Description
"Diffuse, decumbent, pubescent to pilose annuals or perennials, the stem 1-7 dm long or tall. Leaves opposite, connected by fimbriate stipules, lanceolate to elliptic or weakly oblanceolate, 2.5-7 cm long including the often indehiscent petioles, 1-2 cm wide. Inflorescences terminal, glomerate, involucrate, the bracts ovate or widely ovate-lanceolate, often dimorphic; corolla white, funnelform, lobes shorter than tube, anthers inserted at the rim of the tube. Fruit leathery, 3-4 mm long, separating into 4 in dehiscent carpels." [2]
"Annual. Corolla 5-6 mm long, lobes less than 1/3 the length of the tube. Fruit tuberculate." [2]
Distribution
It is observed in South Carolina Coastal Plain. [3]
Ecology
Habitat
In the Coastal Plain region, R. scabra can be found in woodlands and upland pine communities. [4] It can also be found in vacant lots, roadsides, abandoned fields, and powerline corridors. [4] [1] It grows in fine sandy loams, that are poorly drained with slow permeability. [3]
Phenology
It blooms from June through December. [1]
Pollination
Deyrup observed these bees, Agapostemon splendens, Augochloropsis sumptuosa, Anthidiellum maculatum rufimaculatum, Megachile mendica, M. texana, Apis mellifera, and Bombus pennsylvanicus, on R. scabra. [5]
The following Hymenoptera families and species were observed visiting flowers of Richardia scabra at Archbold Biological Station: [6]
Apidae: Apis mellifera, Bombus pennsylvanicus
Halictidae: Agapostemon splendens, Augochloropsis sumptuosa, Lasioglossum lepidii
Megachilidae: Anthidiellum notatum rufomaculatum, Megachile mendica
Sphecidae: Ammophila pictipennis, Cerceris tolteca, Prionyx thomae, Stictia carolina, Tachytes pepticus
Vespidae: Leptochilus republicanus, Parancistrocerus salcularis rufulus
Use by animals
Richardia scabra was heavily fed on by Gopher tortoises in agricultural areas of southwestern Georgia. [7]
