Description
A description of Commelina erecta is provided in The Flora of North America. In Collier County, FL, an albino form was observed.[1]
Distribution
Ecology
Phenology
C. erecta has been observed flowering from May to September and also in November with peak inflorescence in June and July.[2] In repeated annual censuses conducted in October in permanently marked plots in native longleaf pine-wiregrass communities in southern Georgia, C. erecta appeared only in certain years, seemingly in particularly wet years, and was fairly common in the years that it appeared.[3]
Seed dispersal
This species is thought to be dispersed by gravity. [4]
Pollination
In Daytona Beach, FL, the pollen-feeding bee fly (Poecilognathus punctipennis) was observed visiting C. erecta[5] and performing their unique foraging behavior.[6] The following Hymenoptera families and species were observed visiting flowers of Commelina erecta at Archbold Biological Station:[7]
Halictidae: Augochlorella aurata, Augochloropsis metallica, A. sumptuosa, Lasioglossum nymphalis, L. placidensis
Megachilidae: Megachile brevis pseudobrevis
