Shore Cotula Leptinella dioica
Endemic. Not threatened.
Generally uncommon in the Manawatū Estuary, at time of writing there is a healthy patch toward the spit off the end of the Dawick Street platform, and a few small patches on the south bank.
The New Zealand Plant Conservation Network entry suggests it has a long flowering season from October to June but here at the Estuary it seems to bloom for only a brief period in early summer.
Flowers can be either green or yellow but it is the leaves which are a distinctive feature of this plant. They are variable but mostly elongated, fleshy with cuts or lobes and either light green, green, blue-green or wine red in colour.
