Description

A description of Manfreda virginica is provided in The Flora of North America.

Distribution

Ecology

Habitat

This species can be found in well drained or poorly drained slopes of longleaf pine forests, savannas, and mesic pine-hardwood forest remnants. [1] It is found in sandy loam habitats and soils are upland coastal plain type with little slope and low fertility, in Louisiana[2] (Thill 1983). It thrives in semi-shaded areas to open areas as well. [1] Associated species include longleaf pine, wiregrass, and hardwoods. [1]

Phenology

M. virginica has been observed flowering in April, and June through August and fruiting in July.[1][3]

Fire ecology

This species is found in annually burned areas. [1]

Pollination

M. virginica is pollinated both diurnally and nocturnally, with observations suggesting that bumblebees are the predominant floral visitors. [4] Bombus pennsylvanicus and Hemaris diffinis are critical diurnal pollinators; however, diurnally pollinated plants were observed to produce significantly lower seed set than nocturnally and open pollinated plants. [4] Hence nocturnal visitors contribute more to M. virginica reproduction despite frequent diurnal visits. [4]
