Root tapering. Herb glaucous, smooth, fetid and pungent when 

 bruised. Stem from 6 to 12 inches high, solitary, erect, leafy, 

 with many wide-spreading branches. Lower leaves pinnatifid, 

 which the figures of the old authors, except Petiver, do not ex- 

 hibit ; their segments are linear, partly toothed, especially at 

 the fore side ; upper leaves undivided, entire. FL minute, in 

 dense corymbs, which when in seed become very long, rather 

 crowded, clusters. I have never met with any petals, nor more 

 than 2 stamens ^ but Dr. Withering, like Scopoli and Gouan, 

 has often seen complete^oj^ers, and sometimes 4 stamens. Pouch 

 roundish, with a notch containing the verj' short, thick, perma- 

 nent style.
