 and somewhat polished, closely leafy to the monocephalous 

 or subcorymbose summit ; basal leaves if any unseen, the

 ulate, these succeeded by oval ones oi iH inches or more, 

 those nearer the summit gradually shorter and, the uppermost 

 ovate and % to K inch long, the lower and larger obtuse, the 

 small uppermost acute, all very smooth and glabrous on both 

 faces, only the margins scaberulous with short upturned 

 bristly hairs : heads 1 to 5, small for the plant ; bracts of the
