Description
Hypericum crux-andreae is a perennial shrub.
Distribution
Ecology
Habitat
It is found in longleaf pine-wiregrass flatwoods[1] and titi-cypress swamp communities in Florida.[2] It can also occur in some disturbed habitat like fallow fields (FSU Herbarium). Associated species include Andropogon, Pinus palutris, Aristida stricta, Cyrilla racemiflora, Salix humilis, Cephalanthus occidentalis, Saccharum sp., Dichanthelium scoparium, Smilax rotundifolia, Proserpinaca pectinata, and Hypericum brachyphyllum (FSU Herbarium).
Phenology
Flowering has been observed in August through October, and fruiting has been observed in October (FSU Herbarium).
Seed dispersal
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years.[3]
Fire ecology
This species has been found in habitat that burns frequently (FSU Herbarium).
