Taxonomic notes
Synonym: Pilostaxis rugelii (Shuttleworth ex Chapman) Small
It is named for the German botanist, Ferdinand Rugel, who collected plants in Florida during the early 1800s.[1]
Description
P. rugelii is an annual species, however, sometimes can be a biennial. In the spring, the irregular rosette is composed of spatulate leaves. The flower stalk arises in summer and the basal rosette will disappear. The stalk can reach 1 to 3 feet high and is often branched.[2]
Distribution
P. rugelii is endemic to the Florida peninsula.[2]
Ecology
Habitat
In the Coastal Plain in Florida, P. rugelii can occur in wiregrass/saw palmetto/pine associations, cypress bays and flatwood marshes. It has occurred in disturbed areas such as cleared pine flatwoods and a recently timber harvested bayhead. It grows in peaty-sandy soil. Associated species include wiregrass, saw palmetto, pine, and cypress.[3]
Polygala rugelii is an indicator species for the Central Florida Flatwoods/Prairies community type as described in Carr et al. (2010).[4]
Phenology
Flowers late summer to early fall.[2]
Fire ecology
Following a fire, flowering of P. rugelii is conspicuous.[5]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Polygala rugelii at the Archbold Biological Station:[6]
Bees from the family Apidae: Mellisodes communis
Sweat bees from the family Halictidae: Augochlorella gratiosa
Leafcutting bees from the family Megachilidae: Megachile brevis pseudobrevis
Thread-waisted wasps from the family Sphecidae: Ammophila pictipennis
Conservation, cultivation, and restoration
Cultural use
Large doses of this species act as a strong laxative.[7]
