in a slight degree. It appears to be an acrid narcotic, and is apt to 

 produce very unpleasant symptoms after being exhibited ; dimness of 

 sight, giddiness, dilated pupil, spasms of the muscles of the eyes, and 

 even convulsions are reported by Barton to have been brought on by it.

 acute, nearly equal, wavy, sometimes crenate lobes. Filaments dilated 

 and channelled, as well as perfectly smooth, in their lower half; glandu- 

 lar and downy at the summit. Anthers smooth, brown. Ovary downy 

 all over as well as the style. Stigma of 2 large, distant, globular, yellow
