| This federally threatened species is threatened by off-road vehicle activity, as well as the presence of mining claims and oil and gas leases on or adjacent to known locations of this plant. (State of Utah Natural Resources 2002) Jones' cycladenia is a long-lived perennial herb that grows to only 10-15 cm (4-6 in) tall. Though tiny, it produces beautiful pinkish-rose flowers from mid-April to early June. Leaves are round and somewhat succulent. This species is well adapted to its habitat of mixed desert shrubs by overwintering as belowground rhizomes (roots). (Arizona Ecological Services 2002; State of Utah Natural Resources 2002)
