Notes on Myosurus minimus

Myosurus minimus L. (Ranunculaceae), exceptionally small individuals (Finland, Järvenpää, Vanhakylä, 1997). Image: Harri Harmaja (scanned from dried specimens). The image shows plants both in flower and at the fruiting stage. The plants of this extensive population, commonly growing tightly among moss, were generally very small. The smallest plants in flower only measured a few millimetres; at the fruiting stage the plants were generally 10-30 mm high. The number of parts of the reproductive organs was commonly reduced. The habitat is a fairly eutrophic area of low rock outcrops with strong human influence, also including lawn. A rich flora was accompanied: e.g., Arabidopsis suecica, Erophila verna, Juncus minutulus, Spergularia rubra, Veronica arvensis, V. verna (and a few planted species).
