Taxonomic notes
Asclepias is named for Asklepio, the Greek god of medicine and healing.[1]
Synonym: Oxypteryx curtissii (A. Gray) Small.[2]
Varieties: none.[2]
Description
Asclepias curtissii is a long-lived perennial that dies back in the fall and resprouts in the springs from an underground taproot (Mondo et al. 2010). Leaves are opposite and glaborous, with flowers arranged in dome-shaped umbels (Putz and Minno 1995).
Distribution
A. curtissii is an endangered perennial that is endemic to the Florida scrub in the central and southern peninsula[3] (Mondo et al. 2010).
Ecology
Habitat
In the Coastal Plain in Florida, A. curtissii can be found in scrubs[4][5][3] with Quercus myrtifolia, Q. chapmanii, Lyonia, Ilex, Selaginella, Lechea, pines and palmettos.[4] It has also been found in recently bulldozed low ancient scrub. It has been observed to be concentrated along roadsides seven times more often than in surrounding undisturbed habitat (Putz and Minno 1995). A. curtissii exhibits no significant response to soil disturbance by clearcutting, bracke seeding, single roller chopping, broadcast seeding, high-severity burn, and salvage logging in Central Florida.[6]
Phenology
Asclepias curtissii has been observed to flower from May to August, with most flowering in August.[7] Michelle Smith observed Asclepias curtissii flowering August 2015 at the Jupiter Inlet Lighthouse Outstanding Natural Area (Nature Preserve) in Tequesta (Palm Beach County), FL.
Seed bank and germination
It has been observed to grow in close proximity to woody vegetation and unlikely to be found in open gaps due to seed germination being enhanced by shade and not leaf litter (Mondo et al. 2010). Seeds planted in shaded areas among other shrubs have a higher rate of germination compared to seeds planted in open gaps (Mondo et al. 2010).
Fire ecology
The Nature Preserve in which Michelle Smith observed this species flowering, the Jupiter Inlet Lighthouse Outstanding Natural Area in Tequesta (Palm Beach County), FL., has conducted prescribed burns in the past as part of the restoration project for this area, where the BLM and other organizations are part of PCB.gov
A prescribed fire study done on the Lake Wales ridge found that A. curtissii was a weak resprouter after fire (Weekley and Menges 2003).
Pollination and use by animals
The following Hymenoptera families and species were observed visiting flowers of Asclepias curtissii at Archbold Biological Station:[8]
Halictidae: Lasioglossum nymphalis
Skipper and hairstreak butterflies are the mostly likely pollen vector (Putz and Minno 1995). It is able to regenerate from an underground taproot following herbivory from animals such as deer (Putz and Minno 1995).
Conservation, cultivation, and restoration
It is suggested that A. curtissii be managed in areas of soil disturbance and fire regime (Putz and Minno 1995).
