Rhus kearneyi
|
Rhus kearneyi plants are large showy, evergreen shrubs that grow up to three meters in height. The dioecious flowers grow in creamy white clusters and bloom in March. Petioles and young twigs are a striking reddish color. Many species of Rhus can be found in small numbers in the canyons of northern Sonora, Mexico.
Distribution
& Occurrence |
|
State Range
Habitat
| |
Plants are found growing along steep canyons and drainages (relatively few individuals) (Kearney and Peebles 1973). |
Distribution
| |
Rhus kearneyi is known from the Tinajas Altas, Cabeza Prieta, and Gila Mountains of southwestern Arizona, at elevations of 1000 to 1500 feet (Kearney and Peebles 1973). |
Number Left
| |
There is only a single population known in the U.S. from one canyon in the tinajas Altas Mountains on the Barry Goldwater Bombing Range. |

Relationships

Kearney's Sumac needs the protection and shade of deep canyon walls. |
Threats
| |
Because it is inherently rare, this species may be threatened by stochastic events. |
Current Research Summary
| |
Desert Botanical Garden collected seeds of R. kearneyi in 1986. Plants are easily propagated from seeds and cuttings, but do not thrive in containers for longer than a few years. Over fifty plants can be found in ornamental exhibits within the Garden. The Garden has produced thousands of seeds in cultivation on plants grown to reproductive maturity from field-collected seeds. This species is really attractive in cultivation and has potential valuable horticultural contribution to low-water use landscapes. (Desert Botanical Garden 2000) |
Current Management Summary
| |
Although plants are not undergoing any immediate human induced threat, management planning should include seed banking for potential reintroduction in the occurrence of a devastating stochastic event. |
Research Management Needs
| |
This species general biology and ecology would be interesting to know. |
