Anisotome latifolia is a member of the carrot family and they are only found in New Zealand’s subantarctic, including Auckland, Campbell, Antipodes, Snares and Macquarie Islands. It occurs from the coast up to the tops of the island ranges on the peaty ground between tussocks and other megaherbs, though more rarely under low forest. It is most abundant at lower altitudes and where the vegetation is not subject to browsing by introduced animals.
Anisotome latifolia is a large and robust perennial herb, growing up to 2 m in height. 
The hairless, leathery basal leaves are 300–600 mm long and 100–200 mm wide, 2-pinnate with 5-7 pairs of dark to yellow-green leaflets. The margins are toothed.
The inflorescence axis grows up to 2 m, with a 10–15 mm diameter at the first node. The flowers vary from off-white to a creamy pink in colour. The plant flowers from October to February and fruits from January to March.
One of Anisotome latifolia main pollinators is the nocturnal Sub Antarctic weta (Notoplectron campbellensis).
