What has passed under the name of P. gradle from the Cape 

 Region may possibly belong to some other species. It usually 

 grows tall and slender, and has a pleasant fragrance which I do not 

 remember ever to have noticed in the specimens about Magdalena 

 Bay. It is called by the natives " Verba del venado "—deer weed. 

 The heads are pale, slender and few-flowered; corolla greenish-white, 

 deeply cleft; the proper tube very slender, nearly as long as the 

 remainder of the flower; akenes all similar, tapering above, about as 

 long as the corolla, and longer than the yellowish pappus. 



P. Jilifolium D.C., as represented by Pringle's "No. 2401, Chi- 

 huahua," has shortly cleft corollas, the gradually dilated throat 

 much longer than the tube; pappus a little shorter than the corolla; 

 scales of the involucre broadly concave, obtuse; akenes not nar- 

 rowed at apex, all alike and free; pappus short, yellowish. 



To this species I refer doubtfully a plant growing on rocky sides 

 of canons near San Jos6 del Cabo. It is of slender growth, about 

 three feet high, with few and large dark purple heads, and long fili- 

 form leaves, the weak stems waving to and fro in the wind. The 

 tube of the corolla is nearly as long as the remainder; the throat 

 widely dilated and lobes rather deeply cut, style yellow, akenes nar- 

 rowed at apex nearly twice as long as the soft white pappus, all alike 



and free. 



P. Seemanni, Schz. Bip. Palmer's " No. 279, Guaymas, 1S87." 

 Flowers greenish, tube about as long as the remainder, throat long, 

 campanulate, lobes very short, styles yellow, branches long and 

 terete, scales of involucre broad, plane, obtuse, akenes hardly nar- 

 rowed, all alike and free. His " No. 216, southwestern Chihuahua," 

 has the tube somewhat shorter than the rest of the corolla, the 

 throat widely expanded and the lobes rather long, style purple, 

 branches long -acuminate, akenes strongly narrowed towards the 

 top. the five outer smooth, each attached to and embraced by the 

 corresponding involucral bract, which is beaked and somewhat 

 heeled, all the inner akenes pubescent. 



"Tagetes is a genus so natural," writes Dr. Gray In Proc._ Am. 

 Acad. , xix, " that no question of its limitation has ever been raised. 

 Yet some of its species connect very closely with neighbormg 

 genera, several like T. Lamnoni, have more or less calyculate m-
