a large shrubby cactus growing to 4–5 m tall, with candelabra-like branching on mature plants.

The fruit is an edible dark purple berry 1–2 cm diameter, superficially resembling Vaccinium myrtillus (bilberry or whortleberry) fruit; both the scientific and English names derive from this resemblance.

[2] It is a popular species in cultivation, where young plants commonly remain unbranched for many years.

[4] Fukurokuryuzinboku, roughly translates to fortune (fuku), fief/happy (roku), dragon (ryu), Shinto god/spirit (jin), tree (boku).

[5] It was named after Fukurokuju and Ryujin, two of the Seven Lucky Gods in Japanese mythology.
