Extract

Eleocharis sphacelata (Cyperaceae) is a common emergent hydrophyte in wetlands throughout Australasia, and is notable as a particularly large member of its genus, able to grow in water up to 2 m deep (Sainty & Jacobs 1981). It is a perennial species, supporting live emergent shoots throughout the year, and grows only on flooded sediments. In Australia, the water temperature in E. sphacelata wetlands remains mild in winter (c. 6°C) but is high (25–30°C) during summer (Brix et al. 1992; Sorrell & Boon 1992). In this paper we present an analysis of the mechanisms of internal ventilation in this species and their ability to aerate the submerged tissue.
