Gaylussacia brachycera
|
The box huckleberry is a dwarf (1-4 dm) evergreen shrub that forms large, solid-mat, self-sterile colonies, each one appearing to consist of a single clone that may extend over 8 acres! One colony in Perry county Pennsylvania (the Amity-Hall area) is about a mile long. It appears to be a single clone that is over 12,000 years old, and has been labeled as the oldest living thing in the world. As of 1999, about other 100 sites, containing younger plants than the Perry County population, are known from six states in the eastern United States.
Box huckleberry is a rare plant first found by Michaux in West Virginia in 1790, then by Kin and Pursh about 1805 (Coville 1919). In 1921, it was "rediscovered" by A. Gray and this time reported from 75 localities (Gray 1922). The box huckleberry belongs to a rather large genus of the New World embracing over 50 species, most of which occur in mountainous regions of South America. Five are found in the southeastern USA. All Gaylussacia are small shrubs (1-12 dm tall), either evergreen or deciduous, usually with rhizomes (Dirr 1998).
G. brachycera is very different from other Gaylussacia species. In other Gaylussacia, leaves are deciduous, mostly entire, glandular, either on both surfaces or just beneath (which makes a difference from Vaccinium); stems not angled (Dirr 1998). In G. brachycera, leaves are evergreen, coriaceous, not resinous-glandular; stems are sharply angled (3-sided), bearing a conspicuous ridge below the base of each leaf.

Habitat
| |
G. brachycera can be found on wooded slopes, mostly facing north and on acid, well-drained (sandy) soil (Gray 1922,Small 1933, Tatnall 1946, Foote and Jones 1994). |
Distribution
| |
G. brachycera is known from West Virginia and possibly Virginia. It has also been found in Pennsylvania, the ,coastal plain of Delaware, Kentucky and Tennessee (Gray 1922, Small 1933, Gleason 1952, Tatnall 1946, Foote and Jones 1994). |

Relationships

Honeybees are attracted to the flowers of this species, and are likely the primary pollinators. This species is probable an obligate outcrosser, requiring pollinators of some sort to transfer pollen from one individual to another. This is especially difficult for this plant, as populations can be extremely large, but are often a single clone. (Crable 1999) |
Threats
| |
Irresponsible development at coastal habitats; recreation; human Trampling
Erosion after logging
Overtopping by arboreal species or fast growing herbs or vines; Invasive species
Habitats vanish due to natural plant succession |
Current Research Summary
| |
There is no current research. |
Current Management Summary
| |
A formal management plan has not be designed. |
Research Management Needs
| |
Remaining populations need to be identified and monitored. Many aspects of this species biology and ecology need to be studied. Including reproductive biology and other plant and animal interactions, such as seed dispersal and herbivory. |
Ex Situ Needs
| |
Box huckleberry appears to grow successfully under rhododendrons and mountain laurels, in partial shade.
Propagation from softwood cuttings: May-July, in sand-perlite 50/50, treated with 2,500-5,000 ppm K-IBA (rooting rate 60-80%). Hardwood cuttings are less successful.
Seed coll. mid-August; cleaned, one month warm followed by two months cold stratification. The germination rate is about 80%.
