Cyperus excurrens (Cyperaceae), a New Species from Karst Ponds in Southern Georgia, U.S.A.

ABSTRACT A novel flatsedge from karst ponds in southwestern Georgia, Cyperus excurrens, is described, and the results of principal component analysis are presented in support of the recognition of this new species. A technical description, dichotomous key, comparative photographs of spikelets and achenes, distribution maps, habitat data, and specimen citations are included. The status of the related taxon, Cyperus strigosus var. stenolepis, is also evaluated.

期刊介绍： Castanea is named in honor of the American Chestnut tree. Castanea is thebotanical name for Chestnuts, dating back to what the ancient Greeks calledthem. The American Chestnut is a critically endangered tree that once made up 35%of the forests of the Eastern US before being devastated by a blight thatdestroyed up to 4 billion American Chestnut trees. Castanea serves professional and amateur botanists by reviewing andpublishing scientific papers related to botany in the Eastern United States. We accept papers relating to plant biology, biochemistry, ecology, floristics,physiology and systematics.
