This species grows in close patches of an olive 

 green, or brown colour. The stems are from 4 to 5 

 centimetres long, irregularly pinnate, with somewhat 

 ascending branches. The leaves imbricate one 

 another, and are almost flat, margin entire, the 

 superior lobe stands off obliquely from the stem, 

 is rotundate, almost reniform. The lobule reaches 

 hardly to half the length and breadth of the 

 superior lobe, with which it forms a sharp angle,

 or more or less trapeziform. The female involucral
