Stem generally smooth. Leaves terete; those near the flowcKS 

 much dilated at the base, and amplexicaul. Calyx much de- 

 pressed ; margin membranaceous, reddish and veined. 



IIab. In sandy fields and waste places in the suburbs of New- 

 York ; also on tlie sea-coast. 



The S. caroliniajia of Wa Iter is doubtless only a variety 

 of S. Kali, The latter, as ii occurs on the sea-coast, cannot 

 be distinguished from the European plant. The variety /3. 

 resembles S. rosacea. 



2. S. Tragus L.: herbaceous, spreading, smooth ; leaves 

 subulate, flesliy, mucronate-spinous ; flowers subsolitary; 

 calyx subovate ; margin flattened, discoloured. Willd,

 I insert this species with some hesitation, as I suspect Mu h- 

 le 71 berg's plant is only S. Kali. 



3. S. Soda L. : lierbaceous, smooth ; branches ascend-
