Stenanthium leimanthoides (Melanthiaceae) and Nestronia umbellula (Santalaceae) in Alabama.

摘要

Habitats of Stenanthium leimanthoides [Stenanthium densum] range from Atlantic white cedar and bay swamps in Georgia and Florida, to cutover shrub bogs and seepage slopes in other southeastern states, including Alabama. While conducting fieldwork in late May of 2008 in the coastal plain of southeastern Alabama (frequently referred to as the Wiregrass region), a new population of S. leimanthoides was discovered. It is listed as an S1 taxon by the Alabama Natural Heritage Program (2011) in Auburn. Indian olive, Nestronia umbellula, is a colonial, dioecious shrub that is hemiparasitic on the roots of other plants, often in association with pines. Habitats for Indian olive range from dry to moist forests associated with oaks in the Piedmont to the ecotones between sandy uplands and bay swamps in the inner Atlantic and Gulf Coastal Plains. Indian olive has an S2 ranking in Alabama where it is considered imperiled due to rarity by the Alabama Natural Heritage Program (2011). The distribution and ecology of S. leimanthoides and N. umbellula in Alabama are also discussed.Digital Object Identifier http://dx.doi.org/10.2179/12-016
