Temperate N. Hemisphere 1882

Damp coastal sites.

This sp. has also been referred to in N.Z. as Capsella elliptica, C. procumbens and Hutchinsia procumbens.

H. procumbens was considered native in N.Z. by Kirk. Recent treatments regard it as introduced in S. America [Boelcke, O., Darwiniana 18 : 539-47 (1974)], Australia [Hewson, H. J., Fl. Australia 8 : 292 (1982)], southern Africa [Marais, W., Fl. Southern Africa13 : 98 (1970)] and N.Z. [Allan, 1940, 1961]. The habitats occupied in N.Z. are not dominated by naturalised plants; some are largely undisturbed.
