Genecological Studies of Rumex Crispus L.

SUMMARY Samples from 23 British populations of Rumex crispus L., including material of three principal variants described in this species, were transplanted into two garden trials. It was discovered that some characteristics, which distinguished the variants in the field, were less evident or less clear‐cut in cultivation. However, plants from different habitat types did remain distinct in certain features, in particular, the time of first flowering and pattern of tubercles on the fruits. Some variation between populations within habitat types was detected by the transplant experiments.
