The American Buckleya, a rare shrub of the Santalaceae family, has a very limited distribution (Sutter et al. 1987). Trees and herbs in this family are usually found in the tropics and are often parasitic or semi-parasitic (Harper 1947). Buckleya distichophylla has dioecious flowers and is semi-parasitic on hemlock roots (Musselman 1982). In addition to the American buckleya, a few more Buckleya species exist in China and Japan.
Distribution & Occurrence
- North Carolina
B. distichophylla inhabits mountain woods at river banks (low elevations). Locations with periodic wildfires appear to have the healthiest populations of this species (VANHP 2000).
Eastern Tennessee: the type locality at Paint Rock (near North Carolina line);
|Current populations are unknown.|
Conservation, Ecology & Research
During the 80's, Buckleya was reported to also have association with a number of pines, broad-leaf trees, forbs, grasses, and ferns. It is not known precisely at what stage of development, for how long, and to what degree Buckleya is dependent on its host plant.
The Japanese botanist S. Kusano provided information on Buckleya hosts as early as 1902. According to Kusano, the haustorial connections had been found with species of Cryptomeria, Abies, and Chamaecyparis, as well as 9 genera of dicotyledonous trees and shrubs. He was also able to establish Pinus and Torreya species as Buckleya host plants during his experiments.
Seedlings grown in 1962 in the Arnold Arboretum flourished in their containers without Tsuga or any other host plant. More than 30 were planted in 1963 on Hemlock Hill, in the natural hemlock grove on the grounds, but all perished by the next year.
Lack of frequent fire causing habitat succession
Falling limbs from the upper canopy
Seed propagation: Fordham (Arnold Arboretum) successfully grew seedlings from seeds (over 50% germination after 2 or 3 months of cold stratification at 40F; no germination if started immediately).
