The structure and continuity of the lacunar system of the seagrass Halophila ovalis (R. Br.) Hook f. (Hydrocharitaceae)

Lacunae occur in the leaves, petioles, rhizomes and roots of Halophila ovalis (R. Br) Hook f. While continuous within organs, they are interrupted between organs by diaphragms one cell thick. These diaphragms are perforated by interstitial pores (0.5–1.0 μm). The diaphragms provide a physical barrie...

Zusammenfassung:	Lacunae occur in the leaves, petioles, rhizomes and roots of Halophila ovalis (R. Br) Hook f. While continuous within organs, they are interrupted between organs by diaphragms one cell thick. These diaphragms are perforated by interstitial pores (0.5–1.0 μm). The diaphragms provide a physical barrier to flooding, but allow gas continuity to be maintained within the lacunar system.
