Taxonomic notes

Synonym: Dichondra repens J.R. Forster var. carolinensis (Michaux) Choisy.[1]

Varieties: none.[1]

Description

Dichondra carolinensis is a perennial herbaceous species with a ruderal growing habit.[2]

For D. carolinensis, they are a "prostrate, spreading or matted, pubescent perennial, rooting at the nodes. Leaves suborbicular to reniform, mostly 1-3 cm wide, sparsely pubescent beneath; petioles 1-4 cm long. Flowers small, axillary, solitary; sepals 2-3 mm long at anthesis, the outer surface pilose; corolla white, rotate-campanulate exceeded by the calyx; pistil of 2 nearly separate carpels, stigmas capitate, styles separate. Capsule 2-lobed, each lobe usually 1-seeded." [3]

Distribution

D. carolinensis is native from southeast Virginia south to southern Florida, and west to Arkansas and Texas. It is also in Bermuda and reported in the Bahamas, and can sometimes be adventive beyond this range.[4]

Ecology

Habitat

Generally, D. carolinensis can be found in disturbed areas like lawns and roadsides as well as most pinelands.[4] This species prefers dry loamy sand and high light levels. It occurs in several natural communities, including pine-oak woods and savanna. However, it also tends to be a ruderal species, appearing in disturbed habitat like mowed lawns and roadsides.[2]

Associated species include Viola primulifolia, Cerastium Linaria, Oxalis.[2]

Phenology

General flowering time of this species is between March and May.[4] D. carolinensis has been observed flowering January to May, with peak inflorescence in February, and has been observed fruiting in March.[2][5]

Seed dispersal

This species is thought to be dispersed by gravity.[6]

Fire ecology

D. carolinensis has been found in annually burned savanna, so it has some fire tolerance.[2]
