inner of as many alternate and larger palecc, cleft beyond the middle into thn 

 scabrous awns; the middle awn twice the length of the two lateral. —This plant 

 has more of the habit of Lebetina than of Adenophyllum coccineum. Were the 

 three aristiform segments of the inner pappus again trifid, it would be a true Le- 

 betina. Although the paleaj are twice as numerous as in Adenophyllum coccineum, 

 and deeper cleft, I refer it to that genus because it is the older one, and should 

 consider Lebetina merely as a section of it, resting the character mainly on the 

 double pappus.

— An early state probably of H. tenuifolium, with the foliage much as in H. pen- 

 tachfetum ; also approaching that species in the tendency to a reduction of the 

 alternate palese of the pappus.

 looked in collecting, I find a single specimen of

Tagetes micrantha. Can. Ic. 4. ^j. 31. t 352; DC. Prodr. 5. j)- 646. Moun- 

 tains around the copper mines. New Mexico; Aug., Oct. (1244.) — " Called Anis 

 by the IMexicans." The plant, raised from Mr. Wright's seeds in the Cambridge 

 Botanic Garden, exhales a powerful and pleasant odor of Anise, when bruised. 

 The ligules are white ("albicans," Car.), usually solitary, occasionally two, and 

 rarely three, in each head, only li to 2 lines long, nearly entire, 2 - 3-denticulate or 

 2-lobed at the apex. Disk-flowers 3 to 8. Pappus of two awns and two broad 

 palea; ; the latter unequal, shorter than the disk-corolla, sometimes connate into a 

 sheath inclosing the awns, Avhich are longer than the corolla.
