Plants Collected in Paraguay. 133 



The most striking among the herbaceous Composites growing at 

 Asuncion. It occurs abundantly in wet grounds along the river- 

 side. A stout succulent stem 9-12 dm. high, the upper portion 

 curling over gracefully. On the upper side is a row of 10 or more 

 conspicuous heads nearly 3 cm. in diameter, the involucral scales 

 green in the middle and white membranous on the edges, giving 

 them the appearance of a string of rosettes. When open the flowers 

 are very handsome, of a bright rose tint, the corolla lobes curved, 

 the staminate tube and styles long exserted. Leaves lanceolate, 

 often 3 dm. long, deeply cut into triangular, strongly spine-pointed 

 lobes. Oater scales of the involucre also tipped with short spines. 

 Leaves pellucid-punctate. Achenia ornamented with rows of glist- 

 ening glands.
