Plants Collected in Paraguay. 225 



Asuncion (var. hirta, Muell. Arg.) has lanceolate leaves, acute at 

 the apex, rounded or slightly cordate at the base, crenate-serrate, 

 sparsely pubescent, 5-9 cm. long and 1-2 cm broad, on petioles 1-3 

 cm. long; stems covered with long spreading hairs and also a close 

 retrorse tomentum. The form on the Pilcomayo has broad ovate 

 leaves, cuneate or rounded at base, and petioles sometimes 8 cm. 

 long; stems with long, scattered, spreading hairs. Staminate spikes 

 slender, 2-6 cm. long, usually on the stem below the pistillate, both 

 kinds numerous. Pistillate spikes and flowers much larger than 

 the staminate. The long exserted, rose-red and thread-like fringed 

 styles are quite ornamental, and lend a beaut}^ to this rough weed 

 which it would not otherwise possess.
