The status of an endemic australian seagrass, Cymodocea angustata Ostenfeld

Although Cymodocea angustata Ostenfeld was based on a 1914 collection in beach drift at Carnarvon, W.A., it was not collected in situ until 1979 when it was recorded at South Hermite Island in the Monte Bello Islands. In 1982, it was found growing at five sites in Shark Bay. From a comparison of isozymes, secondary compounds and laboratory cultures, C. angustata appears to be distinct from other Cymodocea species.
