nervis, C. pilulifera, Liiziila miiltiflora and to some extent L. silva- 

 tica. Nearl}'^ all these are tufted species, this feature being corre- 

 lated with the firmness of the soil, a condition unfavourable for 

 wandering shoots^. 



* The Agrostis spp. are provided with wandering shoots; in the case of A. 

 stolonifera tliese occur above as well as below the ground; in A. vulgaris (themore 

 abundant species in this formation) the shoots are subterranean, but are of miner 

 importance as wandering organs.
