A still more marked effect of the preponderance of rainfall in the western half of the chain is seen in the vegetation. The lower mountains in the extreme west are wooded, but the extent of forest declines as one moves eastwards. The eastern Pyrenees are peculiarly wild and barren, all the more since it is in this part of the chain that granitic masses prevail. Also moving from west to east, there is a change in the composition of the flora, with the change becoming most evident as one passes the centre of the mountain chain from which point the [[Corbières Massif]] stretch north-eastwards towards the central plateau of France. Though the difference in latitude is only about 1°, in the west the flora resembles that of central Europe while in the east it is distinctly Mediterranean in character. The Pyrenees are nearly as rich in [[endemic]] species as the Alps, and among the most remarkable instances of that [[endemism]] is the occurrence of the monotypic genus ''[[Xatardia]]'' (family [[Apiaceae]]), which grows only on a high alpine pass between the Val d'Eynes and [[Catalonia]]. Other examples include ''[[Arenaria montana]]'', ''[[Bulbocodium vernum]]'', and ''[[Ranunculus glacialis]]''. The genus most abundantly represented in the range is that of the [[saxifrage]]s, several species of which are endemic here.<ref name=EB1911/>
