Status, achene mass, and establishment in the common garden.

Achene mass (n = 4–8), and proportion of established seedlings (Estab., after 161 days; n = 5) in pots in a common garden under control conditions (i.e. without litter cover) and with a litter cover of 400 g m−2 as in the field experiment. Analysis of variance showed that differences in establishment between species were significant (F5,48 = 27.0, p0.23).
