Description
A. incisa is a perennial forb in the family Roaceae native to North America [1]. It has tuberous roots and rhizomes, which measure from 2.25 cm to 3.2 cm wide. Fruit is large and barbed, similar to all Agrimonia species [2]. The fruit contains reflexed bristles in the lowermost row, and the whole fruit must be stratified in order to initiate germination [3].
Distribution
A. incisa is found in the Southeast United States, however the distribution is spotty ranging from North Carolina to central Florida and eastern Texas [4].
Ecology
Habitat
A. incisa occurs in sandhills and other upland pine communities.[5]. However, the habitat can vary from mesic longleaf pine woodland to dry pine-oak woodland, and pine plantations [6]. A. incisa occurs on sands located on undulating to hilly sloping uplands that are permeable as well as well drained. A. incisa seems to prefer open woodlands, and disappears as the levels of light decrease [2].
Associated species - Andropogon ternarius Michx., Centrosema virginianum (L.) Benth,, Croton argyranthemus Michx., Dicanthelium aciculare (Desv. ex Poir.) Gould & Clark, Pityopsis graminafolia (michx.) Nutt., Pinus palustris P. Mill., Toxicodendron radicans (L.) Kuntze, and Schizachyrium scoparium (Michx.) Nash [2].
Phenology
A. incisa flowers from late July to November [3].
Fire ecology
A. incisa occurs in frequently burned upland pine communities [2]. It can be seen that fire suppression and the habitat alteration causes a decline in the population [4].
Pollination
The population is predominantly pollinated by small bees within the subfamily Halictinae, including Hymenoptera, Apoidea, and Halictidae [2].
