Addendum

In early 1958, the following additional species were collected by one of us (E. A. M.) on the Chatham Islands:

Holcus mollis L.

Juncus pallidus R.Br.

This species has not been previously recorded in any of the published lists of species indigenous in the Chatham Islands, and we think it may have been accidentally introduced there as an impurity in grass seed from New Zealand. It is suggested that the following note by Chudleigh may refer to this species, since it is certain that Typha, the only plant which might be given the vernacular name “bulrush” is, and always has been restricted to a single, small site. Chudleigh (Richards, E.C., Editor), Diary of E.R. Chudleigh, 1862-1921, Chatham Islands, Christchurch, 1950, writes (p. 419): “24th [December, 1903]. Cut bulrushes. The bulrush is about 7ft high and ¾in thick at base, has a feather-like tuft of seed, rich green stalk, white pith inside used as a wick for candles by some people. It looks as if it is out [ought] to be of use but I only know it as a pest.” He states further (p. 426, “26th [December, 1904]. Tried the effect of arsenical poison on a terrible bulrush that is spreading like wildfire, acres per annum. You may cut it down and burn it when dry. It thrives on both.”

Lepidium virginicum L.
