Taxonomic Notes
Synonyms: Centella erecta (Linnaeus f.) Fernald; Centella repanda (Persoon) Small.[3]
Varieties: none.[3]
Description
C. asiatica is a perennial forb/herb or subshrub of the Apiaceae family native to the Pacific Basin, excluding Hawaii. [1]
Distribution
While native to the Pacific Basin, C. asiatica has been introduced in the United States in Hawaii, Oregon, and Florida.[1]
Ecology
Habitat
C. asiatica is a facultative wetland species[1] and is found in savannas, pondshores, ditches, and a wide variety of other moist to wet habitats.[2][4]
C. asiatica increased its crown cover and biomass in response to heavy silvilculture in North Florida. It has also shown additional regrowth in reestablished pine flatwoods that were disturbed by silvilculture,[5] and increased its frequency in response to soil disturbance by clearcutting and chopping in North Florida flatwoods forests. Additionally, it has shown positive regrowth in reestablished native flatwoods that were disturbed by clearcutting and chopping.[6] C. asiatica was found to be an increaser in its short-term response to single mechanical soil disturbances.[7]
Associated species include Xyris isoetifolia, Hypericum lissophloeus, Hypericum sp., Rhexia salicifolia, Taxodium distichum, Fraxinus profunda, Quercus laurifolia, Polygala lutea, Pluchea baccharis, Sarracenia flava, and Proserpinaca pinnata.[4]
Phenology
C. asiatica has been observed flowering from April to August as well as September and October.[8][4] It has been observed fruiting in August, October, and November.[4]
Seed bank and germination
Seed germination is greatest in low dunes, dry and wet swales, and marsh spoils.[9] It is prevalent in seed banks where it is found.[10]
Fire ecology
A study found C. asiatica to significantly increase in frequency in response to multiple disturbances, including burning, clearcutting, stump removal, shearing and piling, and discing in north Florida.[11]
Herbivory and toxicology
In some Asian countries, C. asiatica is a host plant for the false spider mite (Brevipalpus californicus).[12]
Conservation, cultivation, and restoration
Cultural use
The leaves are used pharmaceutically as an anti-inflammatory and as a diuretic.[13] It is also medicinally known to be aromatic, a narcotic, and used against leprosy.[14]
