There are two tolerably well marked forms of C. gracillima. 

 Schweinitz described the tall and broad-leaved form which grows 

 in rich woods and copses. In open places and on harder soils, 

 the species becomes dwarfed, and may then be known as 



Var. HUMILIS. 



Smaller, the leaves narrower; spikes often very small, two- 



to twelve-flowered, erect or ascending; pei'igynium mostly 

 smaller.
