Lousley, J.E. & Kent, D.H., 1981

Docks and Knotweeds of the British Isles (ed 1)

After a brief introduction, the identification section starts with a brief review of the characters used. This is followed by the dichotomous Key to Genera, then the individual Genus entries, beginning with a short confirmatory description, then maybe a key to sections, followed by key(s) to species.

The major portion of the book consists of detailed species accounts facing line-drawings of the whole plant or a stem, fruiting perianth, fruit, ochrae, perianth, etc.

The final two pages of figures (79 and 80) bring together a set of drawings of Rumex fruits, for comparison or quick identification.

Finally lists are given, with brief descriptions, of Dubious Records of Rumex, Additional Rumex spp Adventive in N. and W. Europe, Polygonum Hybrids Recorded from the British Isles, Rumex Hybrids Recorded from the British Isles, Rumex Hybrids Recorded from Europe (no descriptions for these latter).

A new edition was published in 2014.
