Best known as "Cook's scurvy-grass." The entire plant has a heavy disagreeable smell and hot biting taste. It was originally discovered by Banks and Solander during Cook's first voyage, and at that time must have been abundant, for Dr. Solander speaks of it as "copiose in littoribus marinis," and Cook states that boat-loads of it were collected and used as an antiscorbutic by his crew. It is now quite extinct in several of the localities he visited, and is fast becoming rare in others. Its disappearance is due to cattle and sheep, which greedily eat it down in any locality they can reach. The figure in the unpublished Banksian plates represents var. frondosum; but the specimens in the set of Banks and Solander's plants presented to the colony by the Trustees of the British Museum all belong to var. acutidentatum.
