Description
C. compacta is a parasitic dioecious perennial that grows as a forb/herb or a vine.[2] Stems are more than 2 mm in diameter, yellow-green, and form rope-like masses. Although this species is typically a light green color, there is considerable variation within the species. Its inflorescence is a glomerule of 3-5 tubular flowers 5 mm long and 2 mm wide. Seeds are 2-2.6 mm long, brown when fresh, scurfy, globose, ovate to angled or flattened, and oblong.[3][4]
Distribution
C. compacta occurs from Nebraska, south to Texas, eastward to central peninsular Florida, and northward to Illinois, New York, and New Hampshire.[1][2] It has also been introduced in Quebec Canada.[2]
Ecology
Species in the Cuscuta genus are parasitic, growing on hosts for nutrition.[1]
Habitat
C. compacta is found on herbaceous and woody hosts in bottomland forests, stream banks, marshes, swamps, pine savannahs, wet fields, and other wet habitats.[1][3] This species has been reported parasitizing a wide range of species[3], including Vaccinium ashei and Vaccinium corymbosum in North Carolina[5] and Citrus sinensis in Florida.[6] In Virginia, C. compacta is the only dodder to grow on Alnus serrulata, and has not been recorded parasitizing any monocots. Other frequent hosts in Virginia include species of Acer, Liquidambar, Rubus, Rhus, and Aralia.[3] In Florida, Georgia, and Alabama, it has been observed on Ilex glabra and Myrica cerifera along an ecotone between woodlands and a cypress swamp, a shaded sandy loam, on Lyonia and Illicium on an upper slope, along a dam embankment, on Cliftonia monophylla in a disturbed area, on Sambucus in a border of a swampy area, on sandrock banks, and a moist roadside depression.[7]
Phenology
In the southern and mid-Atlantic United States, C. compacta has been observed to flower from late July through November.[1][8] Flowering in Virginia occurs from August 15th to September 28th.[3]
Seed bank and germination
In Virginia, C. compacta has a very high percentage of seed set. Germination occurs best at temperatures of 22-23 °C.[3]
Pollination
While other species of Cuscuta are well adapted for insect pollination, C. compacta is well developed for autogamy.[3]
Use by animals
Pawnee Indians would use C. compacta to dye materials, such as feathers, orange. Maidens of the Pawnee would also use the parasite for divination to determine if their suitors sincerely loved them. A Mexican Indian has reported that rattlesnakes would take this plant into their dens for food.[9]
Diseases and parasites
C. compacta is reported to transmit the psorosis virus to 5% of sweet orange (Citrus sinensis) tested.[6]
Conservation and Management
C. compacta is listed as presumed extirpated by the Ohio Department of Natural Resources. Species in the Cuscuta genus are considered to be a noxious weed in the following states: Alabama, Arizona, Arkansas, California, Florida, Massachusetts, Michigan, Minnesota, North Carolina, Oregon, South Carolina, South Dakota, and Vermont; it is even prohibited or quarantined in some of these states. Of these, most exclude native or widely distributed species.[2]
