The color of this is red, the fubftance meirbra- 

 naceous and pellucid, without rib or nerve-, the 

 ordinary height of the whole plant about four

The leaf when fimpie is elliptic and lanceolate ;

 order, all dented on the margins, like the pri- 

 mary leaf, with numerous cilia of very unequal
