 bearing a small black gland. 



A large genus chiefly tropical in the New and the Old World, extending also into the 

 cooler regions of N. America, and one species crossing over to N.W. Em-ope. The greater 

 number of tropical American species have however been recently separated, by purely artifi-

 Linncea, xxvii. 687. Leaves radical, linear-lanceolate, very pointed, about 

 4 to 6 in. long and 2 to 3 lines broad. Scapes sometimes scarcely longer, 

 sometimes near 1 ft., scarcely angular. Flower-heads ovate-globose ; the
