 slender peduncles 6 to 8 inches high, rarely bractless, 

 usually with one or more leafy bracts below the middle, not 

 rarely parted below the middle into two branches each 

 monocephalous: leaves comparatively short, narrowly spat- 

 ulate-linear and linear, green and glabrate or with a few 

 scattered very long pilose hairs on the lower face or near 

 the margin, rather notably punctate: peduncles more or

 3-lobed at or near the apex, all obviously 1 to 3-nerved : 

 branches short, almost divaricate, the breadth of the plant 

 greater than its height : heads scattered, very large, appar- 

 ently always 5-rayed and the rays more than J inch long, 

 deeply 3-lobed : bracts of -involucre green-herbaceous, obvi- 

 ously distinct, their tips spreading: achenes glabrous, closely
