Arthropodium strictum), commonly known as chocolate lily, is a herbaceous perennial plant species native to Australia.

The species has up to 12 leaves that are linear or lanceolate in shape and are up to 65 cm long and 1–12 mm wide.

[3] The species was formally described in 1810 by Scottish botanist Robert Brown, based on plant material collected at Port Dalrymple in Tasmania.

[7] The name is treated as Dichopogon strictus in the World Checklist of Selected Plant Families and by the National Herbarium of New South Wales, while the name Arthropodium strictum is used in the Northern Territory, Queensland, South Australia, Victoria and Tasmania as well as in the 2006 Australian Plant Census.

In drought conditions, plants may shrivel back to the tuber then resprout with autumn rains, whereas in situations where steady moisture levels are maintained in the soil, the summer flowering period will be extended.
