Taxonomic notes
Portulaca is the old Latin name for purslane, referring to the milky sap. Pilosa is Latin for hairy[1].
Description
A description of Portulaca pilosa is provided in The Flora of North America.
Portulaca pilosa has small terete leaves and small lavender-pink flowers, while P. amilis has larger succulent flat leaves and large orange-red flowers [2].
Ecology
Habitat
In the Coastal Plain in Florida, P. pilosa occurs on river sandbars, along highways, lawns, disturbed wet sands of river bays, sandy roadways, and dry loamy sand in parking lots. Soil types include loamy sand, sand and fine gravel. Associated species include Portulaca amilis, Chamaesyce, and Solidago altissima[2].
Phenology
It flowers in July [2]. In Mexico and the lower southeastern U.S., it is a tetraploid; in the southeast it is a diploid[3].
Under low light intensity and temperatures, flowers can not open, this results in a tendency towards cleistogamy, and encourages selfing[4].
Seed bank and germination
It can lie dormant in the seed bank for up to 40 years before sprouting[5]. Light is required for germination[4].
Pollination
The following Hymenoptera families and species were observed visiting flowers of Portulaca pilosa at Archbold Biological Station (Deyrup 2015):
Halictidae: Lasioglossum tamiamensis
