Common names: Rusty staggerbush; Crooked-wood
Synonym: Xolisma ferruginea (Walter) Heller
The genus Lyonia is named for John Lyon, a 19th century botanist who is best known for his travels in southern Appalachians. The species name is Latin for rust-colored, which refers to the rusty appearance on the abaxial side of the leaf.
A description of Lyonia ferruginea is provided in The Flora of North America.
Populations can be found in south South Carolina, southeast Georgia, and Florida.
Habitats of L. ferruginea in the coastal plain include coastal dunes, titi thickets, longleaf/saw palmetto flatwoods, shrub bogs, live oak scrub sand ridges, and xeric scrubs. It has been found to occur in disturbed areas such as roadsides and powerline corridors. Soil types include sandy loam, loamy sand, peat and white sand. Associated species include Cyrilla, Cliftonia, Rhododendron, Myrica, Lyonia lucida, L. fruticosa, Ilex glabra, Pinus clausa, Quercus chapmanii,, Q. myrtifolia, Ilex ambigua, Serenoa repens, Pinus elliottii, Ilex coriaca, Liquidambar styraciflua, Quercus nigra, Q. incana, Gelsemium sempervirens, Smilax bona-nox, S. pumila, Pteridium aquilinum, and Aristida strict. 
In a study at the Okefenokee Swamp, Schlesinger and Chabot (1977) found L. ferruginea to be the dominate, evergreen shrub in pine forests surrounding the swamp. It was also observed that the rate of water uptake falls behind the transpiration loss at midday.
L. ferruginea occurs in evergreen scrubs that experience a natural fire rotation. Populations occur in the scrubs of Cumberland Island located off the coast of Southern Georgia. These scrubs are pyric disclimaxes and have been found to have a natural fire rotation of 20 to 30 years that are related to coastal drought cycles and the occurrence of dry lightning. 
The following Hymenoptera families and species were observed visiting flowers of Lyonia ferruginea at Archbold Biological Station: 
Apidae: Apis mellifera, Bombus impatiens
Colletidae: Colletes brimleyi, C. productus
Halictidae: Agapostemon splendens, Augochlorella aurata, Augochloropsis sumptuosa
Megachilidae: Megachile xylocopoides
Sphecidae: Oxybelus laetus fulvipes, Stictiella serrata, Tachysphex apicalis
Vespidae: Stenodynerus lineatifrons
Diseases and parasites
Exobasidium ferrugineae is a closely associated disease with L. ferruginea that is characterized by causing hypertrophied flowers. 
It is considered to be a true host of the pest Stephanitis blatchleyi.
