ANNUAL KNAWEL. Scleranthus annuus. 



Plate 5, fig. 11. 



This is, as its name implies, an annual plant. It is abun- 

 dant in most corn fields and gravelly heaths, of a whitish- 

 green color, many branched, and laying on the ground, not 

 above two or ^three inches high, and in flower throughout the 

 summer and autumn. The leaves are opposite, awl-shaped, 

 and every two joined together. The flowers are of the same 

 greenish-white color as the leaves, quite stiff and rigid in tex- 

 ture, five-cleft at the edge, rather tube-shaped, and borne in 

 little bunches of four or five together, at the ends of all the 

 smaller, as well as the larger branches. The plant is of no 

 beauty, nor known to be of any value. 



O. S. Perennial Knawel, found in Norfolk and Suffolk.
