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)
Distribution & Occurrence
This species exists on salt clay and gypsum soils derived from the Chinle, Cutler and Summerville formations at elevations between 4,400 and 6,000 feet elevation.
Communities where this species is found include mixed desert scrub, juniper, or wild buckwheat-Mormon tea. (Arizona Ecological Services 2002)
|There are four known locations in Utah (Grand, Emery, Kane and Garfield Counties) and one population in Coconino County, Arizona. (Arizona Ecological Services 2002).|
Conservation, Ecology & Research
Sexual reproduction does not seem to be an important reproduction strategy, and pollinators are rarely seen to visit this species.
Mining and tar sands development
Mountain bike and off-road vehicle use
One population threatened by natural erosion
Determine if the variety jonesii should be categorized as a separate species.
ORV use and other threats must be monitored.
