In muddy salt-marshes. 



On the shore near Worthing, Sussex. Mr. T. F. Forsfer. At 

 Lynn, Wisbeach, Cley, Holkham, &c. m salt-water ditches, or 

 muddy places overflowed by the tide. 



Annual. August, September. 



Root z\gzng. Stem slender, erect, wiry, smooth, from 3 to 12 

 inches high. Leaves linear-lanceolate, tapering at each end, 

 erect, three-ribbed, rather glaucous. Umbels axillary, solitary, 

 nearly sessile, sometimes disposed in an interrupted spike ; each 

 . of about 3 small yellowish^oii-^?.?. Bracteas 5, awl-shaped, acute, 

 ribbed, nearly equal, rising much above the flowers. Fruit 

 roundish-ovate, with 3 very prominent angles or ribs, besides 

 those at the juncture, to eacli seed, the whole intermediate sur- 

 face covered with fine granulations, as in B. semicompositum , 

 Fi. Grcec. ^ 261 ; to which circumstance Professor Sprengel al- 

 ludes, when he says the fruit of his genus Odontites is " some- 

 what downy." But these granulations are not common to all 

 the species of Bupleurum which are otherwise most strictly 

 allied, nor are they found in B. Odontites itself. I would rather 

 therefore preserve this most natural genus, Bupleurum, un- 

 disturbed.
