It is but very lately that we have been enabled to clafs this fpe- 

 cies among the tribes which adorn our (bores. We owe this privi- 

 lege to the information given us by the Hon. Dr. Wenman of All 

 Souls College, Oxford. 



It will be readily diftinguifhed from any other in this divifion, by 

 the fharp thorny appearance of the plant, and by its feffile globofe 

 imooth tubercles, not to mention its rigid texture. 



Murray, who was the firfl who gave a defcription of this plant, 

 mentions the tubercle as fuftained by a fhort footftalk, which fub- 

 tends and is longer than the tubercle. No dependance can be 

 placed upon this remark. The fructification is always feffile at 

 the bafe or axilla of a little branch. In its perfect form this little 

 branch projects beyond the tubercle ; but it is rarely found with 

 any regularity in this (late; for, in confequence of the agitation of 

 the fea, the branch is often broken off; whence the tubercle ap- 

 pears in its true fituation, always leffile, fometimes fmgle on a
