Taxonomic notes
Description
A description of Quercus inopina is provided in The Flora of North America.
This species is very similar to Q. myrtifolia how ever they can be distinguished in areas of sympatry by soil. Q. inopia occupies nutrient poor soil of St. Lucie type, while Q. myrtifolia occupies slightly more nutrient rich soils on yellow sands of the Archbold variety[1].
Distribution
Q. inopina is endemic to Florida, in the xeric, nutrient poor sands of ancient dunes[2].
Ecology
Habitat
Habitats of Q. inopina include sand pine-evergreen scrubs, dry slash pine flatwoods, and longleaf pine/scrub oak communities in central Florida[3]. Associated species include Quercus chapmanii, Q. geminata, Q. myrtifolia, Fraxinus floridana, Ilex arenicola, and Persea humilis. It composes 30 to 40% of the cover in scrubby flatwoods[1].
Phenology
It has been observed flowering in April and fruiting in August[3]. Acorns mature in two years, with the cup covering half of the nut, and the pubescent cup scales[4].
Seed dispersal
Seed bank and germination
Fire ecology
Approximately 70% of the biomass of Q. inopina is belowground, consisting of a network of branching and anastomosing rhizomes which vertical stems arise in clusters. The allocation of this much biomass below ground allows this species to resprout from rhizomes after fire, within 3 years postfire, the oak may regain its pre-burn cover[1].
Pollination
The following Hymenoptera families and species were observed visiting flowers of Quercus inopina at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera, Bombus impatiens
Colletidae: Colletes brimleyi
Use by animals
Diseases and parasites
Conservation and Management
This species in endemic to central Florida along ancient dunes. Even with it's habitat degrading, the local abundance on protected land causes it to not be considered vulnerable[5].
Cultivation and restoration
