Summary. Recent biodiversity surveys in the Cayman Islands have generated several new records for the reasonably be attributed to recent introduction. Exotics not clearly spreading, but known to be weedy elsewhere, were often seen in planted lawns and in landscape situations. Notable among these were Hydrocotyle umbellata L. and Polypremum procumbens L. found apparently as accidental introductions in recent landscaping at the Queen Elizabeth II Botanic Park and several large fruiting specimens of Melaleuca quinquenervia (Cav.) S. T. Blake in a landscape planting on Cayman Brac. Also, several grasses previously unknown in the Cayman Islands were observed in cultivation in Georgetown and environs. The species observed included Cymbopogon citratus (DC.) Stapf, Pennisetum setaceum (Forssk.) Chiov., Pennisetum macrostachyum (Brogn.) Trin., Phyllostachys sp., Pogonatherum paniceum (Lam.) Hack., Tripsacum floridanum Porter ex Vasey, and Tripsacum dactyloides (L.) L. The flora of the Cayman Islands is dynamic and work continues on cataloguing and conserving the biodiversity of the islands. There will certainly be more species found (e.g. an as yet undetermined Drypetes found recently in the Mastic area) and some will certainly disappear. We will continue to report on the developments.
