Etymology The former genus name Trientalis is derived from the Latin ('a third'), and is an allusion to the height of the plant, which is one third of a foot, or high. Latifolia is derived from the Latin words ('broad or wide') and ('leaves') and means approximately 'broad-leaved'. The alternative name "Indian potato" refers to a small subterranean swelling at the stem's base, which is not listed as being edible by modern sources.
