Contents
Taxonomic notes
Synonym: none.[1]
Varieties: Lactuca graminifolia Michaux var. graminifolia[1]
Description
A description of Lactuca graminifolia is provided in The Flora of North America. This species is abundant where found. [2]
Distribution
This plant can be found from North Carolina to Florida, and west to central Louisiana. There are disjunct populations in southern New Jersey.[1]
Ecology
Habitat
This species is found in pine flatwoods, evergreen scrub oak sand ridges, fallow fields, bordering swamps, and longleaf pine-wiregrass pinelands. [2] Also found in disturbed areas, Lactuca graminifolia has also been observed to grow along roadsides, near campgrounds, around parking compounds, and within moist, sphagnum-filled ditches. [2] It grows in dry, loamy sands as well as moist, grassy areas in open light conditions. [2] Associated species includes Longleaf pine, wiregrass, Phlox floridana, Stillingia sylvatica, Asimina longifolia var. spathulata, Lactuca graminifolia, Stylosanthes biflora, Erigeron strigosa, Baptisia lanceolata, Hedyotis crassifolia, Pterocaulon undulatum, Asclepias humistrata, and Quercus hemisphaerica. [2]
Phenology
L. graminifolia has been observed flowering from March through June, September, and October.[2][3] It has also been observed fruiting from May through June and in October. [2]
Fire ecology
It is found in patches of degraded longleaf pine sandhill after burn and control (no burn) treatments.[4]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Lactuca graminifolia at Archbold Biological Station: [5]
Halictidae: Halictus poeyi
Megachilidae: Dianthidium floridiense
