In waste ground, very rare.

 or at least named by his authority. 



Annual. August. 



Stem quite erect, firm, with many upright leafy branches ; panicled 

 and clustered at the top. Leaves alternate, stalked, ovate-lan- 

 ceolate, acute, .slightly powdery or scaly ; the uppermost gra-

 or sinuated, running down at the base into a hoxAereA footstalk. 

 Clusters terminal, erect, compound, many-flowered ; leafless in 

 the upper part. /'/. in short, dense, rather oblong, heads, or 

 blunt spikes. Valves of the seed-bearing cali/x only one third 

 the size of the last, deltoid, acute, tumid ; toothed at the edges ; 

 the disk of both valves beset witii numerous, prominent, strong, 

 acute warts, or teeth. Seed orbicular, blackish, like the pre- 

 ceding, but smaller.

 this plant, and confirms the characters founded on the same 

 parts in the two foregoing species.
