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 [1]. Species of the genera Commelina can be separated from those of Tradescantia by having unequal petals, one is distinctly smaller (Wunderlin and Hansen 2011). Leaves are alternately arrange and develop along the nodes[2]. Flowers are actinomorphic, blue, and have three fertile stamens and two staminoids[1].
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 (Holm et al. 1977).
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 (FSU Herbarium). 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 (FSU Herbarium). Associated species include Alternanthera, Polygonum, Carex, Hypoxis curtissii, Paspalum, Panicum, Alternanthera, Ludwigia, Murdannia, and Hydrolea (FSU Herbarium).
Phenology
Flowers are actinomorphic, blue, and have three fertile stamen and two staminoids[1]. Blooms April through October and fruits April through September (FSU Herbarium).
Seed dispersal
The fruit is a five seeded capsule with one seed indehiscent seed in the dorsal locule and two dehiscent seeds in the ventral locule (Faden 1993).
