Cyperus odoratus L.
Note: sometimes placed in Mariscus or in Torulinium
Distribution: Pantropical
Habitat: Wet shores, ditches, wet mud
Florida status: Probably native
Recognition: A large, eye-catching sedge of wet habitats. Inflorescence rays each with radiating racemes of yellowish spikelets. These uniquely with a spongy rachilla, this disarticulating and breaking apart into single-achene floating units. Cyperus strigosus can be similar but has flat (vs. round and disarticulating) spikelets.
