If the plant described above is the T. elatum of Mr. JYu t- 

 t all, of which there can be little doubt, I am obliged, in this 

 instance, to difl'er from that acute Botanist. Having com- 

 pared the former with European specimens of T. maritimum^ 

 I find no difference, except its oblong, rather than ovate fruit. 

 Even among the latter, however, I find some with the fruit 

 nearly as narrow as in the North-American plant.
