1. Lepidium oleraceum – Cook’s Scurvy Grass is of course not a grass but a large shrubby cress with a flavour not unlike watercress.

Remarkable and unexpected diversity of scurvy grasses discovered on the Chatham Islands

The New Zealand scurvy grasses (Lepidium species) include the famous Cook’s scurvy grass (L. oleraceum), a species which has gained almost legendary status as the plant that saved Captain Cook and his crew from the depredations of scurvy. Whilst modern research has shown that this is gross exaggeration it cannot be doubted that this plant and its allies were important green foods for not only scurvy ridden sailors but iwi (who in New Zealand knew the plants collectively as ‘nau’).
