Versatile Modes of Propagation inCladium jamaicensein the Florida Everglades
The Florida Everglades is a subtropical wetland dominated by Cladium jamaicense (sawgrass), a native sedge that forms extensive, monospecific stands. Sawgrass exhibits several modes of reproduction, including sexual (seed production) and asexual (rhizome propagation) types. In this study, the occurr...

The Florida Everglades is a subtropical wetland dominated by Cladium jamaicense (sawgrass), a native sedge that forms extensive, monospecific stands. Sawgrass exhibits several modes of reproduction, including sexual (seed production) and asexual (rhizome propagation) types. In this study, the occurrence of vegetative proliferation on the reproductive organs of sawgrass, a phenomenon otherwise known in arctic-alpine habitats, was observed. This is the first time that vegetative proliferation has been reported in Cladium . Vegetative plantlets developed in the spikelets of the inflorescence but also commonly at the lower nodes on the inflorescence. The number of plantlets per inflorescence ranged from 400 to 4000.
