Taxonomic notes
Description
A description of Opuntia humifusa is provided in The Flora of North America.
Distribution
It is the only cactus to be widespread in the eastern United States [1]. It is found in southern Canada as well as the eastern United States (Goldstein and Nobel 1994).
Ecology
Habitat
Opuntia humifusa can occur in upland longleaf pines, sand dunes, Pinus clausa scrubs, open sand flats, sandhills, and pine/oak scrubs. It has been found in disturbed areas such as loblolly tree farms and roadside depressions. Associated species include Lyonia ferruginea, Lyonia lucida, Serenoa repens, Quercus geminata, Q. chapmanii, Persea humilis, Ceratiola, Osmanthus megacarpus, Rhynchospora megalocarpa, Galactia elliottii, and Smilax auriculata (FSU Herbarium).
It occurs in southern Canada, where average nighttime temperatures can reach -4 degrees Celsius. In order to prevent intracellular freeze dehydration and ice formation, individuals have an accumulation of sugars and mannitol in their cells (Goldstein and Nobel 1994).
Phenology
It has been observed flowering April through July and fruiting January, May and December (FSU Herbarium).
Root stocks and detached cladodes can propagate vegetatively for up to 12 months after detachment (Nobel and Castaneda 1998).
Seed dispersal
The fruit is eaten and dispersed by birds, rabbits, woodrats, prairie-dogs, mice, ground squirrels, and white-tailed deer [2].
Seed bank and germination
Germination rate is low [2].
Fire ecology
Pollination
The following Hymenoptera families and species were observed visiting flowers of Opuntia humifusa at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera, Bombus impatiens, B. pennsylvanicus, Mellisodes communis
Halictidae: Agapostemon splendens, Augochlorella aurata, Augochloropsis sumptuosa, Halictus poeyi, Lasioglossum nymphalis, L. puteulanum
Megachilidae: Dianthidium floridiense, Lithurgus gibbosus, Megachile brevis pseudobrevis, M. policaris
Use by animals
It is an important food for pocket gophers (Myers and Vaughan 1964). It is a host to the invasive cactus moth (Cactoblastis cactorum) (Jezorek and Stiling 2012). The large pads provides nesting to bobwhite quail[3].
Diseases and parasites
Conservation and Management
Cultivation and restoration
Native Americans used the pads to heal wounds, warts, and drank pad tea for respiratory issues [1].
