摘要

This synthesis provides an overview using a phytosociological table comprising 23 releves on the different Quercion pubescenti-sessiliflorae Br-Bl. 1932 associations in the Champagne and eastern Ile-de-France areas. A new association, Listero ovatae-Quercetum pubescentis Thevenin et Royer ass. nov., is described involving two geographical breeds: one breed in the Marne Valley, between Epernay and Dormans (wine-growing area), which is a relict plant community found on the favourably exposed slopes in the valley; and another, is a local breed of the Champagne area found on chalky soil.This community is compared with other thermophilous oak stands in north-eastern France, namely the Rubio peregrinae-Quercetum pubescentis Rameau 1974.
