it occurs generally at or near the Niagara Escarpment) and its season is 

 very brief. After flowering it matures its fruit rapidly and then com- 

 pletely withers away. At Pine it is in its prime about May 30. Of the 

 six known collections made from this station four were made on May 29 

 (1897; 1900; 1904, and 1935), one on May 12 (1877) and one on June 13 

 (1935), but at the last date the majority of the perigynia had fallen and 

 the plants were already badly withered.

16. § PICTAE 



65. Carex picta Steud. Map 488. In Indiana in the unglaciated region 

 only where it is local and largely confined to the northern half of the knob 

 area (Chestnut Oak Upland). It is found on wooded hilltops under oak, 

 chestnut, and beech, generally forming rather extensive colonies. Deam 

 has noted that it "has the habit of growing in circular tufts with a hollow 

 center" and from this characteristic the species may be readily recognized 

 long after its flowering and fruiting season is past. It is the earliest 

 sedge to bloom in the state, coming into flower in early April or even in 

 late March.
