Natural range of Opuntia humifusa from USDA NRCS Plants Database.

Common names: Devil's-tongue; Eastern prickly pear[1]

Taxonomic notes

Synonyms: Opuntia compressa (Salisbury) J.F. Macbride var. compressa; O. impedita Small; O. macrarthra Gibbes; O. opuntia (Linnaeus) Karten; O. calcicola Wherry; O. rafinesquei Engelmann.[1]

Varieties: none.[1]

Description

A description of Opuntia humifusa is provided in The Flora of North America.

The leaves of Opuntia humifusa are 1.5-6 cm long, with the longest leaves having an acute to acuminate tip. The hairs of the leaf surfaces are similarly long and the leaf sheaths and culm axis are glabrate to pilose with hairs shorter than 1.5 mm. The awns are glabrous and the lemma is 9-11 veined.[1]

The root system of Opuntia humifusa includes stem tubers which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion.[2] Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 159.7 mg/g (ranking 32 out of 100 species studied) and water content of 47.2% (ranking 3 out of 100 species studied).[2]

According to Diaz-Torbio and Putz (2021), Opuntia humifusa has stem tubers with a below-ground to above-ground biomass ratio of 0.606 and nonstructural carbohydrate concentration of 159.7 mg g-1.[3]

Distribution

It is the only cactus to be widespread in the eastern United States.[4] It is mainly restricted to the Appalachian Mountains, in states like Deleware, Maryland, New Jersey, Virginia, and West Virginia, but also occurs in central and northcentral Mississippi. Further surveying could reveal populations in Alabama, northwestern Georgia, western South Carolina, western North Carolina, and northeastern Tennessee.[1]

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.[5]

O. humifusa was unaffected by soil disturbance by backe seeding, high-severity burning, and salvage logging in central Florida sand pine scrub.[6]

It had mixed responses to clearcutting in central Florida. In some cases the plant increased its cover and in other areas it was unaffected by the practice. It has shown regrowth and been unaffected in reestablished native sand pine scrub that was disturbed by clearcutting.[6]

This species increased its cover in response to soil disturbance by single roller chopping and broadcast seeding in central Florida pine scrub habitat. It has shown regrowth in reestablished native habitat that was disturbed by these practices.[6]

Additionally, O. humifusa reduced its frequency and density in response to soil disturbance by roller chopping in northwest Florida sandhills. It has shown resistance to regrowth and been unaffected by reestablished native sandhill habitat that was disturbed by this practice.[7]

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.[8]

Phenology

O. humifusa has been observed flowering April through July with peak inflorescence in May and fruiting January, May, and December.[5][9]

Root stocks and detached cladodes can propagate vegetatively for up to 12 months after detachment.[8]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates.[10] The fruit is eaten and dispersed by birds, rabbits, woodrats, prairie-dogs, mice, ground squirrels, and white-tailed deer.[11]

Seed bank and germination

The germination rate is low.[11] O. humifusa is known to occur in above-ground vegetation and in the fall surveyed seed bank in the southern ridge sandhill regions in south-central Florida.[12]

Fire ecology

O. humifusa will resprout and recruit seedlings during post-fire recovery.[13]

Pollination

Opuntia humifusa has been observed at the Archbold Biological Station to host bees from the Apidae family such as Apis mellifera, Bombus impatiens, B. pennsylvanicus and Mellisodes communis, sweat bees from the Halictidae family such as Agapostemon splendens, Augochlorella aurata, Augochloropsis sumptuosa, Halictus poeyi, Lasioglossum nymphalis, and L. puteulanum, and leafcutting bees from the family Megachilidae such as Dianthidium floridiense, Lithurgus gibbosus, Megachile brevis pseudobrevis and M. policaris.[14] Additionally, O. humifusa has been observed to host sweat bees from the Halictidae family such as Agapostemon virescens, Lasioglossum leucocomum, L. pruinosum and L. semicaeruleum, true bugs such as Myodocha serripes (family Lygaeidae), and leafcutting bugs from the Megachilidae family such as Megachile addenda, Megachile centuncularis and Osmia texana.[15]

Herbivory and toxicology

It is an important food for pocket gophers.[16] It is a host to the invasive cactus moth (Cactoblastis cactorum).[17] The large pads provides nesting to bobwhite quail.[18]

Conservation, cultivation, and restoration

Cultural use

Native Americans used the pads to heal wounds, warts, and drank pad tea for respiratory issues.[4] It was also used as a poultice to stimulate milk supply in nursing mothers. The roots were used to stimulate hair growth and boiled with milk to treat dysentery, and a tea of the flowers could be used for urinary issues. A tea from the stem could be used in treating headaches, eyes problems, and insomnia.[19]
