Description

A perennial species in tropical regions and an annual in subtropical climates. It is a trailing, climbing, twining species with a deep, swollen taproot. [1]

Distribution

It is a native to tropical continental America, and is distributed through out the tropics.[2]

Ecology

Habitat

Habitats include disturbed ruderal areas such as lawns, along railroad beds, and pastures. [3] It has great economic importance in cover crop, forage and prevents soil erosion. [4] A long, deep taproot and the ability to reduce evapotranspiration by shedding its leaves allows for tolerance of dry conditions.[5]

M. atropurpureum can be nodulated by a range of alpha-rhizobial strains, which allow for nitrogen-fixation and allows the plants to thrive in nutrient poor soils. Soil, pH, phosphate, and CaCO3 content and granulation influence the type of rhizobial nodulation that occurs. When M. atropurpureum grows under dry, high temperature conditions, Burkholderia tuberum induces nitrogen fixing nodules. [6]

Phenology

Flowers and fruits August through October. [3] It has been observed that flowering is initiated in response to the onset of dry periods and shorter days while vegetative growth resumes with the return of moist conditions.[7]

In subtropical climates, it displays an annual lifecycle, while in tropical climate is perennial. Perennation of this species has been observed to be associated with survival of the original crowns that develop from seedlings. Individuals that are produced by vegetative reproduction from rooted stolons, are short lived and only survive until the end of the wet season. [8]

Seed bank and germination

Seed reserves are important for individual replacement in subtropical conditions where the species displays an annual lifecycle. [8]

Fire ecology

Post-fire, plants recover well from crowns or stems if perennial and soil seed reserves if annual.[7]

Herbivory and toxicology

Macroptilium atropurpureum was observed at the Archbold Biological Station to host bees from the Apidae family such as Apis mellifera and leafcutting bees from the Megachille family such as Megachile georgica.[9]

Diseases and parasites

This species is susceptible to a variety of diseases and viruses. Under conditions of high rainfall and high humidity, Rhizoctonia solani causes foliar blight that can reduce leaf yields by 80%; however, plants can recover with a return to dry conditions. Synchytrium phaseoli, false rust, occurs during periods of high humidity. Viruses include mung bean yellow mosaic virus and passionfruit woodiness potyvirus.[7]

Conservation, cultivation, and restoration

M. atropurpureum is of economic importance for forage, cover crop and preventing soil erosion. [4] It has been observed to thrive in light stocking and/or rotational grazing. Regular heavy grazing causes loss of buds, shorter plant growth, reduced seed set, and declining soil seed reserves[7].
