A study on the seedlings and tillers of Carex oxyandra , a pioneer perennial, was carried out at Mt. Bandai, Fukushima Prefecture, Japan. A field experiment showed that seedlings had a rather low rate of growth, a small biomass and a high mortality rate. On the other hand, tillers in clones befan growth much earlier, had a rapid growth rate and grew to a larger body size. Furthermore, there was a considerable difference in growth pattern between tillers without flowers and those with flowers; tillers without flowers had a longer growing season and a larger amount of leaves, roots and new rhizomes. The numerical proportions of these two types of tillers in clones varied with clonal vigor.
