Taxonomic notes
Synonyms: C. longicaulis Jacquin; C. diffusa var. diffusa.[1]
Varieties: none.[1]
Description
A description of Commelina diffusa is provided in The Flora of North America
C. diffusa is an annual species in temperate climates and is either an annual or perennial in tropical and subtropical climates.[2] Species of the genera Commelina can be separated from those of Tradescantia by having unequal petals, one is distinctly smaller.[3] Leaves are alternately arranged and develop along the nodes.[4] Flowers are actinomorphic, blue, and have three fertile stamens and two staminoids.[2]
Distribution
Distribution is not limited to the Southeastern United States, it can also be found in Africa, Asia, South America, Australia, and South Asian islands.[5]
Ecology
Habitat
C. diffusa can be found at loamy lake shores; sandy loam of floodplains; seasonally flooded cypress domes; annually burned pine savannas; loamy sand in mesic flatwoods; wet margins of wax myrtle thickets; and pine-oak-beech-magnolia forests.[6] It has occurred in disturbed areas such as the banks of artificially filled lakes, lawns, roadsides, orange tree groves, unpaved parking lots, levees and ditches. It has been observed growing in loamy sand, sandy loam, oyster shell soil, and alluvial soils.[6]
Phenology
Flowers are actinomorphic, blue, and have three fertile stamen and two staminoids.[2] C. diffusa has been observed flowering from April through October with peak inflorescence in September and October and fruits April through September.[7][6]
Seed dispersal
The fruit is a five seeded capsule with one seed indehiscent in the dorsal locule and two dehiscent seeds in the ventral locule.[8]
Fire ecology
Following a fire, adults will resprout basally.[9]
Pollination
Commelina diffusa has been observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Agapostemon splendens, Augochlorella gratiosa and Lasioglossum pectoralis.[10]
Herbivory and toxicology
The larva of the moth, Mouralia tinctoides, has been observed developing on C. diffusa.[11]
Diseases and parasites
Larva from Liromyza commelinae infests C. diffusa by creating distinct serpentine mines on the upper surface of the leaves.[12]
Conservation, cultivation, and restoration
Stolons can be cut into small pieces and easily regenerate, making it difficult to control. Herbicide has been observed to have a relatively low effect on Commelina.[2] In the United States, it is a major weed in rice crops and reduces rice grain yields. It is abundant in late July and early August, after the first rice crop has been harvested and when the second crop is watered and fertilized, making it difficult to remove.[13] It is also a weed in soybean crops.[2]
