tinct from any other portion of the group. Two of the setae 

 are longer and stouter than the rest and plicate in the upper 

 third. The chaffy paleae are very lacerate, the lacerations 

 long, frequently becoming short setae. From the descrip- 

 tions, crispus Cass., and spiralis Less., apparently do not 

 belong in this genus. As a well recognized species, we have 

 the very common tropical spicatus, first described from Ja- 

 maica, enormously variable and now introduced into the Far 

 East. The miscellaneous series of specimens that have been 

 picked up here and there, show this species to be composed 

 of a number of very distinct and interesting forms. In no 

 case in the Elephantopeae is there such need for the collection 

 of large suites of specimens at every possible point. Kuntze 

 in the Revis. Gen. Plant. 1 : 335, recognizes two varieties, 

 but this does not begin to enumerate the forms which exist, 

 and hence which we must recognize. Perhaps the glaber of 

 Sesse and Mogino is one of the many forms. Some speci- 

 mens have the achene thickly haired, others thinly; in some 

 the achene is about 6 mm. long, in others 7.5; in some the 

 smaller setae of the pappus are but 5 or 6 in number, in 

 others they are numerous ; in some the floral leaves are 

 shorter than the glomeruli, in others they are longer ; and 

 these characters occur in most confusing combination. Wide 

 variations in vestiture and foliage commonly occur. Whether 

 any of these be of specific value can only be ascertained by 

 the examination of far more material.
