Oxalidaceae.

Oxalis corniculata Linn. A stout form of this species with reddish foliage and stems and large flowers [var. corniculata Zucc. forma tropaeoloides (Schlachter) R. Knuth] escapes from gardens, and is established in urban distriets; Feilding, Shannon, Wellington.

Oxalis rubra A. St. Hil. First recorded by Allan (1940, p. 285), but the distribution is not given. Has been found as an established garden escape; Tauranga, M. Hodgkins! Onehunga, H. Carse! Feilding; Palmerston North, V. D. Zotov! Paekakariki, V. D. Zotov! Wellington City and suburbs, H. H. Allan! Riwaka; Nelson; Christchurch. A white-flowered form has been collected at Wellington, R. Mason! This appears to be that cited as establishing in California (Rose, in Leaflets of Western Botany, vol. i, no. 6, 1933, p. 51), but Knuth (1930, p. 203) makes no mention of such white-flowered forms.

Oxalis variabilis Jacq. Recorded by Cheeseman (1883, p. 279) for Auckland. Other specimens have been collected from that area by H. Carse, and it has recently been found to be established in one locality at Wellington. All the specimens examined belonged to var. rubra Jacq. of the species.
