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]
