Seagrasses

*Enhalus acoroides*		Found from lower eulittoral zone into the subtidal, on sand and gravel sediments. Long blade like leaves (30–150 cm in length by 1–2 cm wide). Rhizome coarse with many stout unbranched roots; short internodes. This one of the largest seagrasses in the region.
*Thalassia hemprichii*		Found from mid eulittoral zone to shallow subtidal, on muddy sand. Curved leaves (5-40 cm long by 4–11 cm wide) with mass of old leave sheaths at base. Rhizome with distinctive internodes and brown scales. 4 or more internodes between shoots.
*Cymodocea rotundata*		Found on lower eulittoral sandy – muddy sediments. Leaves straight with rounded smooth tips (6–15 cm long by 2–4 cm wide) with shaggy mass of old sheaths at base. Rhizome slender with internodes 1 to 4 cm apart.
*Cymodocea serrulata*		Found from eulittoral zone, on sandy sediments. Leaves similar to C. rotundata but tips are serrated. Base of leaves with distinct light-coloured conical region. Rhizome stout with internodes 2–5 cm apart.
*Syringodium isoetifolium*		Found from edge of eulittoral zone into the subtidal, on sandy – muddy sediments. Leaves narrow and rounded up to 20 cm long and 1–3 cm wide. Rhizome thin with internodes at 1–3 cm intervals.
*Halodule uninervis*		Found from eulittoral zone on muddy sand sediments. Leaves narrow (15 cm in length by 1–3 cm wide) with distinct midrib, leaf tip tridentate. Rhizome creeping with internodes at intervals of 1 to 5 cm.
*Halophila ovalis*		Found from eulittoral to edge of sublittoral zones, on muddy sand (often difficult to see) Leaves oval, small (up to 4 cm in length), oval, in pairs on thin petioles (stalks); distinctive midrib with 8 to 20 pairs of cross veins. Rhizome thin with 0.5 to 5 cm between internodes which are covered by two transparent scales.
*Halophila minor*		Found from lower eulittoral down to shallow subtidal zone on muddy sand. Leaves small elongated oval (0.6–1.2 cm in length by 3–6 cm wide). 7–12 pairs of cross viens. Rhizome similes to H. ovalis.
