Contents
Taxonomic Notes
Varieties: C. compacta var. compacta; C. compacta var. efimbriata[1][2]
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. This species is typically a light green color, but there is considerable variation within the species.[3]
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
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 V. corymbosum in North Carolina[4] and Citrus sinensis in Florida.[5] In Virginia, C. compacta is the only dodder to grow on Alnus serrulata, and has not been recorded parasitizing any monocots.[3]
Phenology
In the southern and mid-Atlantic United States, C. compacta flowers from late July through November.[1][6] 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.[7]
Diseases and parasites
C. compacta is reported to transmit the psorosis virus to 5% of sweet orange (Citrus sinensis) tested.[5]
