 upwards and 2 downwards, all equal, 2-3 lin. long, slender, widely 

 diverging, brown, on narrow horny spine-shields decurrect to an acute 

 point 1-2 lin. below the spines, but not forming a continuous border. 

 Flowering-eyes touching the apex of the spine-shieids. '^o attached 

 flowers, but a cyme mingled with the spines and probably belonging to 

 the plant, is sessile, with 3 involucres on rather slender peduncles | in. 

 long. Involucres 1 J lin. in diam., obconic, minutely puberulous ; glands 

 too decayed for description, but apparently very closely contiguous or
