Unlike all other members of the D. filiformis complex, seeds of D. floridana do not require a preceding period of cold, wet stratification in order to germinate in significant numbers, and freshly sprouted seedlings can be observed in-situ throughout the year (corresponding with overall reduced seasonal influence on plant phenology). Similar to those of its allopatric northern congener D. filiformis, seeds of D. floridana have a tendency to germinate en-masse from locations where spent and newly prostrate inflorescences contact the sandy substrate and deposit many seeds in close proximity to one another. Few seedling plants present within these dense colonies will outcompete their siblings and reach maturity.

The newly described Florida Sundew Drosera floridana (B.Rice) Juve & A.Fleischm. specializes in colonizing substrates of white quartz sand. Although the sand from which these imaged D. floridana emerge appears dry on the surface, in reality localized occurrences of D. floridana are dictated by the presence of rare littoral zone seepages known exclusively from the Econfina Karst Region in Bay and Washington counties, Florida; the same region to which D. floridana is endemic. Within the Econfina Karst Region, D. floridana is restricted to an ecotone of intermediate moisture ephemerality between that of sympatric congeners Drosera tracyi (preferring permanently wet, high littoral zone seepages hosting typical blacksoil bog associates) and Drosera capillaris (a generalist often colonizing the lower littoral zone, with its occurrence not dependent on seepage presence, and frequently with few larger herbaceous bog associates present in habitat). D. floridana congregates in the vicinity of (often subterranean) littoral zone seepage veins, but is mostly limited to areas of inorganic substrate composition (e.g. pure quartz sand) that are devoid of larger competitive flora and that do not remain permanently wet on the surface.

I am thrilled to announce the publication of Florida’s first state-endemic carnivorous plant species: Drosera floridana (B.Rice) Juve & A.Fleischm. This taxonomic treatment represents the culmination of my years of work studying the thread-leaf sundews in-situ across 6 states and 25 counties.

Formerly known as D. filiformis var. floridana, our publication not only establishes D. floridana as a distinct taxonomic entity recognizable at species rank, but further brings into question the legitimacy of its putative affinity to the allopatric, northerly D. filiformis sensu stricto.

As a result of our treatment, Drosera x arenaria (B.Rice) Juve & A.Fleischm. is elevated from Dx californica nothovar. arenaria. Like D. floridana, Dx arenaria is a Florida-endemic taxon, and the only described Drosera nothospecies native to the state.

This article is in dedication to Barry Rice for his long-lasting, passionate and thorough work on the carnivorous plants of America, especially on the thread-leaf sundews— leaves long and prosper!

I would like to thank not only my wonderful coauthor Dr. Andreas Fleischmann for his invaluable input and assistance with this project, but additionally my many collaborators without whom a taxonomic treatment of the D. filiformis complex to this length would not have be possible. Among these are: Jason Ksepka, Fernando Rivadavia, Steve Orzell, Tyler Gramley, and Carson Trexler.

A special thanks goes to my good friend Alexander Dietrick for his supplemental help regarding this project.

I am additionally grateful to the International Carnivorous Plant Society - ICPS for their special online publication of this article.

A new population I discovered of this species during fieldwork in February 2026.

In reality, this undescribed species is more closely related to D. dilatatopetiolaris than true D. petiolaris.
