The scrub on the lower and drier ridges is poorer and more invaded by 

 weeds, and species common in the grass-lands occur. Whether or not the forest 

 once extended over these ridges is hard to tell, but not impossible. On the south 

 side of the island communities of small shrubs alternate with grass- and weed-land; 

 they will be treated together. 



32. (3.) Pernettya- Escallonia-'^oc\2X\o\^. Bahia Cumberland, Cordon Escarpado, 

 on the peak, c. 360 m, 17/12 1916. Dry, barren and stony ridge separating Que- 

 brada del Minero from Pangal.
