Fritsch, F. E. and W. M. Parker. The Heath Association on 

 Hindhead Common. (New Phytologist. XII. p. 148—163. 4 tigs. 

 1 pl. 1913.) 



This heath in Southern England has been systematicall}' 

 charted, and diagrams and photographs are given to show the sur- 

 face and profile distribution of Calhuia, Erica cinerea, Ulex minor 

 the major association, and several smaller associations. Ulex minor 

 {U. natius) and U. etiropaeus do not grow together, the former fol- 

 lows Calluna and two forms are recorded, a procumbent and an 

 upright, each with a distinct regional distribution. The observa- 

 tions include studies on recolonisation of areas destroyed b}^ fire 

 in different years The following stages occur: Ulex sprouts from 

 old plants within a year, later the erlcaceous species rejuvenate 

 partly from old plants, partly from seedlings, then comes a phase 

 of competition which ultimatel}'^ results in dominance of CaUiina and 

 Ulex minor. Some observations are also given on the recolonisation 

 of gravels on the heath exposed by landslide, in this case the new 

 Vegetation arises entirely from seedlings, and other plants (e. g. 

 Riimex) may for a time be important. W. G. Smith.

 p. 100-102. 1913.) 



This note indicates the present condition of the Midlands of 

 England, originally forest, but later ploughed and now largely 

 grassland. During the survey of such an area, certain species were 

 found in local places and the view is put forward that there are 

 vestiges of the flora of forest or of associations corelated with forest, 

 such as marsh and bog. A list of species characteristic of certain 

 Lias & Boulder Clay geological formations is given.
