SEDGES. 



On the lowlands, and especially on wet, boggy soil, sedges of many 

 species are found, sometimes in mixture with grasses and occasionally 

 on excessively wetland, constituting a large percentage of the vegeta- 

 tion. As a class the sedges are of much less importance than are the 

 grasses, yet some species of this family are worthy of note as useful 

 pasture plants, while others should be mentioned as weeds which 

 crowd out and suppress more useful species. In the wet season, when 

 the sedges are specially abundant, they furnish a very considerable 

 amount of the lowland pasturage. They are of greater importance on 

 ranges where carabao are pastured than on land where cattle are 

 grazed, since animals of the former class naturally feed upon the 

 coarser types of vegetation. The follownng is a list of the species of 

 the sedge family now in the station collection :
