Important publication

JC Roskam, Plant Galls of Europe: Keys to Plant Galls (Zoo- and Phytocecidia) of Central- and Northern Europe. Three volumes hard bound set, 2292 pages, € 399.

The book offers an English translation and modernisation of Herbert Buhr’s 1964/’65 compendium of the European plant galls. Moreover the older work of Houard, that was more specifically aimed at southern Europe has been incorporated, and of course the body of literature after Buhr’s time has been taken into account. All together well over 10 000 species of gall inducing organisms have been treated, keyed out in dichotomous keys per plant genus.
A work of this size without errata obviously is unthinkable. The autor will make them available in this site, on page: Errata to Roskam (2019)
