A seagrass with small oval leaves of about 2cm in length, Halophila ovalis the most widely distributed seagrass in Singapore shores (Yaakub et al., 2013). The leaves bears 8 or more pairs of veins. It bears some similarity to the rarer Halophila beccarii, the latter of which is more restricted to mangroves and have narrower leaves.
Yaakub et al. (2013) noted local herbarium records of Halodule pinifolia and Halophila minor/Halophila ovata but the authors postulated these as variants of the Spoon Seagrass, aided by past genetic studies which failed to give sufficient support of them being distinct species.
The Spoon Seagrass is also said to be a staple food for Dugongs.
