OBSERVATIONS ON THE GROWTH OP REED CANARY GRASS 

 (PHALARIS ARUNDLNACEA). 



By William Wilson, Junr. 

 TT 7 ITH the view of studying the germination, growth, life- 



history, and peculiarities of grasses, I sowed seeds of 



twenty different species on 5th May, 1886. The soil being a 

 dry gravelly loam did not suit the natural requirements of the 

 Reed Canary Grass. I found braird of this species on 24th May, 

 which was about the average date of the others. 



On taking daily observations I found that between the 24th 

 May and 22nd June it was not among either the tallest or the 

 shortest in its growth ; but by the latter date it had fallen behind, 

 and was, with Meadow Foxtail, Smooth-stalked Meadow Grass, 

 and Sheep's Fescue, one of the shortest of those sown ; and there- 

 after it showed marked evidence of a struggle for life. It was 



Xanthidium, Ehr.
