Taxonomic notes
Description
A description of Sabal etonia is provided in The Flora of North America.
S. etonia has a subterranean stem that is S-shaped or contorted, with the crown bud held below the soil surface.[1] This species resembles Serenoa repens, however, S. repens has a true palmate leaf with no midrib and sawlike teeth along the edges of the petiole.[2]
Distribution
S. etonia only occurs naturally in the well drained sandy ridges in peninsular Florida.[2] It is distributed in Florida from Clay county south to Lake Okeechobee and then along the east coast south to Miami-Dade county.[3]
Ecology
Habitat
In the Coastal Plain in Florida, Sabal etonia occurs in sand pine/oak scrubs.[4] Associated species include Pinus clausa, Ceratiola ericoides, and Quercus ilicifolia. Grows in well-drained sandy soils and entisols.[5]
Phenology
Flowers in spring. Fruits are shiny black berries.[1]
Seed bank and germination
This species is extremely long lived and experiences limited recruitment of slow-growing seedlings. Both seedlings and adults can persist in drought and wildfire. Seedlings display a type 2 survivorship with constant mortality rates.[5]
Fire ecology
S. etonia displays strong postfire flowering responses, this is typical of many monocots[6]. It is very tolerant to fire[7].
Pollination
The following Hymenoptera families and species were observed visiting flowers of Sabal etonia at Archbold Biological Station: [8]
Apidae: Apis mellifera, Bombus pennsylvanicus, Epeolus floridensis, Mellisodes communis, Nomada fervida
Colletidae: Colletes distinctus, C. mandibularis, C. sp. A, Hylaeus confluens
Halictidae: Agapostemon splendens, Augochlorella aurata, Augochloropsis anonyma, A. metallica, Lasioglossum miniatulus, L. nymphalis, L. placidensis, Sphecodes heraclei
Megachilidae: Coelioxys sayi, Megachile albitarsis, M. brevis pseudobrevis, M. mendica, M. texana
Pompilidae: Paracyphonyx funereus
Sphecidae: Cerceris blakei, C. flavofasciata floridensis, Epinysson basilaris, Isodontia exornata, Oxybelus decorosum, Stictiella serrata
Vespidae: Euodynerus boscii boharti, Leptochilus alcolhuus, Mischocyttarus cubensis, Monobia quadridens, Pachodynerus erynnis, Parancistrocerus bicornis, P. salcularis rufulus, Stenodynerus beameri, S. oculeus
Use by animals
Fruits are eaten by birds[1].
Diseases and parasites
Individuals are susceptible to scale, mites and leaf skeletonizers[9].
