Taxonomic notes
Warea carteri is most similar to Warea cuneifolia. It differs by having a stronger pubescence of its petal claws and always having a white corolla. And it is geographically distinct from Warea cuneifolia.[1]
Description
A description of Warea carteri is provided in The Flora of North America.
Distribution
The only known populations are in the scrub habitats of the Lake Wales Ridge in Lake, Polk, and Highlands County, Florida.[2]
Ecology
Habitat
In the Coastal Plain in Florida, W. carteri occurs in sand scrub, Quercus laevis- Serenoa repens communities.[3] This species is endemic to south and central Florida and is found in sandhill, scrubby flatwoods, inland and coastal scrub habitats.[4] The only known populations are in the scrub habitats of the Lake Wales Ridge in Lake, Polk, and Highlands County, Florida. The U.S. Fish and Wildlife Service considers W. carteri to be extirpated in Brevard and Miami-Dave County, Florida. Is commonly found in or near yellow sands. It is also seen in human disturbed areas such as ditches and roadsides.[2] The soil Warea is found in is nutrient poor, moderately to extremely well drained upland oils.[5] This Warea species tends to grow in full sunlight or light shade areas.
Associated species include Pinus clausa, P. palustris, P. elliottii, Quercus laevis, Q. incana, Q geminate, Q. myrtifolia, Q. chapmanii, Carya floridana, Bumelia tenax, Asimina ob ovata, Chionanthus, Lyonia ferruginea, Ilex ambigua, and Serenoa repens.[6]
Phenology
Flowers and fruits in November.[3][7] Warea carteri seems to be inconspicuous when not in flower.[2] Interesting phenology on Archbold’s website on Warea carteri states that “seedlings often remain as rosettes throughout the dry fall-spring season. Seedling mortality is generally highest late in the dry season (Apr-May). Plants that survive the spring drought typically bolt, often doubling in height from month to month. However, there appears to be considerable temporal and spatial variation in growth rates, perhaps having to do with differences in annual rainfall or in microhabitat. For example, seedlings recruiting in shadier microsites seem to elongate sooner than those in sunnier microsites”.[8]
Seed bank and germination
Historically, there were over 200 known patches of Warea carteri on the Lake Wales Ridge but most of the area has been destroyed and converted into citrus groves and residential areas. W. carteri has large population fluctuations associated with fire, such as the population increases a year after a fire and then population decreases the following year. The character of these population fluctuations suggest that seed banks are present. The fruit and seed structures do not have any special characteristics to aid in dispersal. This species can reproduce via selfing (autogamy) which allows contributions to the seed bank after a fire occurs.[9] Seed germination requires moisture and light, flowering is observed from September to October, fruiting is observed from October through November, and seed dispersal occurs in December.[6]
Fire ecology
This species only appears after fire.[4]
Pollination and use by animals
Sweat bees such as Augochlorella aurata and Lasioglossum placidensis (family Halictidae), thread-waisted wasps such as Ectemnius rufipes ais and Isodontia exornata (family Sphecidae) and wasps such as Zethus slossonae (family Vespidae) were observed visiting flowers of Warea carteri at the Archbold Biological Station:[10]
Conservation, cultivation, and restoration
It has been listed federally as an endangered since January 21, 1987 due to habitat loss and fire suppression.[2] This species is endangered in Florida. To protect this species, land needs to be purchased or a conservation easement needs to be acquired for privately owned sandhill or scrub habitat. Manage these sites with prescribed fires and prevent trampling of habitat. Also eradicate invasive species in the area.[4]
