sites. Recently burned medium sites had much higher net photosynthesis than unburned medium sites. The highest rate of photosynthesis occurred at the burned medium and high sites (Freeman et al 2004). We found that recent prescribed burning, a management tool used to promote the growth of longleaf pine in this ecosystem, elevated levels of net photosynthesis for both ground cover species that we examined as stress indicators. In species with underground perennating organs, burning has been shown to stimulate rates of net photosynthesis (Freeman et al 2004). Although a flush of nutrients immediately follows burning, with an increase in mineralized nitrogen potentially persisting for up to a year (Freeman et al 2004), most of the increase in net photosynthesis is believed to be the result of a change in the ratio of roots to shoots. The new smaller shoots have a proportionately larger root system that provides ample water and nutrients (Freeman et al 2004).

Natural range of Ipomoea pandurata from USDA NRCS Plants Database.

Common names: man-of-the-earth, wild sweet potato, manroot[1]

Taxonomic notes

Synonyms: none[1]

Varieties: Ipomoea pandurata var. pandurata; I. pandurata var. rubescens Choisy[1]

Description

Ipomoea pandurata is a perennial trailing vine, with heart-shaped leaves, has a large storage root, and makes a new shoot every year.[2] The storage root can exceed 20 kg and can be cooked and eaten.[3] This species thrives in canopy opening and in thickets.[2]

Herbaceous annual or perennial vines, or rarely a shrubby perennial. Flowers axillary, solitary, or in 2-5 flowered cymes. Calyx lobes 5, often imbricate; corolla campanulate to funnel-form, or salverform in 2 species; stamens 5, inserted in the corolla tube alternate with the lobes; stigma globose, entire or slightly lobed, style 1, ovary 2-or-4 locular. Capsule 2-4 valved; seeds 2-6, sometimes villous. A large genus of primarily tropical plants, some of which were introduced as horticultural plants and have escaped to become noxious weeds.[4]

Trailing, glabrate, or weakly pubescent perennial from an enlarged root. Leaves ovate, entire or pandurate, 3.5-8 cm long, 2.5-8 cm wide, cordate, often pubescent beneath. Peduncles 1-5 flowered; pedicel glabrous, stout; calyx lobes coriaceous, oblong-elliptic, 12-15 mm long, glabrous, strongly imbricate; corolla campanulate, 6-8 cm long, about as broad, the limb white, the tube lavender within; anthers 5-7 mm long, stamens and stigma included. Capsule ovoid, ca. 1 cm long; seeds villous on the angles.[4]

Distribution

This plant is found north in Connecticut, New York, and southern Ontario, west in Ohio, southern, Mississippi, and Kansas, then south in central peninsular Florida and east Texas.[1]

Ecology

It was observed that I. pandurata’s growth in recently-burned areas is low. However, in areas that are unburned and have low disturbance, it exhibits higher growth rates.[2]

Habitat

Ipomoea pandurata grows in well-drained uplands, sandhills, and open pine-oak scrub.[5][1] It is also observed to grow in disturbed areas, such as roadsides and open fields.[5] A study exploring longleaf pine patch dynamics found I. pandurata to be most strongly represented within longleaf pine gaps and under patches of longleaf that are up to 50 years of age.[6]

I. pandurata was found to be a decreaser in its long-term response following cessation of repeated soil disturbance.[7]

Phenology

I. pandurata has been observed to flower from May to September with peak inflorescence in May and June.[8][5] Observed growing after a burn at the end of May/early June (Arata 1959).

Seed dispersal

This species is thought to be dispersed by gravity.[9]

Fire ecology

Populations of Ipomoea pandurata have been known to persist through repeated annual burns.[10] This species was observed growing after a burn at the end of May/early June.[11] It occurs in mostly longleaf pine communities that are annually burned as well.[5]

Pollination

Ipomoea pandurata has been observed to host pollinators from the Apidae family such as Anthophora abrupta, Bombus impatiens, B. pensylvanicus, B. vagans, Cemolobus ipomoeae, Melitoma taurea, and Peponapis pruinosa.[12]

Conservation, cultivation, and restoration

Cultural use

Historically, the large sweet potato-like root of the plant has been consumed by Native Americans.[13]
